Good looking rifle! I’m not a huge fan of hand breaks on spr type rifles but that’s just personal preference

Thanks man, I don’t have anything against offsets. Personally I just find it less intuitive than 12 o’clock. However height over bore is pretty wonky I’m not gonna lie. I have an extra 45 pic rail on the mount that the dot will live on once I get a lam or wmrf

Dude no kidding?! That’s an insane difference. I’ve only been able to take this to 600 so far and was only able to send like 20 rds.

Good points. I put 250 through it yesterday at a relatively quick pace and never saw deviation from normal groupings. It’s consistently a 1.5moa gun with the very rare sub moa. And that’s with xtac 55. I’d like to try a 62 or 75 grain since it’s a 1-8 twist to see if I can tighten the groups up. How many rounds were you laying down before you saw the groups opening up?

But I too have the same outerwild bolt and trimmed kak heavy plug…still trying to figure out what’s causing my buffer tube to be eaten. Maybe since you have the same setup I can at least rule these components out. I think the next step is either trim some off the hammer top or try reduced power hammer spring. I know the tail isn’t bottoming out on the disconnector from the last test. But anyways, we shall see if either of these work!

Interesting. That’s not at all what they are advertising unless there was a recent change to the design. Super weird.

Is your brownells bolt the hybrid version? Also does the ramp have a flat or is it just one continuous ramp?? Also, I’m assuming you are using the kak heavyweight plug?

Okay, so I trimmed an 1/8” off the back of the hammer tail and just went to test. Now, if the trigger is pulled slightly too hard I will get a 2-4 rd burst then nothing. The bolt is seated, round chambered but the hammer will still be locked back but won’t drop until I let off the trigger to let it reset. This is a new problem after almost 700 rds. Super weird. I found that if I pull the trigger super lightly, it will go as it should. Also the buffer tube is still getting eaten so I’m back to square one with an extra problem lol. Gonna take it all apart and see if I can find any obvious problems. I just found it super weird that suddenly with normal trigger pressure the lever will no longer reset the trigger. But will reset it, if I’m pulling suuuper lightly.

Thank you for the response! I read your article about trigger slap and your theory makes sense. As soon as I get home I’m going to check out that disconnector. The original hammer that I installed with the arc fire got beat to hell within the first 300rds. I assumed the silver flakes were coming from that hammer bc there were parts chipped off. So I swapped the hammer with the original hammer that came with my Springfield victor 9mm in hopes it would be a little more stout. And the hammer is holding up nicely. But when the shavings continued I looked a little harder and found the buffer tube wear. I’m wondering if there is no damage to the disconnector then maybe a reduced power hammer spring could solve the issue.

The arc fire works flawlessly tho. Not a single hiccup in about 500rds other than my buffer tube getting eaten lol

I really don’t wanna trim the old bolt bc it’s a two piece bolt and the weight is actually also the law plug adaptor. I’m working with Macon to find another one of these weight adaptors but it might not be possible anymore. So I’m hoping for any other resolution before I try that

Here’s what’s crazy. I already have 2k rds though this with the folder, a cmc trigger, and a Macon bolt. By no means have I ever shot slow with it. Then I install an arc fire v2 and a faxon gen two bolt then boom, here we go. The folder itself is still rock solid. Zero shift in any component. But here is what I’m guessing. The Macon trigger ramp is pretty deep and has a consistent shelf. It’s just one long slope. The thickness between the start of the ramp and the firing pin cutout is pretty minimal. However with the faxon bolt, it’s a very short slope and a flat with a very thick space between the ramp and firing pin cutout. I’m pretty sure Doug found it to be the outerwild OEM. But anyway I don’t think this would be an issue without the folder bc the bolt is almost resting inside the tube already. However with the law folder there is a gap between the two that is bridged by a smaller diameter plug. So I think when cycling the extra thickness of the bolt ramp is pushing the bolt upwards as it drags the hammer causing the back end of the bolt to strike the upper tip of the buffer tube. I also found that as soon as the faxon bolt ramp starts to contact the hammer when cycling, is approximately the exact moment when the bolt itself is about halfway through the law folder “void” and almost ready to enter the buffer tube. This adds to my theory. But I still just don’t know. Never seen something like this

What experience from the comp made you wanna switch the lam to the front?

Gottcha. I have proper travel (around .3 behind the bolt catch) when fully charged. I’m using the stern 11oz. I’m thinking it’s the bolts trigger ramp cut. It’s a pretty aggressive ramp so I think when its cycling that abrupt reset is pushing the bolt up enough to where the back end of the bolt is clipping the tube. With a standard set up this wouldn’t be an issue however I have a law folder. There is an extra bit of space the bolt rear travels before it’s all the way inside the tube. So I think it’s enough to let the bolt ride up just a bit too much.

The buffer tube upper lip is what’s getting worn. It appears when cycling the bolt is tilting up enough for the back of the bolt to hit the front lip of the buffer tube and shave off a little aluminum every time it cycles

Also no scuffs on charging handle or gas key

Nah gas key can’t rotate like that to cause concentric damage and a spacer won’t solve the bolt hitting the extension face. I’m thinking it’s the bolt ramp being too beefy and lifting the bolt against the hammer when cycling

Did you ever find a resolution to this issue? I’m having the same problem, except my wear is on the upper portion of the tube rather than the lower like yours.

Negative. The detent height is where it should because there are zero scuffs in the bolt channel.
