Installed a new free float M-Lok handguard the other day and went out to the range to check my zero this morning. Had a sandbag rest and was ready to check.... then.... BRRRRRRRRRRRP!!!!!!
12 rounds out of a full 15 round mag just like that, holy crap!
Never a problem with this carbine ever before after 700-800 rounds or so. No modifications to the fire control group, springs or anything. Totally stock PSA 9mm carbine that I put a MagPul UBR butt stock on and a different M-Lok fore end.
Any ideas on what to look for? I checked that the disconnector is working properly and everything seems to be in order with the fire control. No obstructions in the chamber, gun was clean before firing this morning. What am I missing here? Any help or suggestions would be appreciated!
