    Our take:  Bolt Airsoft, well known for their B.R.S.S. (Bolt Recoil Shock System), which simulates the felt recoil of a real firearm, has released their latest M4 Carbine AEG utilizing their popular B.R.S.S. system.  The NEW Bolt B4 LRP features a 12-inch, free float rail system paired with a 14-inch barrel, which makes this airsoft rifle well suited for attaching rail mounted accessories.  Bolt has also included their newly designed BTS (Bolt Tactical Stock), which features ambidextrous QD sling mounts and ample battery space for an 11.1V LiPo battery.

    Internally, the Bolt B4 LRP Carbine AEG utilizes the same high-end components found in other Bolt Airsoft guns, including a CNC-machined aluminum piston, a steel gear set, a high torque motor and a reinforced gearbox shell.  These not only make the B4 LRP Carbine much more rugged than similar AEGs on the market, they also help prevent wear when using high voltage (11.1V) LIPO batteries.  Additionally, the Bolt B4 LRP AEG is equipped with an M120 spring, 6.00mm diameter inner barrel, and perpendicular adjusting hop-up chamber that provides this Bolt M4 AEG with a high muzzle velocity (420 FPS w/ 0.20g BBs) and unparalleled range (250 feet in optimal conditions).

    The Bolt B4 LRP Carbine not only provides some of the strongest felt recoil of any AEG, it also performs better than most other similarly priced AEGs on the market!  If you are looking for that perfect out-of-the-box airsoft M4 that is perfect for outdoor fields, the Bolt Airsoft B4 LRP Carbine is your best option.

    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.
