Banshee 100 Rifle, Mk3, 308 WIN, NFA

The 100 Series features classic furniture appointments such as the beloved A2 pistol grip and a 6-position butt stock. Chambered in .308 Win, these pistols and SBRs are ready for the range.

The Mk3 platform accepts AR10-style magazines, and is beefier and heavier than Mk4 in order to handle larger calibers. Accepted calibers are .308 Win and 6.5 Creedmoor.

CMMG delivers its lightest and most compact firearms within the BANSHEE line of Short Barreled Rifles (SBR’s) and AR pistols. Don’t let these little guys fool you though. With a wide range of caliber offerings available, there’s plenty of firepower in the BANSHEE line. With a variety of different barrel lengths and furniture to choose from, the BANSHEE 100, BANSHEE 200 and BANSHEE 300 series will have the right combination for you when concealment and portability matter the most.

All Products come with CMMG’s Lifetime Quality Guarantee. ALL NFA RULES APPLY.
