The SPARC compensator, in the hands of a novice shooter, reduces recoil by 50%.

Why use a comp? Easy. Using a compensator on your handgun mitigates the gasses in a manner that helps you run your gun flatter and faster. Dispersing the blast upward and outward is what helps keep your firearm level while shooting.

Our set screw design wedges the compensator onto your barrel, pinching it and keeping it tight during extended use. ONLY SECURE SET SCREWS ONTO THE BARRELS SHOULDERS AND NOT THE THREADING. Depending on your exact barrel, the comp may sit flush to the slide or have a small gap. DO NOT tighten set screws onto the threading, this may cause damage to the threading.

Our compensators are manufactured and anodized in the USA to the highest quality and standard. We use 7075 aluminum for the Sparc Compensator and our BLACK is Type 3 Hard Coat Anodized while our GOLD is Type 2 Anodized to achieve the color. Both meter 70-73 on the rockwell hardness chart. We have had no issue with either coating thus far, but we estimate the black will out last the gold after continuous abuse and use. We recommend you clean your comp when you clean your gun to maintain its luster and finish from corrosion.
