Teru shows how to fit the B&T USW G-17 Carbine Conversion Kit made by Archwick with a G17 GBB pistol... "I made the UMAREX/VFC Glock 17 Gen.5 gas handgun that appeared in the previous video into a pistol carbine. The B&T USW Carbine Kit is a cheaper resin model. The dot sight is from a USP with a standardized exterior and is compatible with real guns, so it should be able to withstand the impact of CO2."
For your next ASMR session with 4UAD Smart Airsoft it's aboutt the Archwick B&T USW-G. This is a fully licensed kit from B&T via ASG that is made by Archwick of Taiwan. This allows the use of the Tokyo Marui Glock 17 or WE G18 gas blowback pistols with ths CCK to work like the B&T USW.
