BROTHERS IN ARMS M4 A1 CO2 Tactical Air Rifle 4.5MM BB

New in the Borthers in Arms, M4 A1, provides satisfying repeating shots fueled by a single 12-gram CO2 cartridge. Based on one of the greatest weapons platforms ever created--the M4 Carbine--heat up the range with blistering semi-auto shots and unparalleled realism for a tactical experience like nothing on Earth!

Each Brothers in Arms M4 A1 features a full-metal construction throughout the barrel, receiver, and the 18rd BB magazine. Load up a single 12-gram CO2 and start sending BBs downrange at speeds up to 495 fps. Just like the real M4 A1, the M4 A1 gives you a lot of choices for your optics. Shoot straight out of the box with included open sights or remove the rear sights to expose the 5.5" Picatinny/Weaver Rail--ideal for a small scope or red-dot sight. Its adjustable rear stock can be set to your preferred pull length with the press of a button. Each HellBoy is field-strippable, and includes integrated sling swivels for easy carrying options.

If you want a truly thrilling backyard shooting experience, choose the Brothers in Arms M4 A1 and incinerate your targets. (WRITING ON THE RIFLE MAY VARY FROM THE IMAGES)
