Mancraft is primarily known for their cylinders for VSR that allow you to use either HPA or Co2 in your rifle, and their SDIK cylinder kit is a complete and well-crafted solution if you are tired of pulling the spring.
By installing an SDIK cylinder in your rifle, you gain a very consistent muzzle velocity as well as a very short and light charging handle that makes it easy and quick to send the next bullet towards the target.
All of this comes in a package that is designed from the ground up and patented, Polish craftsmanship at its best.
