This is the conclusion of my factory Geissele Super Duty short stroking story. The gun had <1K rounds before this happened.

G$ sent me a new BCG after 3 weeks of requests. Took multiple follow up emails & calls before they shipped it. Reasons ranged from man down in CS to BCG being used for a lot of their products & contracts and are hard to source. Gun is working fine now, only use the new carrier and kept the old bolt.

I decided to test the gas key of the defective carrier today to find out why it's leaky. Didn't even take 1min. The 1st screw was free spinning when I tried to tighten it, it was already snapped off. The 2nd screw was tight, wouldn't move at 50in-lb of torque.

Also, the staking is very shallow, no marks on the broken screw at all.

Did G$ use low quality screw? Found it hard to believe for a brand new gun & BCG to have gas key screw shear off within <1K rounds.
