Billet Ruger Precision / American Rifle Cocking Piece

(5 reviews) Write a Review


*NOTE* This firing pin back is not compatible with RPR/American rimfire rifles or the RPR magnum rifles.


This is a billet RPR/American Firing Pin Back or cocking piece developed by AD Arms in response to the breakages many have experienced with the factory MIM part.  This is designed to be a direct, drop in replacement for the factory piece which will not be susceptible to the typical breakage. 

Machined from a solid, pre-hardened 4140 alloy billet, this is then nitrided for increased surface hardness, wear resistance, corrosion protection, and to provide a deep black color.  This fully machined part will get the job done without risk of failure. 

Furthermore, this part is lighter than the stock part so it can also increase lock-time performance all while being harder which decreases cocking effort.

    Superior replacement part. Bolt runs smoother and has less lift after shot is fired.

    Excellent product! I've yet to shoot with it on but just installing this part dropped my trigger pull weight by 1/4 lb and it functions MUCH more smoothly when cycling the bolt, the bolt closes a lot easier with this cocking piece installed! The craftsmanship on this product is superb!

  • High Quality Part!

    I ordered this part to replace the OEM MIM part. The replacement piece is well machined and nicely coated. Once installed on my RPR, did a lot of dry firing prior taking it to the range. It worked flawlessly and I noticed the bolt jump when dry firing on an empty chamber, is significantly reduced. I’ve only shot 20 rounds since installing, doing load development, but so far, the cocking piece has worked well with no malfunctions. Extremely pleased with it so far. Given the quality, I expect the part to hold up well. I highly recommend!
