CMMG Banshee Mk10 10mm AR Pistol, 8-Inch Threaded Barrel, Radial Delayed Blowback, Two-Tone, With Primary Arms SLx MD-25 Red Dot
This CMMG Banshee Mk10 pairs the punch of 10mm Auto with CMMG's Radial Delayed Blowback system in a compact, 8-inch AR-pattern pistol. It stands out with a two-tone earth-tone/black finish, ambidextrous controls, and a clean setup that includes a Primary Arms SLx MD-25 red dot, flip-up polymer BUIS, and a Crimson Trace RIG angled foregrip with integrated white light. Presented in excellent condition with an excellent bore, it is a well-sorted example of the Mk10 configuration.

Built on the AR pattern and chambered in 10mm Auto, the Mk10 uses CMMG's Radial Delayed Blowback to manage the 10mm's pressure while maintaining smooth cycling. The 8-inch barrel is threaded and fitted with a removable multi-port scalloped brake/flash hider, and the 1:16 RH twist supports a wide range of common 10mm loads.
Controls are fully ambidextrous where it matters, with an ambidextrous safety selector and ambidextrous magazine release. The upper features an AR-style rear charging handle, shell deflector, and dust cover, with no forward assist. A free-float slick-top M-LOK aluminum handguard keeps the profile clean, with short accessory rail sections added at 12 o'clock for mounting options.
The sighting system is ready to use out of the box: a Primary Arms SLx MD-25 red dot (red reticle) sits on a riser, backed by flip-up polymer front and rear backup sights. This combination provides immediate usability and a straightforward co-witness setup depending on user preference and mounting height.
Finish and markings are clear and correct, including the two-tone earth-tone receivers/handguard with black furniture and the "BANSHEE" script on the left side. Additional markings include the CMMG logo on the left magwell, "CMMG INC BOONVILLE, MO USA" on the right side, and MK10 model marking above the serial area, with selector markings "SAFE/SEMI" on both sides. The receiver and handguard are aluminum, and the pistol wears a textured black polymer grip. Made in the USA.
