Douglas SPR Stainless Steel Barrels – 16″ & 18″

Designed for precision and built to exacting standards, Douglas SPR barrels in 16″ and 18″ lengths deliver proven performance for serious shooters and clone-correct builds alike. Constructed from premium 416R stainless steel, these barrels feature a 1:7 twist rate, making them ideal for stabilizing heavier, match-grade projectiles with outstanding accuracy.

Both barrel lengths are finished in a durable flat black coating for a clean, professional appearance and enhanced corrosion resistance. The barrels are profiled to the SPR / Mark 12 contour, allowing proper fitment with the Allen Engineering (AE) brake and collar for authentic Mk12-style setups.

A 1/2 x 28 threaded muzzle supports easy installation of brakes or compensators.

Whether you’re building a compact precision rifle or a full-length SPR configuration, these Douglas barrels offer the accuracy, reliability, and pedigree expected from a top-tier manufacturer.
