    I swapped to the #28 lp yesterday and my bolt gap was still ok. It was at the max allowable space, but it was ok. If you're unsure, it's worth getting a feeler gauge. I ordered one for like $8 from amazon. I don't know what the bolt gap was before I change it.

    Ya i ordered one from amazon as well. i’ve seen almost every person that installed one had the gap be off so it’s good to hear yours worked out. Also with it being at the max space allowed it’s my understanding that this is ideal because over time it shrinks if it moves at all? i could be wrong about that but it sounds like you’re set up is about perfect.

    Does anyone know what locking piece Atlantic shipped with their K version? I left them an email and got a canned reply.

    I have shot a few rounds with and without a can on their unmodified gun. All with 124 gr and it runs fine. But I plan on running a sear and a can with subs and don't want to damage anything.

    My gap now is .017.

    I believe it’s a 110 degree even though the description may say 100 degree. either way it’s def not a 80 degree which is what’ll you’ll need if you wanna run a can and stock especially with 147 grain ammo

    Thanks. I have one coming from RTG as of today. I have a BT stock, a Dead Air Wolf, and a sear. And a lot, a lot, a lot, of time on my hands.

    There were some in stock not long ago. I grabbed one from RTG (Or RCM, I forget but it was one of those two) and had it delivered 3 days later.
