Geissele 18” SPR Barrel

Description

$515 CASH Trade Value: $600 Geissele 18” SPR cut rifled barrel in 5.56, includes factory gas block assembly. This barrel is Geissele’s precision-focused evolution of the SPR / MK12 concept, built for shooters who demand repeatable accuracy and consistency at distance. Manufactured from 416 stainless steel and cut rifled, the SPR profile increases rigidity and heat capacity, helping reduce barrel harmonics and maintain point of impact during sustained fire. The 1:7 twist rate is optimized for heavier match projectiles, making it ideal for 77gr and similar ammunition used in precision shooting. Geissele’s Phased Array Gas System with Tri-Port design softens recoil impulse and improves rifle tracking, allowing shooters to better observe trace and impacts during longer engagements. Performance In independent testing conducted by Preston Moore, this barrel ranked at the top of his evaluation, producing some of the tightest groupings recorded in his test set. It demonstrated exceptional consistency and accuracy, performing at — and in some cases exceeding — other premium barrels, including Proof Research and Criterion, within that testing environment. Included • Super Compact Gas Block • Rifle length gas tube • Gas block set screws Ideal For • MK12 / SPR-style builds • Designated marksman rifle setups • Precision AR platforms • Extended-range shooting with match ammunition Condition: New
