The Seekins Precision DMR in 6mm ARC is a no-compromise rifle built for shooters who demand accuracy and reliability in competition, training, and duty use. Built on Seekins' own IMRT-3 upper and SP223 lower receivers machined from 7075 billet aluminum, this 6mm ARC DMR delivers a rigid, repeatable platform that handles the rigors of extended shooting without compromise. The 22-inch 416 stainless steel barrel with 1:8 twist and 5R rifling maximizes the ballistic potential of the 6mm ARC cartridge, making this rifle equally at home on the precision rifle range or in intermediate-distance hunting scenarios.
Ergonomics and shooter control are central to the DMR's design. Ambidextrous controls let you work the rifle efficiently from either shoulder, and the adjustable Seekins low-profile gas block gives you fine-tuning authority over the gun's behavior under different ammunition and conditions. The 15-inch SP3Rv3 handguard runs full-length M-LOK, offering plenty of real estate for mounting optics, lights, and support gear without adding bulk. At 8.2 pounds, the rifle balances firepower and handling—light enough for a day in the field, substantial enough to manage recoil and vibration during precision work.
The DMR comes dressed in black oxide finish with a black Seekins 10X-Ray adjustable stock and polymer grip. The single-stage trigger is factory set at 3 pounds, tuned for clean breaks without unnecessary creep. With a 30+1 magazine capacity, you've got the firepower to work through strings of fire in competition or extended training sessions without constant reloads. This is a rifle that refuses to quit.

6mm ARC is an intermediate-distance rifle cartridge that sits between 5.56 NATO and larger calibers. It delivers excellent ballistics and accuracy at extended ranges with moderate recoil, making it popular for precision rifle competition, training, and intermediate-distance hunting. The DMR's optimized 22-inch barrel and 1:8 twist are tuned to get the most from the cartridge.
The rifle ships with the receiver and handguard ready for optics and accessories. You'll need to mount a scope or red dot separately. The flat-top IMRT-3 upper receiver and full-length M-LOK handguard give you plenty of flexibility for your specific build.
This DMR is configured as a right-hand rifle. While the controls are ambidextrous, the ejection port is on the right side, so it is designed for right-hand shooters.
The rifle is chambered in 6mm ARC. Use factory 6mm ARC ammunition from reputable manufacturers. The 1:8 barrel twist works across the full range of 6mm ARC loads.
