Blackwater's Iron Horse Rifle, DMR "Designated Marksman Rifle", is a modern sporting rifle with patent-pending LDF "Lever Driven Fire" trigger technology.  How does LDF work? Simple, for the first time, the operator can break shots on an AR-style rifle, using the more dexterous and inline digit, the thumb. The thumb press is more forgiving to trigger press errors and group sizes have been consistently reduced by an average of 26%. Being inline with the firearm means less windage error, add a bipod to further alleviate vertical motion and you'll have your fastest, most accurate follow-up shots, ever... a real coyote-killer, sorry, not sorry Wylie. Built accuracy centric, the DMR's carefully selected components, together, consistently achieve sub MOA performance. The DMR comes with an 18-inch barrel chambered in the proven .223 WYLDE.  The proprietary handguard features m-Lok mounting slots for its entire length at the 3, 6, and 9 O’clock positions, with two QD mounts on each side. This DMR features the FAB Defense RAPS Rapid Adjustable Precision Ambi Buttstock features the Length of Pull (LOP) Memory System that pops the butt-pad out at the exact length you set it at. An integrated cheek rest and ambidextrous design create a comfortable buttstock that you can use for any tactical application.


*Operators will enjoy a consistent sub-half MOA performance with match grade ammunition. (That is < .5" @ 100 yds., snowflakes)
