Volquartsen VC4BT-B Competition Bolt fits Ruger Mark II, III, and IV, Black (DLC)

One of the easiest and best upgrades I have ever done ! No problems after installing .

Much better ejection. It will seriously fling some brass a good distance. Easy to clean with the coating on it and the charging handle is much nicer than stock.

I have a Ruger Mark IV Target with T&J Tactical Integral Suppressor, Volquartsen trigger kit and Vortex Venom. It’s a great pistol but I wanted a smoother operation of the bolt. I read a lot of feedback on this item. There is a slick coating on this bolt that is resistant to accumulation of debris, particularly along the breech face from which the firing pin comes out. Cleaning this bolt is much easier to perform than on the factory stainless. I did replace the recoil spring and rod with my own Volquartsen system since I use a lighter spring for suppressor work. The action of the gun is smooth, and it has been reliable for me. The added feature of the extended bolt makes charging the pistol much easier. Overall, I have been pleased with this, as well as my accurizing trigger kit. My pistol is a Ruger but every other part is pretty much a Volquartsen build. Highly recommend.
