Hello all, i'm new to the ar10/ .308 world and was looking for some advice. I have made an ar15 in my past but I know the ar10s are a new ball game! I recently acquired a pre-ban knights armament lower/upper kit and was looking to make a marksman (sniper) rifle out of it. I was looking for your guys input on best barrel for this receiver, best gas block, and best lpk. knights armament unfortunately doesn't sell parts so ill have to make due with after market parts but I'm looking forward to using the knights armament quad rail. I've been told by a few people the sweet spot in regards to weight accuracy and overall function is a barrel in the 18-20" range. so if you guys can point me in the right direction that would be fantastic Thanks in advance for all the replies!!!!
