Geissele SPR, Cut Rifled Barrel, 5.56 - 18"

Inspired by the iconic MK12 series, the Geissele SPR 18" barrel is engineered to deliver superior accuracy and performance, making it the perfect Designated Marksman Rifle (DMR) upgrade for your AR15 platform. This barrel is a modernized take on the classic SPR (Special Purpose Rifle) barrel concept, offering cutting-edge enhancements for shooters who demand precision and reliability at extended ranges.

A key factor in improving long-range capability lies in the barrel itself, and the Geissele SPR barrel takes that to the next level. Its SPR profile is designed to enhance rigidity, which dampens barrel harmonics and supports an accurized platform. This also boosts heat capacity, which reduces the likelihood of point-of-impact shifts during sustained fire, and ensures consistent accuracy shot after shot.

The Geissele SPR barrel is made from 416 stainless steel and is cut-rifled for optimized accuracy. The 1:7 twist rate stabilizes heavier projectiles that are common in match grade ammunition.

The patented Phased Array® Gas System utilizes Geissele Tri-Port™ System which softens the recoil impulse and allows shooters to watch trace. This gas system is compatible with mil-spec .750 gas blocks. For optimal performance, Geissele recommends pairing this barrel with a high quality close-fitting gas block. Some gas leakage is normal and will not affect the barrel's function.

Whether you're building a precision rifle or enhancing your AR15 with a high-quality, soft-shooting barrel, the Geissele SPR 18" barrel delivers the accuracy, durability, and performance to meet the demands of serious shooters. Elevate your rifle’s capability with Geissele's commitment to precision engineering and uncompromising quality.

NOTE: Includes Gas Block Assembly (Super Compact Gas Block, Rifle Length Gas Tube, Gas Block Set Screws)
