Hi all, I've been using the Tromix linear comp on my Ruger AR 450 Bushmaster and really like it, so I got one for my 7.62x39 AR Pistol.
I've been getting some erratic accuracy with most of my loads lately.
Tonight I pulled the comp apart to clean it and was very surprised at what I found.
The screw in insert somehow got compressed and pushed forward.
I'm thinking that maybe it wasn't heat treated correctly.
