Let me try it on this forum.
I would like to have some machining work done on a RRA upper assembly. It is an A2 receiver, heavy barrel, 16" postban configuration, with no flash suppressor.
I would like to have the barrel contoured to .725" full length, shortened, threaded, and an A2 flash suppressor installed, with a completed overall length of the barrel and flash suppressor of 16" (or just over).
In addition, I may have you swap out the A2 receiver for a RRA flattop receiver.
Please let me know total cost, and I will ship the upper assembly to you.
