Finally, after a few false starts, we (the Lewis and Clark Shooters Association) have started building some AR-10s for 1,000 yard competition. No pics just yet, but then, there's not much to see so far. Have the uppers and lowers, and a bunch of assorted parts. The barrels haven't been made yet, but that should be in progress very shortly. I think we have one guy who choose DPMS, while the rest of us have gone with Armalites. Being intended for competition under the NRA's Service Rifle rules, these will need to match the Army's specs for their M110s, used in some SDM roles and other specialized applications; 20" barrels, flat tops with detachable carrying handle sights, front gas block and equipped with a four-sided Picatinny railed fore-end, standard GI pistol grip, standard stock and a 4.5 lb trigger. Chambered for the 7.62x51, we're hoping to have these up and running for Perry, 2013. Looking forward to shooting these!
