After alittle surfing for a 7.5" barrel for my 7.62 winter build, I could only find one place that had 2 in stock so I ordered one.
Already have a SAA lower and next month I'll order a slickside upper and 4" FF, then finish up with the rest of the parts in February.

Can't wait until the Range Master see's or should I say hear's my newest toy ! I always get a kick out of his comments when I show up with the 5.56 now, or when
I show up with my S&W 500 at the indoor range

So how many AR15.com'ers are rocking the 7.62?  I need a muzzle device that kicks the flames out the sides !!

Got the upper, bolt and mag so far and the barrel should be here by next week.

FF tube should be here soon so all's that's left is pistol buffer tube assy, flashhider and gas block/tube.

It's getting there.

I've got most the parts sitting at the house for my build. Who's bolt carrier groups are you guys using? I've been thinking about grabbing an ar15performance bolt, but I'd still need a carrier.



I think I grabbed my muzzle break from Core 15 Damage Industries. Should be quite the fire breather when she's done.

I'm thinking of getting the Super bolt when they are back in stock, right now I'm going to use a 7.62 DPMS bolt.

Thanks for that link ! I was looking for a muzzle brake and that one pictured is perfect and just what I was looking for.

Glad I could help.  I'm thinking that brake with a 7.5" barrel should really be fun.

My 7.62x39 pistol I just finished. Definately turned some heads first trip out to the range.

What all do you have to do to keep it CA compliant?

Here is mine on my SBR lower. Still needs the BCG, charging handle and muzzle brake.





Is that an Omega rail on yours?

Nice pistols guys

The barrel showed up today and still need a few more things. I'm getting alittle itchy and may just have to cann a few parts off my other pistol if you know what I mean !

Just wondering what parts designed for a .30 caliber do you need? Is it just like building any other .30 AR? (barrel, bcg, Receivers, LPK, etc)...

Different bolt and barrel. Arguably optional firing pin upgrade.

ETA: ...and different mags.
Link Posted: 12/17/2012 8:00:16 PM EDT

All you'll need to do is change 3 items. 7.62x39 mag that fits an AR, 7.62x39 bolt and 7.62 barrel, then it's test and tune time.

So do you use a regular AR15 bolt carrier, and just replace the actual bolt? how much more does it cost to build this over a .223/5.56? Where did you find your barrel?
Link Posted: 12/18/2012 7:02:19 AM EDT
[#13]
Yeap, just swap out the 5.56 bolt for the 7.62 bolt and use the same carrier.

DPMS 7.62 bolt - $70
Midway AR 7.62 mag - $18
Marks Armory 7" barrel - $135

Maybe a new flash hider if you can't fit a 11/32" drill through the end of it.

I picked up Mark's last 7.5" barrel that he had in stock but I couldn't find the gas block size.  For my 5.56 pistol build, I used a .750 gas block.

It's .750

.750 is the standard size for most barrels.  Pencil barrels use .625 gas blocks and bull barrels obviously use larger blocks.  I'm using a YHM 9383 blocks on some of my rifles and I've been happy with them.  They work well for slipping underneath rails.

It's a good thing I bought an extra .750 low-profile gas block.

With alittle luck the rest of my parts should get here right after Xmas too. Time to hunt down some more 7.62x39 ammo.

FF tube and extra mag showed up today and she's getting closer

I hate those mags even the 10 rounders - if you are shooting steel m1s makes a slightly longer firing pin for them now you can get also I added a pof roller cam pin/wul +15% hammer spring and bcm extractor spring - here's my cal legal one with bullet button and 10/30 mag

Link Posted: 12/21/2012 11:49:44 AM EDT
[#21]
That looks sharp how does it shoot ?

I'll just load 20 in each mag cause it does take alittle work to get 30 of them in there.
I was thinking if I have a FTF I might just sand down the base of the firing pin a couple thou and see what happens ? I like to tinker anyhow.

[#22]
the magazines in 08-09 were a pita so I sold it but others I have owned in that caliber shot excellent - the one I built for my friend is like that one and he shoots it all the time.

