[QUOTE="Pro2A, post: 2173517, member: 17889"] Are you building an AR because you need to put rapid follow up rounds on target? Guessing probably not, your position is probably not being over run......at least yet. Or, just because you want an AR platform? No wrong rationale, if it meets your preference. The action movement and the gas system....DI or piston......contacting/adding weight to the barrel accounts for most of the AR inaccuracy compared to a bolt gun.....build pieces being of equal quality. Where I and friends just want an AR instead of a traditional bolt gun, I have several times made a straight pull AR bolt gun. Two options: 1) where I want to eliminate action motion for accuracy (and noise reduction), but also want to be able to fire semi-auto on occasion, I run an adjustable gas block....usually only ON/OFF. On for semi-auto; OFF for bolt accuracy/quietness. 2) For bolt only....never semi....I eliminate the gas system/gas block weight/contact for true free float barrel. I like a custom barrel without the gas port machined....always only bolt option. For this always bolt option, I like a side charging upper/bolt carrier design...ala Alexander Arms or others. For bolt/semi flexibility, I run either the side charger or the traditional AR charging handle. The side charger is much more convenient and faster for self spotting impacts.
