Seekins Precision DMR 6mm ARC 22" - AR-15 Rifle

The Seekins Precision DMR 6mm ARC 22" redefines what an AR-15 can do at distance. With 6mm ARC in the chamber, it delivers meaningfully better ballistics beyond 300 yards than any 5.56 platform can match.

Built as a semi-automatic AR-15 rifle around 6mm ARC and a direct impingement system, the Seekins Precision DMR 6mm ARC 22" delivers a proven AR-15 experience from first round to last.

Extended Effective Range: The 6mm ARC cartridge maintains significantly better ballistic performance past 300 yards than 5.56 NATO — this is the platform for shooters who need genuine reach from an AR-15.

AR-15 Lower Compatibility: Standard AR-15 lower receivers work without modification. Caliber-specific BCG and magazines are the only requirements, preserving your existing lower investment.

Hunting Viability: Improved terminal energy makes 6mm ARC suitable for deer and medium game at distances where 5.56 runs out of steam — a meaningful expansion of what this AR-15 platform can do.

Precision Potential: The 22" barrel maximizes 6mm ARC velocity and accuracy at the ranges where its performance advantage over 5.56 is most pronounced.