Well guys the rest of my stuff showed up today and she's together, I still need to do a few upgrades like green dot, pistol tube, cover and muzzle brake.
But as is, I'll get her broken in and any fine tuning that might be needed.

I gotta say I feel lucky that I ordered the major pieces before all this crap about about AWB started up cause I was looking at a spring time completion. I really feel for anyone in a bind right now
trying to get parts. I still can't believe an NFA polly pistol lower is 200 bucks now ??



Big brother and little sis

Great looking pistols!!!

My barrel is in and now I'm looking for a flash hider/muzzle brake.  What's thread type?  I've never paid any attention since all of my builds were 5.56.  I did find a .308 muzzle brake with 5/8x24 tpi.  All else fails, I can check it against my 5.56 flash hider and see if it will fit.  I just wanted to check here to be sure though.
Link Posted: 12/25/2012 2:34:46 PM EDT
[#25]
And I just found one that is 1/2x36 tpi that fits 7.62x39, 6.8 and 9mm.  My idea about the .308 model was wrong.

Thanks, can't wait untill I get to the range now

My barrel from Mark's is 1/2x28 threads, you way want to double check it just to be sure?  I'm just using an A1 flash hider for the time being plus I was able to slide a 11/32 drill bit through it.

Hit the range today and all I got to say is WOW ! I like it   Anybody that has a 5.56 pistol needs to have a 7.62 pistol too !!!

The 7.62x39 build went through 90 rounds, 5 FTF but I reloaded them and they all fired off again after a 2nd try.
Did have a few jams maybe due to no M4 cuts on the slickside upper. So after I got home I filed them in the upper and also took off a couple thou
off the the firing pin so next time out will see how she runs.

Gotta say the kick is pretty awesome, after 30 rounds I grabbed the 5.56 pistol and it felt like I was shooting a .22 if you know what I mean. I did plant my nose alittle close to the charging handle and the 7.62 let me know it didn't like that and gave me alittle thump saying back off dude !

My camera doesn't do the sound justice but here's the 7.62 and then the 5.56. I was really surprised how accurate the 7.62 was first out with no final adjustment to the sights yet.

Now all I need to do is come up with names for my pistols ?

I can't wait.  Everything for mine is on the way except for the bolt carrier group.  I'll just pull that from my 7.62x39 rifle until someone has them back in stock.
Link Posted: 12/27/2012 3:18:14 PM EDT
[#30]
You'll love it, just hold on tight !

I just order a longer firing pin from M1S just in case ? I use the carrier out of my DPMS Sportical with over 2 rounds through it with the new 7.62 bolt with no problems.

Same as rifle just no stock allowed.

Bullet button, No stock, 10 round mag.

Latest update.

At the 300 round mark I had a FTE round and notice the tip of the extractor had broken off. Since I can't seem to find a 7.62 one, and heard that a 5.56 one is stronger so I pickup a field repair kit and put the 5.56 one in. Just got back from the range with good results, all 109 rounds ejected and had no issues Had a blast shooting at a softball too, even got alittle trigger finger crazy and fired 30 rounds as fast as I could !

Here's a pic of the 7.62 extractor and you can really see there's not too much metal where they break at. Will see how the 5.56 one holds up now ?

Good luck ordering anything from Model 1 Sales, I've had my 762 pistol upper on order since middle of Dec and still no word.
Used to be a good company to do business with.

I got the firing pin a couple of weeks ago and works good. I guess they got lot's of them laying around.

Hey Jake be careful with that buffer tube. where I live they would bust you for that. Reason being you can easily slide a stock on there.
Need a NFA stamp to do that........just sayin!
Still nothing from M1Sales. so discouraged I bought a Krink pistol.

Still waiting for pistol buffer tube assy's to come back in stock so I can replace it. For the time being I've already cut and filed that rifle buffer tube until it's round and
glued a rubber pad tube around it, plus I don't have any spare rifle buttstocks laying around so I'm GTG.............. hopefully.

Found a Utuber with one, gotta say I like it
