the top of the indexes, I've seen the reads on this one go from about
1,000 a month to a mere trickle, Everyone skips over the folders and
misses out on a lot of really educational material. Most of the other
threads in the " Important Folders" have done the same and there's a
lot of good information in them.

What Dave says.
There was a wealth of information in those treads. From time to time (actually pretty often) we get new members, or old members new to rimfire, and the same questions come up again and again. There is a great library of information, insights, and experiences here in this forum. I suggest to people who are interested to go read through these, you will learn a LOT about these variants. You will also get a bit of history along the way as you will see the evolution of the .22 AR unfold. Interesting and informative. Take some time and read this stuff.

I wanted to thank everyone who has posted their range reports in this thread. It really is a one stop shop for 22lr AR info. I am hooked now and so os my dad. I got a CMMG conversion yesterday afternoon and couldnt wait to take it out. We loaded it up and took it a small lake outside of town. It was pretty chilli so we couldnt stay long so we each loaded up a mag. He was shooting federal bulk and i was shooting golden bullets. We each went through out mags with big grins on our faces. This this thing is to much fun. We ended up both putting 3 mags down range in about 20 minutes before our fingers were to cold to load more mags. Anyway long story short we had a couple of mis feeds (not worried about it with out of box parts) and alot of fun. Now all we need is to find loads of ammo so we can keep shooting! Thanks again everyone for this fun new addiction!

People used to be able to find this and it answered a lot of questions for many.
Then they decided to group all the important threads in folders at the top of this

along. Everyone should check these old Stickied Threads out in their area of interest.
All of them contain a world of knowledge.

A great library of information in those threads. I don't know where else you could find so much about these subjects. And, as I have stated before, there is a history there so one can follow the evolution of how this came about. Lots of lessons in there and lots of answers to questions many have not even thought about asking yet. I tell people, if you are interested in the .22 AR go read through there, I promise you will learn much and avoid the many mistakes we all made along the way.

What ever happened to the DPMS/Nordic upper? I was all ready to order a Nordic upper....then they went the way of the Dodo, so I just bought a M&P. Then I started thinking about the DPMS upper and now I don't even see them mentioned on their website.
Link Posted: 12/24/2013 11:30:51 AM EDT
DPMS still list the 22 rimfire rifles and uppers on their web site. I think the rimfire products got put on hold after the panic buying when they were talking about banning semi auto rifles. I think a lot of manufactures were trying to build what was most profitable and most highly desired products. I'd be surprised if DPMS drops this version of the AR-22 as it appears to be a solid design.

Tim left them and started TACCOM, that had to be a hit to any updates.
And, I agree about the panic buying, most everything rimfire got shelved
to deliver centerfire. That's probably what happened to our 22 ammo supply.
It's been dribbling out of the ammo makers for a year.

Recently, I made a quick comparison of the cost per round between low-cost but
quality .223/5:56x45 and premium .22lr. Sad to say that in more than a few instances
the two are on par, however, rimfire usually dips a few cents below CF in market
availability situations. Not much of a motivator to justify purchasing it as an inexpensive
alternative to center fire.

Considering the economics vs. efficiency those .22lr AR shooters who are precision shooters are
starting to abandon .22lr in favor of center fire because it makes better sense to just shoot CF. If a brand/load
can be found to deliver reasonable accuracy it eliminates the quirky nature of .22lr. I was surprised to see
a drop off in rimfire shooters at several local ranges during the Thanksgiving weekend. I asked the shooters
why and their reply was "by doing so you are shooting the "real deal" while experiencing greater accuracy over
longer distances with less hassles." CF using brass cases also gives the option of reloading which can further
reduce costs per round while increasing accuracy.

But for the "bullet hose" aficionados the super bulk .22lr will always have the edge. This is the
state of affairs as the manufacturers try desperately to meet demands. I have to add, I'm not
convinced the price of premium .22lr is ever to return to sane price points like just 5 years ago.

You say bullet hose like that is some sort of bad thing.

What I love about .22 is that it is cheap enough that it can be used as a bullet hose.

Case in point, the American 180.

The video below is me doing 275 round mag (well technically a drum) dumps.

Note this is an old video so the quality is not HD and at the time, a brick of .22 was about $10.

They are out there. I purchased a AP4 back in May 2013 and the HB version just two weeks ago from Midway. At that time they had both in stock. Really like my AP4. Have not really had a chance to shoot the new heavy barrel.

I got together with a local Class 3 Dealer to work on one of his Colt M16's
that he's using a CMMG 22 Conversion Unit in. I'd had the dealer pick up the TACCOM
Reliability Kit and install it. After he had done that, testing showed the original
problems to still existed. We started out by checking the firing pin spring, it was
broken. I pulled the one out of the dedicated upper I had taken to use as a baseline
and installed it on his firing pin.

