問題兒童問問題:
粗槍管較耐熱...如果一支AR步槍採用幼槍管,會否在持續快射模式中 因升溫而很快便變得失準?
Yes, the barrel expanded. Each firing pressure have greater different. More Variable = Non consistency.
When your cold AR barrel is 3/4 moa at 100 yards, you rapid fire for 200 around. Your AR barrel might shooting 2.0~3.0 moa at 100 yards before you cool it down again. That's only my estimate. i might be wrong.
