Update 12/5/2019
I assembled the radiator, flash hider, back plate, and end cap ring on the tapered part of the barrel shroud. Next, I installed the tapered barrel shroud to the transition then I dry-brushed silver on all the parts and attached the Feed operating arm, ejector, and the barrel ends on the sides of the receiver. I used E6000 to adhere the grip scales then masked off the radiator and bolt and applied a weathering wash comprised of black acrylic and light brown. Once this dried, I applied a flat clear coat over the whole rifle.
Tonight, I will complete assembly and this T-21 will be complete. I will weight the completed rifle and report back.
Thanks for the interest.