Not believing that to be the only problem, we continued our investigation. By pulling
on the charging handle I found that the bolt assembly was still able to move even with
the TACCOM Pressure Plug installed. 2 ways to help this problem. Install a Rifle Recoil
Spring or Spacer on the top rear of the bolt frame, top rear where the recoil spring guide
rod mounts to the bolt frame. The latter was the best option in this case. We used 8 strips
of Blue Painters Tape as a temporary fix. The carbine ran perfectly with Black Dog Machine
Magazines but would not chamber a round from the new and "Fully Loaded" CMMG Magazine. This
was due to the extra spring pressure needed to operate The CMMG BHOA and my magazines aren't
fully broken in. The springs are still very stiff. To correct this, we installed a stronger
Lakeside Recoil Spring but not the longer version. Now the combination was able to strip a
round from the CMMG Magazine loaded to full capacity with 25 rounds.

We then fired both CMMG's Magazine and BDM Magazines. 7 in total, some using burst and some
just plain mag dumps. Federal and Aguilla Ammo and not a single misfire, misfeed, stuck case
or anything else. The dealer thought I was full of crap when we first started with all of these
seemingly meaningless minor fixes. When we finished, he was totally at a loss for words to describe
his amazement and his opinion of my knowledge and ability had changed drastically.

Some of these problems with this Colt M16 were the parts being used initially, but the problem that
turned out to be the biggest problem was an upper and lower receiver that met the Mil Spec but the 2
receivers were at opposite ends from each other. This allowed for bolt movement within the upper receiver
under fire. The dealer is going to do a weld over the rear top of the bolt frame and file to fit against
the lower receiver. By doing so the bolt absolutely will stay forced into place under full auto fire,
actually negating the need for the pressure plug in this case.

I just wanted to show how little things not being right can add up to a lot of frustration but they are in
most cases easily corrected.

I recently started using my first 22lr conversion, a CMMG Evolution kit. The FCG is a mil-spec with lightened springs and a re-profiled hammer. It works perfectly with .223/5.56 but was 0% with the conversion. Some examination of the hits showed a much bigger firing pin footprint than with my other 22lr's (10/22 and 22/45). Making the face of the pin match in width and narrowing the height about 1/4 resulted in ~90% ignition and mimics the hits of the other 22lr's, just without as much depth. Hopefully some break in will get it firing 100%. If not the hammer will get thinned out. Reliability as far as cycling was 100% with 36gr Federal Champion (which CMMG recommends).

Overall it's a hoot. If it wasn't for the so so accuracy (~1-1/2" at 25 yards with a red dot) I'd have little need for the 10/22. My kid demonstrates:
https://www.youtube.com/watch?v=ShO2KYmRviM

This being used on a 7" pistol. It's quite magical.

The only disappointment was the slight bulge on fired cases. Apparently a compromise of the design, I guess if it works it works.

Narrowed as well as tail removed.

The PSA Mil Spec trigger was a major surprise. With just a trigger spring swap and hammer spring mod it's like a match single stage but with a bit more travel, and the slightest creep. Pre-travel and over-travel are imperceptible.

20140322_014007_LLS by Slick_Rick77, on Flickr
I chose to stick with a mil spec trigger group as they are known for durability. As AR-22's are known to be tough on the FCG it seemed like a logical way to go (and saving a few bucks is nice, too). It's nice to luck out with a decent one.

Primer hits look good though are still not very deep. Ignition is over 99%.

I'm running an older CMMG stainless steel conversion with a TACCOM extreme extractor, firing pin and TWO pressure plugs. It does not have the brass lock collar to secure it in the barrel extension.
It runs 99.9%. The occasional empty brass will get between the charge handle and bolt face.
I've been shooting it in Steel Challenge.
Barrel is 1/9 twist and accuracy is surprisingly good.
I found I had more cycling issues with only one pressure plug. It still allowed the conversion to move fore and aft too much.
Two plugs completely eliminates that.

I keep saying I'm going to build a dedicated upper but this had been so reliable I really haven't seen the need.

Link Posted: 3/26/2014 6:06:45 PM EDT
So glad I found this thread! Wanted to post some results from earlier today.

Yesterday I got in some new optics and wanted to give them a try. The range was not open today so I decide to throw my Ciener .22 conversion in and headed out back. I grabbed a box of Federal bulk and two uppers. The first upper is a DTI 16" 1:9 with a Magpul rear site and standard fixed front site. I shot a 5 round group (upper right) at about 30 yards that was a tiny bit over quarter sized. My eyes really stink which was why I decided to add an optic. So I threw on the new StrikeFire and PA 3x magnifier. Sighted it in with about 8 shots and then shot a pretty nice dime sized group of 5 (left). I then switched uppers to my Rock River 16" 1:8 varmint barrel. This upper has an old Bushnell 3x9 scope. I turned it up to 5x and shot a great 5 round group (bottom).

