What’s Included

- 2x 30-round Thermold polymer magazines marked "LAW & GOV'T USE ONLY"
- Smith & Wesson hard case
Built as the Magpul Spec Series, this rifle uses a co-branded Magpul-marked lower receiver and includes a Magpul MOE pistol grip plus a 6-position collapsible stock made from glass-fiber–reinforced polymer. The AR-15 direct-impingement action is semi-automatic with a manual safety and a 30+1 capacity.
The 14.5 in barrel is 4140 steel and is pinned and welded to achieve a 16.1 in overall barrel length. It features a chrome-lined bore and chamber, a 1:7 twist, and a multi-prong flash hider that is permanently attached. The barrel is threaded beneath the pinned/welded device, meeting the configuration noted.
Up top, a flat-top upper with a T-marked Picatinny rail bridges cleanly into the 13 in Troy TRX Extreme free-float handguard, which provides a full-length top rail and circular lightening holes. Folding Magpul MBUS front and rear sights are installed, giving immediate sighting capability while leaving the continuous rail available for additional equipment if desired.
The receivers are 7075-T6 aluminum with a hard-coat anodized finish and include an integral winter-style trigger guard, forward assist, ejection-port cover, and shell deflector. Internals include a phosphate-finished bolt carrier and gas key with chrome-lined interior surfaces. The stock offers a 13.75 in length of pull, and overall markings include SMITH & WESSON SPRINGFIELD, MA MADE IN U.S.A. and MODEL M&P-15. S&W branding is present across the upper and into the handguard interface.
Additional details include the United States manufacture, mfg part number 811024, and two Thermold magazines molded with the period-correct LAW & GOV'T USE ONLY text, aligning with the included magazine notes for this package.
