Solved my primer piercing

Written on Oct 22, 2025

I'm using an AR-10 for hog hunting but needed to use non-military rounds which don't have military primers and I was getting a lot of primer piercing, especially with match grade primers. This was happening even with things like Winchester large primers for my 308. Pretty much everything I used at least had cratering or lipping. I tried everything I could think of and even had the manufacturer warranty it but even the new upper from the manufacturer was still getting pierced primers. I broke down and bought this bolt and it fit directly into the AR-10 and I haven't had even primer cratering or lipping since. Recommend 100% to solve your problems before you waste $400 trying to figure out a different solution. This is the best option for fixing primer problems in an AR-10 if you're going to use something other than extremely hard military primers. (PMC x-tac match ammo didn't have primer problems but I wanted a solution where I could use ammo in general instead of one specific brand that can change its primers at any point)
