LWRCI has released its first pistol-caliber carbine, the SMG-45. This SMG model combines the company’s experience on the AR platform with an innovative delayed-blowback/short-recoil operating system that delivers a unique pistol-caliber carbine shooting experience. 

“We listened closely to shooters, operators, and customers throughout the development of this exciting new platform for LWRCI,” said David Ridley, senior vice president of sales and marketing. “The SMG is truly a ‘Step-Up’ pistol-caliber carbine that offers our customers innovative features and comfortable ergonomics in a compact package.”

Built from the ground up around U.S.-manufactured UMP magazines, the SMG-45 is a completely new PCC in .45 ACP that features many of the same controls and performance attributes found in LWRCIs luxury gas-piston AR lineup.

 

Constructed of advanced aluminum and steel alloys and protected with hard-coat anodizing, ferritic nitrocarburization, and nickel-boron surface treatments, the SMG is built to last. Features on the SMG include a signature fully-ambidextrous lower receiver with AR-style controls for the safety and bolt catch/release, a paddle magazine release, the LWRCI Ultra Combat Grip, and an LWRCI Enhanced Fire Control Group. The upper includes an 8.5” cold- hammer-forged CrMoV steel barrel, LWRCI’s familiar Modular Rail System with LWRCI™ Rail Panels and Hand Stop installed at 3/6/9 o’clock, Magpul MBUS Pro sights, and more. The launch configuration for the SMG-45 is a pistol equipped with the SB Tactical SBTi folding subgun brace. The SMG-45 ships with two 25-round magazines.

To coincide with America’s Independence Day the SMG-45 Pistol+Brace began shipping on July 2, 2019.  For more information, visit lwrci.com.
