Hello, I’d like to sell my SRS, which is practically new. The entire gun has been upgraded except for the barrel and hop-up chamber. It includes a Faceless bucking, Faceless nub, and Faceless spring guide. The piston is an adjustable Silverback. It comes with a 150 AS Pro spring, and I’ll also include the original spring and a 160 AS Pro spring. The bolt handle grip is Silverback, and I'll add the original one as well. The suppressor is AS Pro with custom foam inside.
The gun comes with everything in the photos is included except for the case.
