The ARC EDGE is the newest of our comps designed for the FN 509. The EDGE will help you shoot flatter and faster in all situations. We offer our comp threaded in the standard 1/2×28.The EDGE: The EDGE compensator, in the hands of a novice shooter, reduces recoil by 50%. Material: 7075 Aluminum Coating: BLACK Type 3 Hardcoat Anodizing, GOLD Type 2 Anodizing (both 70-73 Rockwell) **Does not fit the compact.** 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.INCLUDED: Compensator Red Loctite Allen Key Set Screws Written Instructions 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.Please note: Adding our compensator to your pistol, in rare circumstances, can effect your reliability and may require some fine tuning. We have ran thousands of rounds through multiple firearms in different set ups with little to no issues, but this does not mean that an issues in reliabilty can not occur. Depending on your existing recoil spring and striker spring, it may effect your slides ability to cycle. Thus far we have not had any recorded issues on tested firearms. We recommend a Qualified Gunsmith install or make any modifactions to your firearm. The Aluminum 7075 compensator will eventually wear out after years of use over thousands of rounds. It depends on the load and weight of the rounds used consistently, but we have built them to last with the best material out there.
