Tested 3 AR's that I worked on. Got the 6.5G ejecting at 2 O'clock at about 4 feet with 123gr Black ammo different magazine.. The 224V is ejecting at 2:30 around 5-6feet about,changed the buffer weight. And the 6.8spc is ejecting at 3:30 around 10ft.,changed buffer and spring.
1 in 10.5" on a 21.5" barrel.... Crazy math thing ! Good luck finding one 😁
Seriously .... A 1 in 10 or 11 will be fine. 147 gr through 180 gr projectiles are going to shoot great.
That is pretty cool to watch. My daughter's house is about a mile plus from the end of the runway at Like AFB. On Monday's they do maneuvers. F15's and F35's. Loud as hell !
