AAC Brings Back the MPW in .300 Blackout and 5.56 NATO at $999.99 With Six Barrel Lengths

Advanced Armament Company has brought back the MPW, its suppressor-focused AR platform, as a family of complete pistols, rifles, short-barreled rifles and upper assemblies in .300 AAC Blackout and 5.56 NATO, with complete firearms at an MSRP of $999.99 and complete uppers at $749.99, the West Columbia, South Carolina, maker said in a release dated Nov. 10, 2026.

AAC says the line, including the SBR configurations, is available immediately through its distribution network, with availability expanding through additional retail partners. The release adds that SBR sales are subject to applicable laws and transfer requirements, and that all regulated firearm transfers remain subject to federal, state and local rules. Soldier Systems Daily carried the release on Nov. 12.

Every MPW uses an FNC-coated 4150 CMV steel barrel, an AAC ARX free-floating handguard, a full-chrome bolt carrier group with a Carpenter 158 bolt and an AAC BLACKOUT flash hider, which ties the guns to the mounts on the company’s M4-2000, 762-SDN-6 and 300-SD suppressors. Complete firearms also get a two-stage trigger, an ambidextrous safety and Magpul furniture, with final configurations varying by model.

The release names five barrel lengths: a 9-inch .300 Blackout and 10.3-, 12.5-, 14.5- and 16-inch 5.56 NATO versions. AAC’s MPW product page lists six, adding a 12.5-inch .300 Blackout, and gives each a 1:7 twist, the BLACKOUT flash hider and a Magpul MOE SL grip. The 9-inch .300 Blackout and 10.3-inch 5.56 guns ship as pistols with a Magpul BSL brace, and the longer four carry a Magpul MOE SL-K stock.

Barrel threads are 5/8x24 on the .300 Blackout guns and 1/2x28 on the 5.56 guns. The release describes a 13-inch handguard on the 16-inch rifle, while the product page lists 12.5 inches for that model, and the page’s figures are carried in the table. Neither document gives a weight or configuration for the upper assemblies or says which models carry the SBR designation. AAC, part of JJE Brands, developed the .300 AAC Blackout cartridge and says the return of the MPW brings its firearm platforms back alongside its suppressor line, and the product page carries a single $999.99 price with a Find a dealer button as of November 2026.
