Product Description

The HM Defense Stealth MS3 Integrally Suppressed Rifle is a top-of-the-line firearm with superior accuracy and innovative features. With a patented barrel featuring an integrally machined MONOBLOC gas block and suppressor, a custom 10-3/8" inch free float 1913 Picatinny rail, and Mil-Spec forged 7075-T6 upper and lower receivers, this rifle is built to perform. Complete with Mil-Spec components, an enhanced grip, and a black CERAKOTE finish, this rifle weighs in at 7lb 14oz (without magazine).

This rifle is designed to deliver superior accuracy and performance in a compact and sleek design. One of the standout features of the Stealth MS3 is its patented barrel with an integrally machined MONOBLOC gas block and suppressor. This innovative design allows for a more streamlined look and feel, while also reducing recoil and muzzle blast.

The barrel is chambered in 300 Blackout, which is an excellent choice for a suppressed rifle. The 4150 Chromoly barrel is 16.25 inches OAL (9" inch barrel with 7.25" inch integral suppressor), features a 1:7 twist ratio and a pistol length gas system. All HM Defense barrels are match grade and button rifled for superior accuracy, making this rifle an excellent choice for precision shooting.

The custom HM Defense 10-3/8" inch, free float 1913 Picatinny rail is CNC machined from 6061-T6 aircraft grade aluminum. This rail is compatible with the popular Magpul M-LOK mounting system, allowing you to easily customize your rifle with accessories and optics.

The lower receiver is a Mil-Spec Forged 7075-T6 Lower Receiver with Type III Class I hard-coat black anodized finish. This lower receiver is built to withstand the toughest conditions and provide reliable performance in any situation.

The upper receiver is also Mil-Spec Forged 7075-T6 M4 Upper Receiver with Type III Class I hard-coat black anodized finish, M4 Feed Ramps, and a 1913 Picatinny rail flat top. This upper receiver is designed to work seamlessly with the lower receiver and provide a solid platform for your optics and accessories.

The components of the HM Defense rifles include a M16 bolt carrier group with patented HMB bolt and Mil-Spec components, including the trigger and fire control group, charging handle, and buffer tube/spring. The custom Trigger Guard and Monobloc Dust Cover add an extra touch of customization to this rifle.

The HM Defense rifles also feature a custom Quick Disconnect (QD) end plate, which allows you to quickly and easily attach and detach your sling. The black Mil-Spec HM stock and enhanced grip provide a comfortable and secure grip, while the included magazine ensures you're ready to go right out of the box.

(5 out of 5) Most innovative 300 blk
by from Dayton, OH on

They thought of everything on this boomstick! Going from supers to subs with no tuning is a game-changer. For the first time, I feel the 300 is not only duty-capable but is now my go-to platform. This thing eats every possible ammo type and weight. I have found with zero malfunctions in over 5000 rounds.

(5 out of 5) Unmatched reliability
by from Mason, OH on

Whisper quiet performance with subs. One of the few platforms out there that will reliably cycle virtually any kind of 300 ammunition. You can reliably switch ammunition types back-and-forth without any need of adjustments or concern.
