On that 16" rifle gas build shown above I used a crush washer and a couple of the small shims from the PWS shim pack. Got my muzzle break port even with the crown, then I did a 1/4 turn to time the break.

The original Ops Inc instructions that came with my old can, which I still have, say 1/4 turn is the recommendation.

Does anyone have any actual DB reduction numbers with the AEM5? I can’t find any anywhere.

Nearly 40 dB is the number I've always seen in reviews.  I imagine in the real world there are many factors effecting actual results.

Any chance somebody can post pics of groups with the AE/Ops flash hider?

ADCO says they reduce accuracy, I'd be curious to see what that looks like on paper.

What were your groups looking like before the fix? Also, what kind of washer? Crush washer or something else?

Here she is, finished for now. Going to build another lower to dedicate to this upper. Probably stay with some kind of two-tone look. Going to add angled irons and an FDE cloud defense light kit with Streamlight HLX. Likely that new magpul bipod when it comes out.

This is by far the smoothest shooting AR I've ever shot. AAC IBCG, VLTOR A5H2, springco green spring. Criterion 16" rifle-length gas system. Spikes Tactical short collar. Faxon three-screw gas block.

Looks like an integrated muzzle device and collar so as long as the barrel OD isn't too large you don't have to worry about having a correctly profiled barrel.

A word of caution about some of the alternative mounting systems. Make sure the threads and taper angle are correct. Having to warranty a suppressor because  of a someone else's mount error
isn't my favorite thing.

No doubt.  I didn't plan on using it, but figured I'd present it to the group.  The actual "flash hider" is a bit weird for me.

Have you ever made an A2ish version?  I use one of my AEM5s on a bolt gun and the normal brake is a bit much for anyone near me.

Are Daniel Defense barrels correctly profiled? I seem to remember reading that they are. Thinking about turning my 16” gun into a Recce-looking thing but I really like this barrel and don’t want to swap to the BA barrel just for the profile. I’m hoping I could just use the AEM5 M4 collar.

ETA its the 16” middy CHF gov profile

I had a flat milled into the muzzle brake to have it pin/welded. That may be an option if you don’t find one.

Have a smith on my patrol rifle as it rarely gets the can. When I first got it I noticed it would scrape the first baffle. Took it to a local shop that took some material off the end of the tines.

I would expect some more wear on the can.

I have one, and have used it, but don't have it on a rifle currently.

It's a great flash hider but I'm going to stick with brakes in the future.

I remembered Ron saying in the past that he wasn't really able to properly warranty the use of AEM/Ops cans on anything but the Brake mount, as the brake is technically part of the system.

That being said, I'm curious to see what the actual impact to the can's life is with typical non-SOCOM firing schedules, like us folks who go burn a few hundred rounds at the range a few times a year. I want the option of shooting my rifles without the can on and I loathe doing that with a brake. I'm not looking at a compensator like the Spike's either, but what kind of flash hider design would work with the AEM/Ops design without significantly increasing wear on the first baffle? Maybe something with a more closed end? Or does that effectively leave you with a more blasty compensator/brake effect by reducing the area that the blast is concentrated onto the baffle?

Other than the Spikes or AE Brake, I'm only aware of the A1 offered by ADCO and the Smith Vortex that's AE compatible. Currently the can would be on a 16", but in the future I have plans for my 12.5" to have an AEM2 and I want to be able to shoot my SBR unsuppressed without a ridiculous brake rattling my teeth.

Now that I think of it, what about one of those Ops flash hider/brake sleeves that Harms4X copied? How do those work?

I was thinking the same thing. Basically a blast shield to thread on the brake when not using the can.

I have/use the ADCO birdcage on my 26" bolt gun.  I use it in that configuration for PRS matches.  I don't think with that length barrel it's causing any more wear than the normal brake on a shorter barrel.  Most people ask if I'm shooting subsonic, not even kidding.  I love these cans.  This configuration is more accurate/precise than my F-Class gun, but of course the NRA doesn't allow suppressors even though I'd make weight.  

I use my second AEM5 on my MK12 with the normal brake.

I figured the non-knurled would be my beater can from now on, and the knurled would live on the Mod H/SPR and get less rounds.

How plentiful are the ADCO A1s? Are they still making them, how much $$$ are they commanding on the second hand market?

I can't answer any of your questions other than I waited a while for them to be "in stock".  Even then they seemed to run out quickly.  I periodically checked to see availability and will continue to do the same to grab a second.  It's too easy.  No crush washer needed.  Since it doesn't need to be clocked it can simply be screwed on and torqued.

Update.

It looks like as of 5 minutes ago they had 2 in stock.

They now only have 1 left.
