B4 SOPMOD (B.R.S.S.) Carbine Replica - Black
BOLT B4 SOPMOD (B.R.S.S.) Carbine AEG Replica – Recoil Simulation Airsoft Rifle
Experience recoil like never before with the BOLT B4 SOPMOD Carbine Replica, featuring the revolutionary B.R.S.S. (Bolt Recoil Shock System). Manufactured by BOLT Airsoft (Taiwan), this full-metal AEG offers GBBR-style kick in a fully electric platform—bridging the gap between realism and reliability for demanding airsoft players.
Realistic Construction & Premium Materials
- Aluminum alloy body with steel components: flash hider, magazine, stock ring
- Grainy matte finish and mixed black tones for authentic battlefield aesthetics
- No wobble between receivers – top-tier structural alignment
- Polymer pistol grip, reinforced SF telescopic stock with QD sling sockets
Advanced B.R.S.S. Recoil System
This AEG delivers a noticeable recoil with each shot thanks to a two-part system:
