IWI GAP33SB: The new Galil ACE GEN II is a continuation of the Galil ACE, which is based on the reliable mechanics of the original Galil rifle first developed by IMI in the late 1960s. Drawing inspiration from the legendary Russian AK-47 and the Finnish Valmet RK 62, the IWI Galil family has been continuously improved over the last 50 years, resulting in today's extremely reliable and highly accurate Galil ACE GEN II. Improvements made since the original Galil was first developed and Galil ACE include: Charging handle (reciprocating) on the left side of the milled steel receiver allowing for weak hand operation. Weight reduction with the use of modern polymers. AKM/AK-47 magazine compatibility. Full-length 2-piece Picatinny style top rail. Free Float M-LOK rail forearm. Updated Trigger profile. Updated and shorted safety profile and throw. SBA3 Adjustable Brace
