I have a gen 2 little bastard for 6.5 but want to move it to my 223 but not sure if I’ll have any issues. Thought I’d check with the experts before I made the move...thanks!
In this article they tested whether caliber size actually makes a difference on muzzle brakes. Makes almost no difference if you are using the specific caliber vs a larger one.
I found a deal on a gen 2 in 7.62 so I picked it up. Running it on 6.5 and 6mm. Youre going from a .264 to a .223 so you're talking a very small difference
