I have a Rock River Arms 16" "Entry Tactical" upper, no bolt, carrier or charging handle. It is in excellent condition, inside and out and looks brand spankin' new. It's post-ban, but before you click off now, let me tell you about it. It's a flat-top upper receiver, and I installed a detachable A2 carrying handle that returns to zero when you take it on and off. It has R4 handgaurds (one heat shield), but is the size of Colt M4 handgaurds. I installed a small Weaver rail on the lower half of the handguards and mounted a pistol grip on it. There's enough room to mount a light or laser if you wanted to. The front sight base has a RRA-installed side sling swivel assembly, along with the lower, standard sling swivel. The barrel has the M203 step down, too. The A2 flash suppressor is permantly sleeved on the end of the barrel, making it look in profile like a 14.5" barrel, but it is 16" long. The chamber and bore are chrome lined, too. The upper receiver is A2 with a round forward assist and left handed shooter block. The sights, both on the A2 carrying handle and the front sight are sighted in for 100 yards. This upper has NEVER jammed on me...ever. I'll take $425 shipped for the upper and you WON'T be disappointed! I'm sorry, no pics are available, but please feel free to Email me DIRECT at ArmaliteGA@wmconnect.com if you have any questions. Thanks for looking. Kim.
