Birchwood Casey Duracap Features The Birchwood Casey Duracap Snap Caps are CNC machined from solid aluminum and hard anodized to ensure smooth consistent functioning through repeated use in 7.62x39 rifles. Precision dimensions ensure each snap cap feeds chambers and extracts just like a live round would making them reliable tools for function testing a rifle s cycling and feeding reliability. A durable rubber firing pin impact buffer absorbs the strike of the firing pin protecting it from the damage that can occur from repeated dry fires on an empty chamber. This buffer significantly extends the useful life of both the snap cap and the firearm s firing pin. Laser-marked for easy identification these Duracap snap caps are finished in red making them instantly recognizable and reducing the chance of confusing them with live ammunition. Each pack includes four snap caps enough for most dry fire drills or function checks across a typical range or training session. These dummy rounds are well suited for safety training trigger control practice and safe long-term storage inside a firearm to relieve spring tension.
