The Brain Exploder puts the Silverback Airsoft SRS R-Hop and Tightbore to a test in his latest video... "After initially testing the rifle for range I was satisfied with it but thanks to a YT viewer of mine by the name of Koree I was swayed towards installing a tightbore ZCI inner barrel (550mm) and the R-Hop mod with some supplies from Clandestine Airsoft and McMaster-Carr. Check out Koree's SRS guide for more information on this mod and others available for this rifle, big thanks."
