Just put together a spikes lower with a DD LPK, (the rest of the gun is a spikes upper and BCG with a 14.5 middy DD barrel with DD gas block, standard buffer spring and as supposedly h buffer but no h mark). Shooting PMC .223. Took the gun to the range today and started
shooting and it was on full auto. The longest string of auto I shot was about 7- 9 rounds. Being very confused and questioned by the off duty LEO on the lane next to me, I did a functions check. It was releasing the hammer when I let go of the trigger after holding it down and charging. I took it apart and observing the mechanism it would do one of three things at that point in the functions check. a- nothing, b- release the hammer and c- function normal. I used the search function and couldnt really find anything about this specific problem. and as a note I never had this problem when my other lower was on this gun.
