I built it with Criterion heavy 20" barrel and adj gas block for NRA LR Service Rifle. I noticed that when the gas adjustment is set for reliable operation ( Odin works, 7-8 "clicks" open) I'm showing a forward ejection pattern and slight ejector swipes. With the gas system closed, no signs of excessive pressure or ejector marks noticed. Despite being heavier than my M14, it also has more pronounced recoil impulse.
I had read some stuff about heavy buffers (H or H2) helping these problems, but info is limited. I see some heavy full-size buffers are available but they are not that common. Just trying to see if it's an option or get opinions.
Basic info in case it helps:
Aero Prec M5
Criterion 20"
Odin Works gas block 7-8 clicks open
Aero Prec 308 A2 buffer and spring
Brownell's BCG
M14 Service Rifle load 175gr SMK with 42.0gr IMR4064
