CMMG has recently expanded on their MK4 platformed Banshee 300 series of AR-15 pattern firearms with a new 5.56mm 10.5″ barreled variant.

CMMG states “If you want the best an AR-15 has to offer, then the BANSHEE 300 Series 5.56 is your choice.

This AR is fitted with every desired feature including a choice of 10 Premier Cerakote colors, laser engraved model name on the lower receiver, updated ambidextrous controls and sling points, Magpul grip, CMMG’s revolutionary RIPBRACE®, and CMMG’s SV muzzle brake.

Chambered in 5.56, this BANSHEE 300 Series is the shortest 5.56 we have to offer, giving you the mobility you’ve always wanted in the popular 5.56 caliber.

The Mk4 platform accepts standard AR-15 style magazines, and is the most versatile of the CMMG platforms that can utilize all of CMMG’s AR Conversion Kits.

With a magazine change and swapping out the bolt carrier group or upper receiver group, the Mk4 platform can be changed from 5.56x45mm to .22 LR, 5.7x28mm, 9mm and many more.”
