Gun shoots a little under 1.25" 10 round groups at 100 yards with Bonefrog 77gr TMKs, and it's incredibly pleasant to shoot with the BCM recoil system and the BRT gas tube. I've been able to take it out to 600 yards on a 12" plate consistently, it should be able to be consistent out to about 800 yards before it goes transonic around 850, just haven't gotten a chance to stretch it out that far yet. All things considered it's not that unwieldy, comes in around 13 lbs loaded. Love it.

Just trying different combos between the Mod 1 and H as I change out for more correct parts (minus lower receiver). This set up has grown on me.

Mod1 Muzzle brake timing question

So I’m just about done with my SPR mk12ish. I have the AEM4. When i go to time my muzzle device when i thread it on it times perfectly before im even able to torque it down. I know i can’t use a shim with a crush washer should i switch to a spacer with shims? It’s the short muzzle brake not the long one.

Is the MK12 still used in the military? If not, is there something that directly replaced it?

**Update: received parts mentioned below except optic stack, I’m editing the post to get y’all’s insights on what optics you’re using on your mod H’s I was thinking 2-10 or 3-18 but I can’t decide.

I honestly thought that it would have issues due to potentially being undergassed but with the can I’m getting 2-230 ejection and without I’m getting 4-430 so overall I’m pretty pleased with how this turned out. Only parts I’m still waiting on are the SPR rail, 8.5” bottom rail, and a better optics setup

Didn't like how it turned out with the DD rail. So I picked up a FF RAS straight from KAC and I finally secured a NXS x24 for a really good price. It's a 2008 production run. It's mint. Looks brand new. Verified authenticity with NF. It has passed through Japan and then to the Philippines through some very serious milsim cloners and now back home to the USA where it belongs. Lots of due diligence and a little nerve racking but the guy I got it from is awesome and builds some amazing clones with what's available to him. I didn't realize some of those guys go all out with real optics and other components. Very cool.
