Sent my Stag Arms 9mm in for jamming problems...here's what they did ti fix it.

Please decode and comment on what Stag did to fix my Model 9L. It reads like they replaced half the rifle.

Testing information: test fired 32 rds
Notes: New feed ramps, BCG, Upper receiver, and charging handle. Once these items were replaced
gunsmith test fired and rifle ran perfectly for all 32 rds.

Sounds like they replaced everything but your barely and flash hider and ground new feed Ramos into your BBC and or the upper. I'd be happy.

I guess, but I think you'd be better off with a fresh probably and hammer next, and drop in a top Juanita on CNN.

That may just be personal preference, though.
