Silver Shadow G16556SAB: From the same company that brought you a double-barreled AR15, comes this more normal AR15 that is anything but. A 7075 T6 aluminum receiver set houses all of the Mil-Spec parts on this rifle. This model also features a 15\" 7075 T6 aluminum M-Lok compatible handguard, so mounting all of your lights and lasers is no problem. This handguard features a unique torque bolt compression lock and integrated anti-rotational tabs. As well as a full Picatinny top rail for mounting any optics or night vision devices. The barrel is truly where this rifle shines-a 16\" 416 stainless steel barrel that has been cryogenically treated and features a mid-length gas system. The twist is 1:7, which is proficient at stabilizing all-grain weights. This barrel is also threaded 1/2x28\" and fitted with an A2 style flash hider. If you are a class III fan and want to go through the registration process, this rifle is an ideal candidate and begs to be suppressed with its mid-length gas system. The Gilboa Carbine sinks right into your shoulder with its adjustable carbine stock, while the grip features finger grooves that make shooting this rifle a dream.
