Can we get a MK12 Build thread pinned??

[Makeshift Mando]

I love seeing all the mk12 post and builds on here. Do you think we can get a mk12 Mod 0/1/H build list pinned thread? When I go over to the bolt action forum there are a few build list pinned and they are extremely helpful and even helped me build my m24. I know there is a whole thread on AR15.com but why not make one here?

Does anyone else think this is a good idea?

I would like one

I still gotta build a lower for this one and get a mk5 or atacr

 

[WillHugh]

This one's a work in process. Have an 18" barrel coming from Compass Lake, and the correct can is still in jail. Planning to build it out like one of the sniper comp MK12s.

Anything about Mk12 you need Q&A, let me know

 

[roostercogburn98]

Thanks for this thread. I don’t have a mk12 build, but always thought the PRI handguard was sexy. Still want to put one on my SPRish build one day. Now it’s on my mind again

Mk12 Grendel with my AEMB in 6.5. Still trying to figure out what to do for a can. I wish I could find an AE30 or get a hold of Ron to make an AEM5 in 6.5 for me.

My mk12 Grendel. I'm missing my AEMB in 6.5, I misplaced it when I put the Sidewinder on. Still trying to figure out what to do for a can. I wish I could find an AE30 or get a hold of Ron to make an AEM5 in 6.5 for me.

These guys may be able to help you:

Sexy. I have to hold off on getting KAC handguards for now since they are OOS everywhere. Settled for Larue in the mean time. But with their lead times maybe I can snag a KAC and cancel haha. My progress so far, Mod 1 obviously lol. Have a barrel on order with Compass Lake as well.

Looks like you've got a good start!

I feel like I read somewhere that they're expecting a batch of handguard soon, but I could be losing my mind. I know the pricing has been updated on a lot of sites, so that might be a good sign. Either way, dont pay the current scalper prices.

 

[cjs88]

The KAC rep I emailed a few weeks ago said they'd start hitting shelves again in like 2-3 months. Emailed them again this week for an update and they said they can't say when they'd be back. I'm on half a dozen email notification lists so when one hits I will drop everything and rush to check out.

Freaking sweet. That NXS looks right and is probably one of the best of the mk12 scopes.

It is amazing, I have the mk4 3.5-10 on my m24ish build and I like it, but this is definitely superior. Just found the swan rail after looking for 4 months lol

You are fucking spot on. I had found a painted one which I was going to use but I found the one mounted here posted randomly last week and grabbed it. Was going to keep the painted one and use it for my nsw recce but just got offered a fa762 for a steal so now Im selling it to free some cash haha

What do you think about the 3.5x10? To me that scope is the most aesthetically pleasing.

for the lack of magnification its actually very nice, very pleasing to the eye, I am just a mag whore lol

I got 3 of these and I'd have to say that they are great if you dont have one you should get one. they are on eBay all the time.

Well now that's just showing off.... excellent taste sir

Seems these guys are making the cans Phil and Ron made. A buddy of mine just ordered one. Should know how they stack up in about 14 months . F’ing ATF…

Trajectory Arms to Produce Allen Engineering AEM5 Silencers -

Allen Engineering's famous Mk12 silencer, the AEM5, is now being produced by Trajectory Arms of Orem, Utah, with exactly the same specs as the original.

Its good that "the torch" was passed on and the mk12 cans will continue to be manufactured. Old ass technology but still quieter that almost all 223 cans of today .

The OCM stuff is interesting too. Adding some lightness on this rig is appreciated. If you don’t want to track down all the ARMS stuff , etc but want the look you could reduce the profile and flute and run the Ti can and save probably 2#.

Edit: fixed my spelling, etc

Admittedly wish i had been a little more patient and gotten a ocm5. 2” shouldn’t make that much different but the mod H feels soooo much more maneuverable than my mod 1 did. So cutting 6oz from it would’ve been appreciated. I’ve got a mark 5 on the way. Think I’m gonna pair it with a griffin sprm and a rds at the 12 o’clock position.

 

[towerofpower93]

I picked up an OCM5 for my Mod 0 build due to the AE cans being OOS everywhere I was looking at the time. While certainly not as clone correct as it could be, it serves the role and looks the part.

Close enough. No one will be able to tell at night and in the rain ..

 

[jdbaum123]

I have both the aem5 and the ocm5, I like them both a lot and honestly can't tell the difference just looking at them, but the weight difference definitely makes a difference with a heavy build

They can be had with the TMR reticle and m5 turrets correct?

They want a million bucks for them! This day and age! 😮

I found a new one with the 223 55gr turret, messaged the person selling it. Found out he was a member here, worked out a deal on here because screw eBay! 🤣 I ordered a 77gr spr turret and good to go! 👌🏽

 

[winxp_man]

Depends on the build you’re going for. For the mod 0’s mildot on the early models, tmr on the late models but non had that I have seen the m5 turret. All have been the m3 at most.

The way I see it some get a little too much into it haha! Especially with what some are asking for clone correct parts! I will post a pic of mine, a mix of PRI and clone correct part. Especially being in Cali! Haha.

If it looks the part in a major way go with it! 🤙🏽

 

[winxp_man]

PRI upper
Arms 40 rear sight
MK4 3.5-10 with 77gr SPR Turret
Arms #22 rings (had to lap the crap out of!)
SSA trigger

Might look for a proper Colt keyhole upper, and Swan #38 spr rail.

 

[smoothy8500]

Quick question on the PRI flip-up sight block with cross screws. How many inch/lbs of torque on the screws to tighten?

I'm not doing a clone or anything just would like one with a TMR and mil turrets or something close to the same size.
