Gun and gear reviews MK-15 is peak

Absolutely in love with this thing. 500 rounds yesterday with out issue (I know it’s not a lot)

only thing is it’s stiff for about the first 20 rounds. The bolt wouldn’t close on 5 rounds. So shot 5 4 round mags then it took full mags no problem. The bolt would also close at first on the empty mag like it had another round to go. (Only happened on first 2 mags) believe it was also just because it was stiff. After it loosened up It was smooth sailing. (Give your rifle a chance to loosen up a bit and don’t immediately think it’s fucked)

Also takes the crossmags no problem.
Very well built rifle though. All metal parts including the stock.
QC issues have all been fixed from what I can see (charging handle digging in, etc)

What's the accuracy like, did you do any testing at 100m?

1.25moa for a duty rifle is fantastic. Now only for it to actually cycle.

Yeup was a bitch to get it cycling, but I got mine running slick as pig shit. Has been a riot after the initial headache

What'd you do to get it running? I heard guys were cleaning out the gas block extensively and cycling the action like 100 times before hand

Started with just trying to rack it a bunch with no prevail ended up running a small amount of valve lapping compound on the high friction areas between bolt group and upper and racking the ever living piss out of it to polish out contact spots. Has run mint since. Ive been talking with 313 operator and I believe he is going to be making a video addressing these issues and my fix aswell

Neat! What are the high friction areas you noticed on it if you dont mind?

I imagine it'll be different gun to gun. I sooted the fuck outta the bolt with an oxy torch (not putting heat to it) just using the black soot. Cycled it and anywhere the soot was worn away I added lapping compound after cleaning the soot off
