At S3FSolutions, their motto is “Accuracy Matters”, and they mean it. Their mission, simply stated, is to bring barrels to the customer, that are higher quality, more consistent, and cost a fraction of the price.
S3F Solutions accomplishes this by putting every barrel through a rigorous quality control process; to ensure each barrel is as close to mathematically symmetrical as possible, and meets SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) specifications. These fully supported chambers are spec'd for shooting either factory or reloaded ammunition, and are ready to be dropped into your gun and run! We are confident you will be satisfied with your new S3F barrel, because thousands of shooters, from Pro to recreational already are!

About S3F Finishes:
Titanium nitride (Also known as “TiN”, “Tinite”, “TiNite” or “TiN”) is an extremely hard ceramic coating used to improve the substrate’s surface properties.
Applied as a thin coating, TiN is used to harden and protects sliding surfaces, it is applied as a coating of less than 5 micrometres (0.00020 in) and will not effect slide tolerances. Depending on the substrate material and surface finish, TiN will have a coefficient of friction ranging from 0.4 to 0.9 against another TiN surface.
Black Nitride is also known as Ferritic Nitrocarburizing, is a thermochemical surface hardening process that involves diffusion of both nitrogen and carbon into the part. During the process, a two-part surface layer is formed, an outer iron nitride layer with a nitrogen diffusion layer below it. The result of this process is increased wear-resistance, fatigue strength, corrosion resistance, lubricity and cosmetic appeal.
