Shipping for firearms is always $9.99 to lower 48 ArmaLite is proud to announce its AR-10 Law Enforcement Carbine. ArmaLite has long been known for its LE carbines chambered in .223/5.56X45mm NATO. Now comes an LE firearm with the added stopping power of the .308 cartridge. ArmaLite's AR-10 Law Enforcement Carbine brings an LE firearm with the added stopping power of the .308 cartridge. The AR-10 LE Carbine sports an innovative A2-style front sight designed by ArmaLite's engineers and is manufactured from forgings here in their factory. It is taller than traditional A2 front sights to account for differences in AR-15 and AR-10 receiver heights, eliminating zeroing issues when a carry handle or flip up rear sight is used in combination with an A2 style front sight on this .308 platform. Combined with the A4 flat-top upper receiver popular for its ability to accommodate sights, scopes, lights and other LE accessories, the result is a spectacular ArmaLite .308 carbine ready for the toughest LE duty. The 16" barrel is chrome-lined chrome moly. The rugged Troy Medieval muzzle brake enhances control and accuracy during rapid fire. It's tough enough to serve as an improvised breaching device if the situation calls for it. The Ergo F93 buttstock features a fixed cheek piece for a constant and repeatable cheek weld in any of the eight available stock positions. Once the buttstock is locked into position, the F93 is as rigid as a fixed stock. With a completely adjustable 4" length of pull, this stock gives the shooter plenty of room for fine-tuning the stock to their liking. Caliber: .308 / 7.62 X 51 MM NATO Barrel: 16" Double Lapped, Chrome Lined/ Chrome Moly Rifling Twist: RH 11:25"
