Maxim Defense Industries is proud to announce the launch of their new direct impingement large frame MD:11 series, a rifle based on the SR-25 cut pattern.

“The MD:11 is an updated variant of the original Stoner AR-10 design. The Direct impingement system still functions like most. There has been no serious change to the inside of the upper receiver; the gas tube forces all that gas into a key screwed atop the bolt carrier group. The gas expands inside the BCG, forcing it backwards into the buffer tube. There is no ‘chamber,’ but more of a diversion like the original design.”

The MD:11 will be available in 6.5 Creedmoor or .308 Winchester utilizing an 18 in. Proof Research carbon fiber or stainless-steel barrel. Using these barrels keeps the weight down to just 9lbs. This weapon was initially designed for United States Special Operations Command (USSOCOM) requirements. However, once the decision was made to commercialize the SOCOM requirement (within limits), 6.5 Creedmoor and .308 Winchester were deemed the best calibers.

It also comes standard with a carbine buffer system, B5 SOPMOD stock, and utilizes the Gisselle SSA-E trigger. Initially, they are available in three colors; Urban, Arid, and Black.
