Stag Arms Chrome BCG
Lower - SAA Lower with generic stock - Can't remember the name. Purchased from a board member
Buffer - Weighed the buffer and it's a standard carbine
Buffer Spring - Assuming it's a standard strength/length.
The only modifications I made are a new trigger guard and grip.
I took it out the other weekend and had issues right off the bat. I could fire the first round in the mag, sometimes two but then it would jam. It would eject the spent casing but not fully grab the next round, catching it right in the middle of the round (should have taken a pic). I had lubed the gun per online instructionals with EWL prior to shooting. I put in a few single rounds and confirmed that it was not locking back after shooting the last round in the mag. I was shooting Federal .223 from the 100 round packs they sell at Fleet Farm.
This may be ill-advised but I shortened the buffer spring from 11.5" to about 10.5" with a bolt cutter and took it back out. I shot thirty rounds and it locked back when the mag was empty. There were no issues on the next 50 rounds but then it started having the exact same failure and wouldn't lock back on the last round.
I don't have any reason to believe that it's gas key. I'm just thinking that I must be losing some gas if I'm using a carbine buffer and a shorter spring and I'm still having the issue.
Would that ammo be considered 'underpowered'? By the end of the day, it had about 100 rounds through it. That shouldn't be enough to get it so dirty it start 'short stroking' again, should it?
Thanks for any help.....sorry for the novel
