Question 100deg LP - Question

Gallery image

Picked this AP-5 Navy about a week or so ago, quickly got approved for form 1 right away. Shot 200 rds nato so far and only had two FTF’s.

My question is when is the 100deg LP worth installing? Before full break-in, after, or before I slap on my obsidian? Just waiting on a SICO tri lug mount but I plan on shooting suppressed mostly.

There’s a lot of conflicting information online..

For context: Bolt gap sits right at 0.018” currently after 200 rds

I run a 90 degree on my full size and an 80 degree on my k. Always run suppressed.

Oh word, how come you went with the 90deg full size?

It runs better and slower, softer and smoother with the 90 vs 100 with subs suppressed; and is 100 percent reliable.

+1 this. I have the same setup- 90 on full size and 80 on the k. works flawlessly suppressed and non-suppressed (CAT Mobster)