I was considering building a dedicated .22 upper but I'm not sure or convinced that spending the extra dollars would be worth it. I think I'd rather spend the money and pick up another .22 conversion or two. Maybe something nicer than my old Ciener.

Next up will be to take it to the range and shoot some 50 yard groups with some Federal match and see what I can do.

Link Posted: 3/27/2014 6:48:04 AM EDT
That's some damn impressive accuracy from a conversion.
I keep hearing a conversion is not as accurate as a dedicated upper. I've never had any accuracy issues shooting Steel Challenge.

I'll have to see how my 1/9 and my 1/7 compare with a scope.


Link Posted: 3/27/2014 8:32:32 AM EDT
That was my thought. I was all set to build a dedicated .22 upper but I just don't see what I would gain. Maybe I got lucky and have a really good conversion kit? It's just a basic Ciener one I picked up from Model 1 a few months ago. Going to try a couple more tests but I have to say I'm pretty satisfied as is.

Most of the new 22 guys don't look in the folders at the top

It retains the first four standard positions plus a "compact" position for storage.

The upper is box stock as of now, but the gun will be SBR'd eventually.

Great thread!

I'm in the process of building a dedicated .22lr AR. I'm starting with a Tactical Machining 80% lower and matching stripped upper(purchased already). I have a CMMG .22lr Evolution .22lr conversion. I'm ready to order a barrel and was wondering what is the latest hotness in dedicated .22lr barrels. I've been eyeing the barrel and collar kit from CMMG so far.

https://www.cmmginc.com/shop/barrel-and-collar-kit-16-1-m4-22lr/

I'm guessing that this is an excellent barrel and will give me outstanding performance for the money but before I order it I'm wondering if anyone has a better suggestion for a reasonable price. I'm good with spending more money for a barrel if it's going to be worth the price difference. Also, I do plan on adding a suppressor eventually.

Any suggestions for other barrels or is the CMMG the right choice? Thanks in advance.

I'm guessing that this is an excellent barrel and will give me outstanding performance for the money but before I order it I'm wondering if anyone has a better suggestion for a reasonable price. I'm good with spending more money for a barrel if it's going to be worth the price difference. Also, I do plan on adding a suppressor eventually.

Any suggestions for other barrels or is the CMMG the right choice? Thanks in advance.

I'm not sure if you bought a barrel or not but check out Beyer Barrels. I bought a bull barrel from them about a year ago and it's been a great, accurate barrel. Yea, they are a little more money but well worth it if you want to hit your target at 100 yards.

I have not purchased a barrel yet. I have been putting that off until I get closer to finishing the lower. I'm starting with a Tactical Machining 80% lower that's out for some laser etching work now. :-)

Once I get the lower back I'll get a barrel ordered. I'm not in a huge hurry to do that since I can't decide on how to finish the lower yet.

I've abandoned my SBR idea and am just going to make a fixed sight gun with MagPul midlength handguards (Tacticool22 parts on the way).

Being one to not leave things well enough alone, I liked the idea of a very short muzzle device.

The Carlson Mini Comp looked pretty good.


Being cheap and stubborn I felt the same length could be achieved with the stock A1 flash hider by chopping the FH and cutting the threaded portion of the barrel down to the appropriate 22lr length of .385-.400."

The threaded portion was left at 0.385" and the flash hider is now 1.410."

Pointless? Perhaps...but I like it

It's a 0.34" OAL reduction.

I guess I could always get the Carlson Mini and chop that as well, though I'm not too keen on the looks.

Bump this thread because it was immensely helpful to me and my build.

Whatever happened to the CMMG ALPHA or something like that. It was a very cool interface design with the collar to the barrel breech that looked like it "locked" into place. Once of the guys (Spec-Ops 13 ??) that did a lot of testing had pictures of it but i don't think it ever came to market. This thread was extremely helpful to me too when i wanted a dedicated AR15/22. Before i knew anything, i bought a Colt/Umarex version. It shot well and was pretty accurate but it felt like a toy and it was "proprietary" everything. I wanted something you could take apart and tinker with like an AR15. So i started reading some of these threads on this forum. I then decided to go with the TACCOM ULW upper assembly. I love it. I put together another one with a chrome moly barrel from TACCOM too. They both shoot great. I love them. But I've always been curious about that one thing from CMMG.

It's been a while but if my memory is correct the CMMG Alpha signified the black or phosphate color 22 conversion bolt. CMMG introduced a Stainless Steel 22 conversion bolt and designated it Bravo and Black was designated as Alpha. CMMG used a set screw to hold the collar onto the barrel when first releasing the dedicated rimfire upper. CMMG then went to a spring loaded detent that fit into a groove on the barrel to help keep the 22 caliber bolt in position. Rick Kuhel was the first person to invent/modify or use the collar design in a dedicated 22 rimfire upper to capture the Ciener bolt.

