Well a bit late in the game, but the benefit of others’ knowledge like Tom from MOA Precision, P.E. Kelly, Jesse Tischauser and other 3gunners. Being the frugal person I am, the pump Mossberg 500 served me well in 3 Gun, but just too slow to load at 5+1. I like doing my own work on my firearms when I can. Grandfather was a machinist and I even built a 50 cal handgun barrel in High School shop.
GOAL: looking for a Semi Auto Shotgun, Inertia Drive and at lowest cost but flawless performance.
STOEGER M3000 – Black Synthetic Stock no frills under $500. Add the MOA Precision Extension tube, follower, and disconnector to keep ATF 922R compliant is even needed. With Shipping $127.00

Few other burrs to take care of on the Action Bar. 400 to 800 grit paper. Polish with Dremel.
With a Macro camera what looks smooth is not smooth.
