ASG Proline Armalite M15 ARMS S.I.R. System M4 Airsoft AEG Rifle

The NEW Proline M15 ARMS S.I.R. System AEG is fully licensed by Armalite, the original manufacturer of the AR-15. From the outer barrel to the buffer tube, this Armalite M15 AEG is made completely of metal! This gives it realistic weight, making it a convincing and authentic 1:1 scale replica. Its main appeal goes to the ARMS S.I.R. rail system, which has been one of the most popular systems used in airsoft and appears in modern first-person-shooter video games. With the advantage of adding additional aftermarket accessories present, you can also add a slew of red dot sights and magnified scopes.

When it comes to internals, a full metal gearbox (with 8mm double bushings and spring guide with bearings) is compatible with aftermarket Version 2 parts, allowing this full metal M4 AEG to shoot up to about 410 FPS with 0.20g seamless BBs. Unlike other front-wired M4 AEGs, the ASG M15 airsoft rifle is equipped with an easy access battery compartment that will fit a 9.6V nunchuck battery, without having to remove the handguard. If you’re looking for a full metal M4 AEG with realistic weight, hard-hitting FPS, and officially licensed trademarks for added authenticity, the ASG Armalite M15 ARMS S.I.R. System AEG is a must-have airsoft rifle for all players!

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 which 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 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.
