This Spike's Tactical LE model short barrel rifle features an 11.5 inch cold hammer forged barrel made by FN America and a carbine length gas system with an A2 front sight post. It is chambered in 5.56 NATO with M249 SAW spec chrome lining to last thousands of rounds even after long strings of rapid fire. The light weight profile reduces weight near the muzzle making it more pointable and easy to shoot. While it does have a 9" quad rail handguard, the short barrel and the short length of the handguard bring the weight closer to your body for less fatigue when aiming. Additionally, the BAR2 quad rail free float handguard offers a rock solid platform for attaching lights, grips and mission critical lasers. If you are looking for a duty ready 5.56 SBR, you can't go wrong with Spike's Tactical.
