[QUOTE="Pro2A, post: 1986392, member: 17889"] I'm a "have your cake and eat it too" kinda guy whenever possible. Why not have the best of both worlds......semi-auto fire and bolt accuracy......in one gun. When shooting for best accuracy, I'm not typically going to be needing rapid fire capabilities. USSOCOM has bought into the concept that when shooting ELR waiting for impact to make follow up adjustments allows the running of the bolt and getting back on target to see impact. So, the semi-auto is not an advantage in firepower over the bolt gun when shooting for accuracy at ELR. One of several reasons the Barrett .50BMG semi-auto is being phased out in favor of the MRAD MK22 bolt gun for ELR anti-material role. I install an adjustable gas block on my "accuracy" ARs with easy adjustment....only looking for on/off positions. For best accuracy, turn gas system off. Run as a straight pull bolt action via standard AR style charging handle, or use a side charging bolt/upper design. For fire power, turn gas system on. Easy peasy; best of both worlds. In general a bolt should have more accuracy potential than an AR style due to the true free float of the bolt barrel versus the gas system junk hanging off the AR barrel. Of the AR designs, the Direct impingement has less junk hanging off the barrel than a gas piston system....DI may deliver better accuracy of the two. But, the ON/OFF gas block gets rid of the clickety-clackety slamedy-bangedy of the ON AR gas system. Just a really, really old guy's experience. YMMV. [/QUOTE]
