American Tactical Imports brings us a lightweight AR-15 carbine based on their populat OMNI polymer lower receiver. The heart of the rifle, a 5.56 chambered 16" M4 profile barrel, is finished with Melonite for extra long life, superior corrosion resistance, and a little extra velocity. The Gas block features a picatinny rail on both the top and the bottom, allowing for easy installation of sights, bipods, and slings. The fixed M4 style stock means it'll have that classic carbine look.

"The exploded view showed a 30 Rd Mag and a gas block with rails on top and bottom. Also the fixed stock was shown all the way near the \"Lower\". When I received the weapon, it had a 10 Rd Mag and the Stock is stuck all the way extended \"AWAY\" from the \"Lower\". I don't understand this other than the weapon was an \"OLD\" item that CTD purchased that was scheduled to be shipped and acceptable somewhere in NY. Otherwise, it appears to be well done, although I haven't fired it yet and am wondering what kind of Bolt Carrier it has in the \"Upper\". An M16 Carrier and guts, or an AR 15 Carrier and it's Guts? Still good price."
