Spartan Precision Equipment Classic Gunsmith Adapter Features The Spartan Precision Equipment Classic Gunsmith Adapter bonds permanently into a wooden or synthetic stock giving the shooter a completely flush hidden attachment point for Spartan support gear. It is compatible with Javelin and SpringBok bipods Ascent Hoplite and Sentinel tripods SpringBok Quad Sticks and Davros heads so a single bonded installation opens up the entire Spartan lineup. At a total depth of just 0.67 inches it recesses cleanly into the stock without weakening the material or altering the rifle s profile. Because it is a permanent installation it is intended to be fitted by a professional gunsmith or a competent individual familiar with bonding techniques. Machined from hard-anodized 7075-T7351 aluminum the standard Classic Gunsmith Adapter weighs only 0.3 ounces adding virtually no weight to the finished rifle. A brass version is also available for shooters who prefer that material weighing 0.8 ounces once installed. Because the adapter is bonded rather than screwed into a stud there is no visible hardware left exposed on the outside of the stock. For hunters who want the cleanest most integrated way to run Spartan gear on a favorite rifle this gunsmith-installed adapter is the answer.
