So I have a NM M1A that I just bought, and like all my other guns, I like to have spare parts on hand...
Anyone have a list of parts to buy? Are the parts listed at Brownell's decent quality? Any help is appreciated. Thanks! |

Bolt extractor and spring, bolt ejector and spring, bolt roller and clip, hammer, trigger, hammer spring, pins for the trigger group, extra gas piston, gas cylinder valve with spring and pin,extra gas cylinder plug, extra sight aperture, front sight blade,
These should handle 90% of repair problems. If you have the bucks, an extra trigger group, an extra bolt, an extra op rod, all fitted to the rifle. |

Gas piston will wear to the point that the rifle will begin to short stroke.
Same thing happens with M1 Garand rifles, the operating rod head wears down from repeated cycling and heat. Army Small Arms Repair had snap gages for both M1 and M14 gas pistons/op rod heads. If the part didn't pass the go/no-go snap gage test, it was replaced. |
