Ok I am building my 1st AR-15 soon and have decided on a RRA lower. But my biggest problem is the upper!! Can anyone tell me who make's the barrel on the J&T kits and the Del-ton kits? Also are the upper part ie. bolt, charging handle, gas tube, etc. made by the kit company or by a mainstream company like RRA or Stag. So what I want to do is two builds: One will be a gov. profile M-4 A3 upper and the other one will be a 20" HBAR A3 for distance. I would like some info on the uppers. I would like quality parts but I like to build stuff. Any advice on componets that have a good fit and finish. Quality part (Shaw, wilson combat) and dont short stroke. Thank you. |

J&T uses Wilson Barrels but they also sell some Colt barrels based on availablility. I just had a J&T Marksman upper built. It uses a 20" Wilson Premium air guaged Stainless HBAR barrel with 1:8 twist attached to an A-3 upper. I had YHM lightweight handguards attached instead of the more expensive Daniel Defense Rails. It has been pretty accurate so far. It definitely liked Black Hills 68 grain loads (Best 100yd group was .48 inches). I was recently breaking clay pigeons on a berm at 200 yards with Federal Power-Shock 55 gr PSPs with no problem. The upper was assembled shipped and recieved 5 days after I ordered it. (Ordered thursday, at my door the following tuesday). I made it choke once by failing to seat the magazine fully, other than that 100% after 200 rounds. I've only had it 2 weeks, but it hasn't failed on its own. I have a thread with pictures and range report further down here in the Build section. www.ar15.com/forums/topic.html?b=3&f=4&t=323138 |
