ASG - ARMALITE M15 Series M15 Assault SL - Tan is an Airsoft 6mm BB Gun which is an Electric Powered Gun designed and based on the AR15 Carbine, the civilian version of the M4 Rifle, and is fully licensed by ArmaLite Firearms Company. The rifle is primarily constructed from Alloy, with only the Stock, Pistol Grip, Magazine, Rail Covers and Foregrip constructed from High Density Polymer. The weapon is part of Action Sports Games' SportLine Range, making it a great Beginner to Intermediate Airsoft Weapon, but comes with all the bells and whistles of a much more expensive Professional Weapon. The Rifle comes pre-fitted with an Airsoft MOSFET for a better Trigger Response, higher Rate of Fire, and reduced risk of Switch Burnouts, with the rifle being internally wired with High Quality Silver Wiring. Prominently at the front of the gun is the Alloy Handguard, which features full length 20mm RIS Rails, offering users the ability to customise and equip their gun as they see fit, with Grips and Laser/Light Modules. Two Removable Flip Up Iron Sights are provided, however the upper 20mm Rail provides ample space to fit Optics, Scopes and Magnifiers as needed. The weapon features a Rotary Adjustable Hop-Up Unit, which is adjustable for a range and accuracy, hidden behind the Dust Cover. The barrel also features a removable Flash Hider on a 14mm Counter Clockwise (CCW) Thread, allowing the attachment of Suppressors and Tracer Units. This rifle is perfect for those Airsoft Skirmishers who are looking for a great Starter Gun, which also has a huge array of features usually only seen in higher end Airsoft Guns.
