The G&P M4 GBB is in all essentialities a WA M4 GBB. But what sets the G&P M4 apart is that although the internals are still WA parts, they are in no way stock. Internally the G&P M4 sports an improved hammer set which featuring a bearing hammer pin set which enables the bolt to cycle smoother. With all other internal parts converted to steel, with the G&P hop-up chamber. Externally the G&P M4 is constructed from metal with an FRP grip, and a 6 position stock. Due to the improved internals and metal externals, the G&P M4 is extremely robust; it also fires with a very heavy blowback and a beautiful and satisfying metal on metal "clack" each and every shot!

The G&P WOC M4 RAS features a very nice M4A1 metal body finished in matte black, complemented with a RAS front set. The original manufacturer markings engraved into the body and the front set looks very realistic. The Military Type Red dot sight complements the G&P WOC M4 RAS, presenting the classic M4A1 RAS Carbine look.
