Independence! The LWRCI SMG .45 Pistol Caliber Carbine is Shipping

    The first batch of the much anticipated LWRCI SMG .45 has shipped earlier this week. Within the next few weeks, more will show up at local dealers.

    These versions all come with an 8.5″ barrel, the SB Tactical SBTi folding subgun brace and two 25-round magazines (or less capacity depending on how much Freedom your location allows).

    I have yet to find a price for this little beast, but you can find a direct link to LWRCI and their SMG45 here. Don’t expect it to be cheap.

    SMG .45 Rolls Out | New Product Announcement
    In Honor of Independence Day LWRCI Ships It’s New PCC.

    Cambridge, MD (July 2019) –  One of the most exciting product releases in LWRCI™ company history is finally here. LWRCI™ announces the release of its first pistol-caliber carbine – the SMG-45. This highly-anticipated SMG model combines the company’s experience on the AR platform with an innovative delayed-blowback/short-recoil operating system to deliver 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™,” says 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 US-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 LWRCI™’s luxury gas-piston AR lineup. LWRCI™’s commitment to craftsmanship and design excellence is clearly evident in the SMG-45: the firearm delivers the high performance that discerning shooters demand alongside the quality and innovation that customers have come to expect from LWRCI™.

    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.

    The first shipment of the LWRCI™ SMG-45 Pistol+Brace production models shipped this week to an authorized LWRCI™ Wholesale Distributor or Premier Dealer with the highly anticipated models showing up at retail starting as early as next week.
