For shooters who demand compact power and modern AR ergonomics, purpose-built AR-style pistols bring a balance of maneuverability and terminal performance. Whether used for close-range defensive applications, brush hunting where legal, or range duty, a thoughtful parts selection and a quality barrel turn a basic build into a capable, reliable package.

17 DESIGN AND MANUFACTURING 17DM-4 is a pre-owned AR-style pistol chambered in .300 HAM’R that arrives as a BUILD with high-quality components and an overall very good condition, though buyers should note a few scratches on the receiver.

Platform and key components

This build combines a 17 Design & Manufacturing 17DM-4 lower with a Wilson Combat 11.3″ stainless barrel, SB Tactical brace, MagPul pistol grip, Aero Precision M-Lok handguard, and a Primary Arms MD-RBG II red dot. The stainless Wilson Combat 11.3″ barrel is a standout element—short enough for a compact profile but optimized to deliver usable velocity from a pistol-length tube.

Caliber: .300 HAM’R — what it delivers

Performance profile

.300 HAM’R is engineered to provide supersonic energy from short-barrel AR platforms. In an 11.3″ barrel it offers extended terminal performance over subsonic-oriented options while remaining controllable in a compact package. That makes this 17DM-4 build a practical choice for users who want straight-line power from a maneuverable pistol configuration.

Optics, controls, and ergonomics

The Primary Arms MD-RBG II red dot is a rugged, fast-acquisition optic that complements the short-barrel profile for target transitions at close-to-medium range. The Aero Precision M-Lok handguard provides modular attachment points for lights or offsets, and the SB Tactical brace helps stabilize one-handed or two-handed shooting. Given the mix of reputable components, this build is ready for modern tactical use with sensible upgrades available if desired.