There have been a few different modification and finishes from the Atchisson/Ciener pattern bolt as utilized by Spike's, CMMG, Target Master, and TACCOM. With the shortage of 22 Long Rifle ammuntion the AR-15 in 22 LR really died out. The S&W M&P 15/22 has garnered a lot of the AR-15 22 Rimfire market. Olymipic sold the Military M-261 conversion and now are out of business, Spike's left the 22 rimfire market several years ago. DPMS sold a couple of versions of AR-15 dedicated uppers and conversions but are out of the market. Nordic Components is selling a dedicated 22 LR upper which uses the same pattern bolt as the DPMS and JP Enterprise. Tactical Solution still sell dedicated uppers and there is the cheap copy of the TS sold by Chiappa ATI.

I believe you can still get the CMMG alpha (https://gun.deals/search/apachesolr_search/22BA6FD). Not sure if its actually in stock on those websites though.

Model One sales, compass lake, tacsol is also selling AR22 uppers.

There is a great library of information, insights, and experiences here in this forum. I suggest to people who are interested to go read through these, you will learn a LOT about these variants. You will also get a bit of history along the way as you will see the evolution of the .22 AR unfold. Interesting and informative. Take some time and read this stuff.

This was originally a normal thread but it's slipped back in the index so I'm putting it up here so we can continue to
get, add and correct the information. This is a work in progress. it's the latest information I have. I edit this
post with new information as it comes in or as soon as I can. Eventually, this will be a go to list for the hammers and
trigger / packs and how they will work with various Conversions and Dedicated uppers. It's not perfect yet, it reflects
the information I have compiled from myself and OP as of my last update. Check my "Edit Date" on this post to see
when this info was last updated.


This is a list of various hammers / triggers, usable or unusable for 22 conversions and dedicated uppers.
I realize this isn't a perfect world, that some will be iffy. We're trying to be able to give even percentages of work and
won't work, I need help, if anyone knows of the ones I've missed... Or even variations of the ones I have, Please
IM me so we won't have an excess of posts here in the sticky'd thread... Thanx...
Also, let me know if I am wrong
about any of the information I have. I can edit this post to reflect the info you give me in the IM and we'll always have a
place to look for an answer.

I also realize that some manufacturers may be selling hammers being branded as their own. Help me so I can group
like items too.

These are individual hammers and triggers or trigger packs being used with AR-15 Conversions and AR-15 Dedicated uppers.
When I say "Works with all". I mean there are no known issues with any conversions or dedicated uppers
.

Note: With the release of Nordic Components Upper, it is believed that it will work with any of the following Triggers / Hammers..
Tim at Nordic believes their upper will work with any trigger group combination that will work with an AR-15... Please let me know
if that is not a true statement, Thanx. SpecOps-13

Purchased at auction Saturday what appears to be a Compass Lake upper. Did not know what it was, only that the stainless bbl was stamped 22LR. Did not recognize the bolt design. No mag, but otherwise complete. Still not absolutely sure, but the small parts kit on the Compass website looks to be what this bolt would use. Will call them tomorrow. Have a CMMG conversion in my wife's Yankee Hill upper. Hope this new set up is more accurate. If so, will build an Aero lower for it. Cheers, Robert

Bump!!!

So, it took me a long time but I finally got this rifle sorted. If I'm honest, I just messed with it here and there between working on car project and house boat trips. But, I finally got serious. I ordered about a dozen different types of ammo and tried a few different magazines. Finally, I got it to cycle about 500 rounds flawlessly with Black Dog Machining magazines with stainless feed lips and Aguila Super Extra High Velocity ammo. It's fantastic and a blast to shoot.

I picked up a Spikes dedicated 22 barrel and the barrel extension is larger than my adapter collar. Do I need to resize the extension to fit or is there another option before I go buy a CMMG barrel. Maybe someone has a Spikes collar they don’t need anymore. Thanks for the input.

Spike’s collars are .500 and CMMG is .460. Model 1 Sales used a Atchisson/Ciener pattern bolt with .500 collar. TACCOM uses a .500 collar and sold some Delrin collars which are quieter when using a suppressor.

Really recommend you measure your barrel and current collar as the only two sizes I’ve ever were encountered were .500 or .460 collars.

If you want to buy a steel collar you could call TACCOM or Model 1 sales if you don’t find them on their web site.

Here is the link for the Delrin collar

I’ll try giving TACCOM and Model 1 sales a call. I must have the steel .460 collar and the barrel must be .500. Thanks for the help VASCAR2
