we tech open bolt hk416 (m4) gbbr. metal shaving broken nozzle
I got a used hk416. I've been having issues with the bolt carrier group and the plastic nozzle. the bolt carrier group is getting shaved a lot on the left side where the bolt catch is and getting a lot of impact. The plastic nozzle has broke twice in less than 150 shots to the point where i know it is cosmetic so I will most likely just leave it as is.
Does anyone know any issues that might be leading to this?
-I bought it used. All functionned but I didn't have knowledge on the little parts until now.
-I am not sure on FPS but I assume it shot at a proper FPS.
