AEM5, KAC MRE, had the barrel cut so the can would be flush with the barrel.

Need to get it its own lower...

Don't know why the one pic is upside down...

16" BA barrel cut to about 12.1"

Just got this together. AEM5 has only been out of jail a couple days.

I sent Ron an email a month ago about the shoulderless collars, never heard back from him on it. Was thinking about getting an AEM5 for the AUG I'm getting, but I found the Griffin RSTA for not much more than the AEM5, and they weigh roughly the same.

Yep. I've been hard to get in touch with lately, and I haven't had a chance to make any collars. I should be back to normal(well, normal for me) by the end of the day tomorrow. If I've ignored you on a collar, give me a call and I'll get it taken care of this weekend.

I think the angle is off on that collar Pete. Looks like the diameter is a bit big as well. A cup of Rockset should keep it from slipping

You may reach through the phone and choke me.

I need a collar that moves it about 080 towards the muzzle when compared to the standard aem5 collar.  Thankfully, your flash hider mount has more threads than the brake and as is I get 10 turns.

Just now finding this thread as I was exploring the other forums off the beaten path.

I absolutely love the pictures! I built a 6.8 SPC rifle inspired around the Mk 12 Mod 0 and even intended to get an AEM30 for it at some point. Unfortunately though, X-Caliber cut my barrel a little thicker at the business end than I wanted and my AE collar would not fit.

Am I understanding that I can get a custom collar made? If so, id still love to order that AEM30 as the finishing touch for my Mk 12 Look-alike

I have a question....

I was monumentally retarded and did not notice the end of my rail has a high spot.  My can was tightening against that high spot, but only missing seating on the collar by a few thousandths.

The result was lots of carbon and shitty groups.

Both the top and bottom tine of my brake had a super hard line of scaley stuff on it.  It looked like a ground down weld bead. At first I thought it was copper, but there's no baffle strikes.  I scraped it off with a razor.

Never had that on any of my other rifles, however, this is the only rifle that's been mag dumped.

Should I be worried?

This build has had so much weird shit go wrong that I'm doubting myself on everything.  Out of spec upper, leaking gas block at the tube, new gas block and the roll pin comes out at the range...

[Last Edit: k31user] [#28]
The brakes get build up on them fairly quick. Scrape, or soak in CLR and brush off.  If there's no baffle strikes, there's nothing to worry about with the suppressor. It doesn't like not being seated against the collar though. Grouping could suffer.If it shoots well without the suppressor, but not well with it, let me know.

Ron, this isn't on the collar you just made for me. That turned out on the numbers perfect.

This rifle is using a standard collar, but the can is off the rail now.  I switched uppers, was able to ditch the barrel nut shims and gained myself a minimum of 020 clearance all the way around the can.  Surprisingly, when trying to flex the rail by loading the bipod hard I can still squeeze in my 020 gauge.

I still might call you for another collar because it makes me nervous.

Cool. How much space is there in between the front of the gas block and the rear of the AEM5? Is the gas block 1" from front to rear?

The OAL is about 1.25" but the gas block portion is the normal 1". There is the width of a couple credit cards between the can and gas block.

Read this entire thread along with some others and decided to post. I am considering buying my first suppressor (late to the party, I know...). As luck has it, my SPR has an AE / Ops Inc muzzle brake and collar already installed (built by someone else, received by me as new) so I am starting my research with the AEM5.

Unfortunately this barrel does not have the profile for the collar to index off of - currently it is held in place via the set screw only. I have read a few conflicting reports, but it appears to me that this should work but is not the correct setup, as the collar should index from the barrel profile?

I also discovered that the brake was not timed correctly. The large web is up, and what I have read it should be down (small up). From a performance standpoint it hasn't seemed to matter much but I need to obtain a couple of shims and try to fix it (crush washer alone isn't working).

If I can make this setup work as is, the AEM5 is going to top my list in 2019 to enter the NFA game. Otherwise I may have to consider switching out the brake or going with another suppressor.

Set screw will not hold the collar in place when you put a suppressor on it. Hand tightening the suppressor will over power the collar screw.

You could either have a step put in the barrel or have a custom no step collar made.

I don't know if I would trust a dimple and the setscrew.

Thank you, that was what I expected but needed to verify. I saw a few posts where it seemed people relied on the set screw but that was definitely not correct.

How would a "no step collar" work on this? Does it use the barrel threads to index? Research continues....

I've always wondered, is the set screw just there to stop the collar from rattling with no can?  I.e. if the can never comes off, one wouldn't technically need it, correct?

The set screw is just there until the Loctite sets up. Yes, a dab of green or blue loctite is recommended to set the collar in place on the barrel step.

Any of you with an A1 style build with the AEM5, did you have enough clearance for the long collar with the FSB?  I know I’ll have to remove the bayonet lug, but I don’t know if the collar will be too long and contact the base.

Another question for you guys.

If I went with a 12.5 barrel with low pro gas block, can I get a M4 collar to work with it for an AEM5?  No other contouring of the barrel needed....correct?  Just have the correct  threaded brake or flash hider and I should be good to go?

Correct if the barrel has the M4 profile towards the muzzle. I know Ballistic Advantage and DD are good to go. You can even get away with a FSB but may have to slightly shave the bayonet lug.

There was a little trial and error to get it right but I believe it’s something like 13.07". At first it was cut to 13.085" but the can wouldn’t come in contact with the collar after 7.5 turns. Trimmed the barrel down a skosh and I’m now getting 6.5 turns. I know there is 1.7" between the end of the taper and the shoulder. @unclemoak will know the exact measurements.

The first time we tried 1.85" from the gas block to the barrel shoulder based off measurements from a typical 15.1" setup, but then realized it was 0.016" (the thickness of the shims) too long after a little trial and error, so the shoulder was moved back the 0.16" to give 1.69" from the front of the gas block taper to the barrel shoulder.

This is great information. I’ve got the same tapered gas block and entertaining a setup on a shorter rifle gas length system.

I haven’t shot but 50 rounds through it but it seems like a smooth shooter w/ the mid-length gas system on such a short barrel. It’s a solid setup. The can locks up nice and tight to the spikes where on my Mod 1 the can has a tendency to walk off the collar after a mag or two. Almost takes some effort to get it off.

I find it slightly humorous how we both built the same thing, two different ways, and both struggled.
