The LWRC IC-MKII 5.56 NATO pistol in Black with a 12.7-inch barrel (brand part no. ICMKIIP5B12SBA3) is the pistol configuration of the next-generation LWRC Individual Carbine. A short-stroke gas piston runs the action, and a two-position gas block set inside the rail lets you choose suppressed or unsuppressed settings. The redesigned MonoForge upper takes an M-LOK handguard, and the SBA3 brace named in the part number rounds out the pistol build. The 12.7-inch barrel gives it a slightly longer sight radius and more velocity than the shorter pistol. It suits range work, training and a compact home-defense setup.

Key Specifications

• The chambering is 5.56 NATO, the standard military round with wide ammunition availability.
• The barrel is 12.7 inches long with 1/2×28 muzzle threads, so a muzzle device or suppressor mounts directly.
• Rifling is 1:7 right-hand twist, which stabilizes a wide range of bullet types.
• The operating system is a short-stroke gas piston, which LWRC designs for reliability in extreme conditions and easy maintenance.
• The gas block is a two-position adjustable A5 design set inside the rail, so you can switch between suppressed and unsuppressed shooting.
• The MonoForge one-piece upper receiver has an integrated rail base and is stronger than a standard-pattern upper.
• The barrel is a cold hammer forged heavy-profile design with a black nitride treatment.
• Back-up sights are the LWRC Skirmish iron sights, which give you an iron-sight option if the optic fails.
• Controls are fully ambidextrous, covering the bolt catch and release, magazine release, safety selector and charging handle.
• The finish is Black, one of the color options LWRC lists for the IC-MKII.
