SP4™ Extreme Wear Coating Technology is here! Wraith Precision's goal is to go above and beyond Mil-Spec expectations. Wraith Precision’s secret sauce: PRECISION GRINDING. Our BCGs are machined and ground to perform for tens of thousands of rounds. The outside dimensions and ALL three interior dimensions are carefully ground. The Extreme Wear Coating technology, SP4™ is applied to the bolt carrier, bolt, firing pin, gas key, cam pin, extractor, and gas rings. This thin film has the thickness of three (3) microns and a hardness of 3,000 on the Vickers scale. SP4™ advanced surface engineering capability reduces friction, improves wear resistance, increases reliability and is corrosion resistant while extending the life cycle of critical components.

Wraith Precision BCGs with SP4™ Extreme Wear Coating are Polished to a Mirror-Like Finish and are #1 in Hardness, #1 in Flexibility and Elasticity and #1 in Low Coefficient of Friction (.01)
