First time at the range. Used Am Eagle FMJBT 223 rds.
Fired @ 50 rds in singles using DPMS 10rd and Colt 20rd mags, barrel conditioning. Bolt not locking back.
At @ 50 rds, loaded DPMS mag with 2 rds, on firing the bolt road up over the second rd, denting it. Cleared it and tried a Colt mag. Same results.
Fired @ 200 rds, all singles, bolt never locked back all day.
Get the feeling the bolt not going all the way back, something restricting it, loses momentum.
Noticed the cam pin is very tight in the race, does not move freely, even after liberal lubing.
Am I experiencing the results of a new, tight weapon, & parts need to break in?
