APS Kompetitor C33 Style M4 CQB EBB Airsoft AEG Rifle - BLACK

Like the PR304 series M4, the APS C33 Kompetitor M4 AEG features an electric blowback system and hybrid Version 2 gearbox! But unlike other EBB airsoft guns, this M4 AEG is perfect for the cost-minded player. Even more, it also has a quick-change spring system. This lets you change out the current M120 spring with a spring with different rating to increase/decrease muzzle velocity to your playing style, all without having to take the gearbox apart! The full metal gearbox also features 7mm metal bushings for improved efficiency and durability. This makes it perfect for upgrading your AEG with high-stress parts like pistons, steel gears, and stronger-rated springs. The APS C33 Kompetitor AEG does have a standard handguard, but unlike most airsoft M4s, this APS AEG comes with top and bottom rails with rubber rail covers to prevent rail bit. The retractable LE rear stock also comes with 20mm rails. If you don’t want to spend more than $150 for an AEG with realistic blowback action, a hybrid gearbox, and quick-change spring system without (which is very likely with most AEGs with these features), the APS Kompetitor C33 M4 AEG is perfect for you!

NOTE: This APS AEG rifle does not come with a battery or charger.

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.
