B4 SOPMOD (BRSS RECOIL)

The brand-new, patented design of Bolt Recoil Shock System (B.R.S.S) is the first Airsoft electric blowback rifle w/ recoil force equivalent to a gas blowback rifle & stronger that Tokyo Marui&#39s recoil shock system.
 
This system simulates the recoil force of a real rifle by transferring the kinetic energy from piston to the reciprocating weight hammer inside the stock using a high efficient energy transferring mechanism.
 
The movement of the reciprocating hammer creates the “kick” as you are firing a real rifle. Unlike the previous recoil simulating design, the innovative BRSS system is a new and powerful AEG recoil system with countless endurance tests.
 
– Patents Pending in the following countries: Japan, USA, Taiwan, China, Hong Kong, and EU
 – Powerful Recoil – The B.R.S.S. inside provides both high capacity of shooting numerous BB pellets of AEG and powerful recoil characteristic of GBB
 – Low Energy Consumption – The 7.4V Li-Po battery is efficient enough to power up the entire system
 – High Durability – Modify-grade parts packed with powerful motor inside for long durability
 – High Compatibility – Compatible for the original AEG Magazines and over 90% parts are compatible to the original AEG gearbox
 – Auto Firing Rate :8.4V@600, 9.6V@840 Rounds per Min
