Our take:  The B4 SOPMOD CQB, an airsoft version of the M4 MK18 CQB-R rifle, is the compact, CQB legal variant of Bolt’s B4 carbine AEG airsoft rifle.  Featuring BOLT’s renowned Bolt Recoil Shock System (B.R.S.S.), this BOLT SOPMOD CQB AEG delivers strong felt recoil with each shot.  Unlike other “electric blowback” airsoft rifles on the market which only feature cycling bolt covers, this BOLT M4 AEG actually kicks after each shot, providing a heightened sense of realism. With its top-tier performance and added felt recoil, the BOLT B4 SOPMOD CQB is quickly becoming the MILSIM AEG of choice!

Not only is the BOLT B4 SOPMOD equipped with its unique B.R.S.S. recoil system, it also comes equipped with top-of-the-line internal components, such as a high torque motor, precision tight bore inner barrel and steel gear set.  This M4 AEG has been designed from the ground up to be LiPO ready (11.1V Nunchuck LiPO recommended), and has a responsive trigger and a high rate of fire. This rifle comes equipped with a 6-inch full metal quad rail for mounting accessories like laser units and tactical foregrips.  In addition, a six-position crane stock makes it easy to store the recommended 7.4V or 11.1V LiPo nunchuck battery (with 20/25C discharge rate).  Overall, the Bolt B4 SOPMOD Shorty AEG is an excellent choice for CQB gameplay and is already field-ready, shooting under 350 FPS (w/ 0.20g BBs).

Features:
- Built-in Bolt Recoil Shock System (BRSS)
- Full metal receiver and outer barrel
- 6-inch full metal quad rail
- More than 24 inches of combined rail space
- Rotary wheel one-piece hop-up unit
- CNC Machined Steel Spur Gear
- Lightweight CNC machined aluminum piston
- High torque motor
- 6.00mm tight bore inner barrel
- Crane stock w/ rubberized buttpad
- Rear adapter QD sling mount
- Adjustable front and rear iron sights
- Steel birdcage flash hider included
- Shoots up to 340 FPS (w/ 0.20g BBs)

Overall Length:  27.75" in. / 31" in. (Retracted / Extended)

Package includes:  EBB rifle, hicap magazine, steel flash hider, replacement mini Tamiya connector, instruction manual

Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs.  For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs that carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Battery Charger Recommendation:  Airsoft Megastore recommends the use of a universal smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
