I've been a big fan of these cans since I first saw one on a Mk 12 way back when. Haven't seen a thread dedicated to them, so thought I would create one! Anything you spy that is incorrect, let me know.

IIRC, you're talking like $300 additional to simply mount the $600 can on your barrel.

I would agree that if you're not into cloning, MK12 or retro, you probably won't be buying an AE can.

Did you know that nowadays you can use OPS/AE cans WITHOUT doing any barrel work at all? Specific barrel lengths allow you to use collars and have no barrel profiling done...

For instance:

10.5"/7.5" barrels with the spike's tactical low pro gas block/collar combo will mount a suppressor without profiling
The AE m4 adaptor collar AND the spike's LRS collar will allow any government or m4 profiled barrel to use the suppressors without profiling the barrel, too.

If you want to use a FSP rifle, then that's a different story- see my posts two posts before this one.

I paid for Adco to modify my RRA HBAR to accept a 12th model back in the day before all of the new offerings of already contoured barrels. I paid $120, which included the contour and custom collar.

The upper in question:



Mk 12 in progress (mocked up). Barrel will be going to Adco in the next few months for KG coating:

Well, somehow I broke the OP.

I changed 1 thing and suddenly none of the underlining/bolding/coloring is working anymore.

Is there a limit to what you can put in a single post?

The op is pretty lengthy, there are code limits in posts iirc. That's why when people make threads like this they reserve the first 5-10 postings.

In the OP, the Arfmy SF "M40A3" with the OPS Inc can is an M24E2, Can should be a 12th Model .30, not a 3rd model .30

I sent an email to Allen Engineering last week about making a AEM5 in 6.5mm but haven't received a response.  Is there a better way to contact them than via the email address on the website?

He may have been talking about an earlier discussion where someone asked about what was the can on the SR-25.

You can try two things: message their Facebook page (when I've done that, I got a response that day, or email him at: [email protected]. He gave that out in the Blackhawk down thread.

*ETA: 'him' = Ron Allen, the head honcho at AE.

I should have known better than to question Dan.

That is the email address I used and I don't have Facebook.  I guess I'll contact Steve at ADCO and see if he can modify one of his existing cans or reach out to AE himself.

I think that is a non MILSPEC test.

IIR, they meter 96 feet down range.

Lol.

I think you can custom order through Adco, so give Steve a call!

Let me know what he says.

I had to revise my post. I didn't pay attention. Fairly certain that the gun is an M24E2 barreled action (note the long action). The only M24's with OPS Inc cans, is the M24E2, which utilizes the 12th Model .30

Interredasting. Thanks for the info.

Unrelated: but I've noticed that the knurling on the 3rd model has some near the front of the can and others has it nearer to the FSB. Just thought it was interesting. May allow for dating of when they were issued.

For anyone on the fence about these cans and mounts.... DOOO EEEEEET!

I have 5 different 5.56 suppressors and the Ops 12th/AEM 5 sound by far the best with the least amount of POI shift unsuppressed to suppressed. This has proven true on 3 separate hosts with the same can. 2 Ballistic Advantage and 1 Douglas.

Great suppressor, many awesome, huge silence, much wow.

I recently inquired about getting an AEM5 with the knurling, and was told Ron had a couple on hand. Maybe one less now.....

Has anyone else ordered an AEM5 recently, with knurling? Pics?

Unrelated: but I've noticed that the knurling on the 3rd model has some near the front of the can and others has it nearer to the FSB. Just thought it was interesting. May allow for dating of when they were issued.


I recently inquired about getting an AEM5 with the knurling, and was told Ron had a couple on hand. Maybe one less now.....

Has anyone else ordered an AEM5 recently, with knurling? Pics?


I ordered one on the 18th from High Caliber Sales, but I have not laid eyes on it. Form 3 probably won't clear until mid-July.

I'll post pics when I go to fill out the Form 4. I hope it has knurling, but I doubt it.

I went through Kevin too. I had to ask about the knurling specifically, and he made it sound like they're without any knurling unless requested.

Shoot, I didn't even think to ask.

I just shot him an email to see, but I doubt it will.

I almost forgot to ask too! Honestly didn't think they'd have any. I've read (maybe in this thread?) that Ron will make them if requested. Didnt have mine made special- he must've made a knurled batch already and only had a couple left.

Yeah, one of the greatest things about AE is that they seem extremely adaptable to whatever you want.

Pretty much if you want it done and are willing to wait a bit, Ron will take care of you.

That's a fantastic setup!

I hope I can emulate something like that with an AEM2.  What gas block is that?  I was worried about clearance issues with the collar.

Man those are some slick rigs. I've always liked that 11.5 setup.

so for those in the know, what's the chance of the collars working with a standard a2 government profile barrel?

Which collar and who makes the barrel?

The 16th model/AEM4's and lower should work with the standard M4/gov't profile barrel made to the mil standard (such as Colt).

Others are hit or miss.

[Last Edit: JohnStoner] [#39]
With the standard profile you just need the proper collar and you're good to go.

If in doubt Adco is a great source of information.

If you email Ron Allen over at Allen Engineering he should be able to furnish proper OD and length measurements for different barrel profiles and supressors.

I know one or both of them in the past have made custom profile collars if requested.

For either AEM4 or 5, it's a FNH barrel

They have different mounts.

I'm not sure about the geometry of the FN barrel, but I would think it would be good to go?

*ETA: good to go on an AEM4 mount, not the AEM5. AEM5 requires a 'step' (0.750) in the barrel to mount the collar. The AEM4 collar should be able to mount to the step located ~1 inch from the muzzle threads that's already machined into mil-spec M4 barrels.

There's a mount that also uses the USGI step but allows for the M5 to be mounted.

The 16th Model has the same baffle stack as the 12th model.
The only difference is that the 16th can be used on M4 14.5" barrels and still be capable of mounting an M203.







Assuming all the OPS data transfers over since AE took over 100%, I would assume the same can be said for the AEM4 and AEM5

Spike's tapered micro gas block .750:

made for spike's LRS/MRS suppressors as well as OPS INC/AE suppressors to butt up against the gas block.

Really like my AEM5. Got it from ADCO along with the old longer collar.

Don't hate on my non-perfect MK12 clone... Pic was taken when the form came back and I was expecting to have to wait another 2-3 months.

No hate here! Clone looks great. Just needs a Leupy and you'll be good to go!

[Last Edit: SaturationTech] [#47]
Perhaps someone can help me with a question.  I've done a MK12 build, complete with an OpsInc 12th model.  A current project is to build a duplicate of the MK12, but on the AR-10 platform, chambered in 6.5 Creedmoor.  Ops offered the 12th model in 30 caliber, with the same mounting system as the 223 caliber.  The new AE 30 cal suppressor does away with the muzzlebreak.  While not a total deal breaker, I'd like the build to have the 12th model style break and collar.  Other than trying to find an OpsInc 12th in stock somewhere, anyone have any insight in to the best way to proceed?

ETA. Picture of my MK12 in it's current state.  Please excuse the Leupold MK6 on top...

I know I asked about a gov profile barrel, but all I need is that spikes tapered gas block and I can run an AEM4 on a 7.5"? Will it also work for the aem5?

edit: and a compatible muzzle device obviously
