The latest review at the Airsoft & Military News Blog covers the Bolt Airsoft M16A4 BRSS. John writes that... "The 3500g heavy Bolt M16A4 delivers around 382FPS and a rate of fire of roughly 700RPM with a 7.4V LiPo battery. The range and accuracy are very good even with the short barrel thanks to the great gearbox and the tight tolerances.
