Im starting a new light(ish) build & have narrowed my bolt carrier to a JPEnterprises LMOS Al or the Whiskey Arms Al carrier.
Besides an adjustable gas block, what should my gas system length and buffer system consist of?
Also I do understand that Al carrier are definitely not for duty use and wear much faster. How many rounds should I expect them to last?
