Revanchist Airsoft takes a look at the Umarex Glock 17 Gen 5 MOS Steel Slide edition made by SRC, detailing its steel construction for key components, smooth slide operation, and the inclusion of four optic plates. While its air nozzle capacity is smaller than some competitors, requiring higher pressure gas, he points out the metallic feel compared to plastic models and its reasonable price, saying its blowback performance is acceptable though with room for improvement.
