So I partoke in salad days and bought a mossy ar for $500 bucks about a year ago. They dont really list the specs so I emailed Mossberg ressently because I was curious. Here is the response I got
Thank you for your e-mail. Please see below. The gun is compatible with most “mil-spec” aftermarket components, the Major components are manufactured by Mossberg and or exclusive Mossberg vendors in the USA The receiver (  I think he means bolt) is manufactured from Carpenter 158 steel and is shot peened in a fixture , the bolt and barrel are 100%high pressure tested (HPT) with military M197 or SAMMI equivalent proof ammunition and 100% Magnetic Particle Inspected (MPI), rejection criteria is cracks and inclusions.
The barrel is manufactured from AISI 4140 carbon alloy steel, the barrel is 16-1/4” long and free floated , is chambered for 5.56 NATO and compatible with .223 Rem ammunition , the rifling is button broached wit 6 grooves at a 1:9 RH Twist, the muzzle is threaded with a standard 1/2” x 28” and is fitted with a removeable A2 style muzzle brake not a flash suppressor. Mossberg claims the barrel and bolt are MPI/HPT, yet neither are marked as such. Are all bolts and barrels that go through MPI/HPT marked, is this odd? I also read on another forum Mossbergs response to someones inquiry about the specs and they also claimed it was MPI/HPT Some other things that bother me about the rifle is the non chrome lined barrel, no forward assist, unshrouded firing pin, 6061 buffer tube... But hey it was $500 bucks |
