DMSR – Designated Marksman Suppressed Rifle

DMSR INTEL:

In almost every iteration of the AR-15, suppression is an afterthought.  The suppressor is simply added to the firearm in the aftermarket environment with little to no consideration during the design, development and manufacturing processes.  With the Designated Marksman Suppressed Rifle (DMSR), we took the opposite approach and designed the system from the ground up for use with a suppressor.
The DMSR shares many of the features of our Designated Marksman rifle, but is a completely different rifle to its core; engineered from the beginning to capitalize on the strengths of a suppressor, and to mitigate the liabilities.   The DMSR is a culmination of everything we have learned over decades of experiences in building, shooting, servicing and manufacturing suppressed AR’s. The development goal of the DMSR was to provide an extremely durable and reliable suppressor-specific system that is also very easy to shoot and very easy to service.
The suppressor-specific engineering of the DMSR starts with the barrel.  Built to our exacting standards, the barrel is purposely profiled to account for the balance of the weapon-system with a suppressor attached, and to manage the additional heat present in a suppressed platform.  The DMSR uses our own gas-port specifications, an individually gauged stainless steel gas tube, and a 4140 billet steel gas block with a Melonite QPQ finish.  The barrel is dual-dimpled for the gas block set screws, and the gas block is also pinned in place.  In the 11.5″ barrel version, a proprietary “CQBR” gas-tube length is utilized creating an ultra-smooth shooting SBR platform.
The BCG is the same top tier kit you will find in our other rifles, built to meet hard-use, high-demand standards.  Individually gauged to meet Mil-spec or better dimensions with a bolt that is magnetic-particle inspected and high pressure tested.  The BCG is DLC coated to provide easy cleaning.
Other suppressor-friendly features include an ambidextrous gas-busting charging handle, concentrically-mounted suppressor adaptor (pinned and welded on the 13.9” barrel to meet NFA barrel length regulations), and an A5 buffer and receiver extension.  The DMSR also features a two-stage match trigger by Geissele Automatics as standard.
The end-result of the design, development, engineering, and testing process committed to the DMSR project is a rifle that exceeds expectations for suppressed AR-15s by running more efficiently, smoother, and cleaner than other suppressed ARs.  The extremely easy to shoot properties of the rifle enhance the experience of the end-user in ways not easily found with other suppressed platforms.  The DMSR exhibits a very smooth recoil “quality” allowing for faster return to natural point of aim, and faster split-times in double-taps and rapid multi-round engagements.  There is also very little gas expelled to the shooter, and less soot accumulating in the system.  Simply put, the DMSR makes the experience of shooting a suppressed platform what it should be – Perfect.
