CMMG Adds Sig Owners

CMMG® BANSHEE™ and RESOLUTE® Accept Sig Sauer™ M17™/P320™ Magazines

Boonville, MO – CMMG® spent years innovating the AR platform with the patented Radial Delayed Blowback operating system that has revolutionized the industry. The addition of the Mk17, chambered in 9mm, shows CMMG’s commitment to never settling. Accepting Sig Sauer™ M17™P320™ magazines, the Mk17 is available in both BANSHEE™ and RESOLUTE® configurations. Pair the BANSHEE or RESOLUTE with your existing M17/P320 and you have the convenience of magazine interchangeability.

Staying true to its innovative and industry-leading values, CMMG brings to market the Mk17 on the heels of the U.S. Army and Marine Corps adoption of the Sig Sauer M17/M18 service pistols. In November of 2019, Sig Sauer delivered its 100,000th M17/M18 handgun to the U.S. military and the number continues to rise. Those familiar with the platform now have a personal defense firearm (PDW) at their disposal. As hundreds of thousands of service members adopt a new pistol platform over the next 20-30 years, the CMMG Mk17 will be a great pairing to add to their arsenal.

For personal defense, the Mk17 is offered in the BANSHEE configuration of AR pistols and short-barreled rifles with various barrel lengths. For the competitive shooter, the Mk17 comes in CMMG’s RESOLUTE line of 16-inch barreled rifles.

The BANSHEE is offered as a pistol or short barreled rifle with barrel lengths of 5 inches or 8 inches, while RESOLUTE rifles comes with a 16 inch barrel. Both the BANSHEE and RESOLUTE feature Last Round Bolt Hold Open.

Each Mk17 ships with one 21-round magazine and a retail price ranging from $1,199.95 to $1,549.95 for the BANSHEE and $1,299.95 to $1,799.95 for the RESOLUTE (depending on series).

On all CMMG BANSHEE and RESOLUTE 300 Series firearms, consumers can choose from ten Cerakote colors at no additional cost. Both the 100 and 200 Series offer Cerakote for the complete firearm for an additional $150 per model.
