Manada Airsoft is impressed with the Bolt Airsoft B4 PDW BRSS, particularly its simulated blowback and recoil feature. This 1/1 scale high-performance assembled electric blowback rifle, equipped with the B.R.S.S. system, offers a semi and fully automatic shooting mode. It boasts a stronger recoil, courtesy of the B.R.S.S., and is constructed with a full metal upper and lower receiver. The rifle also features a quick-change spring system and a two-position PDW stock system.
