Description

SDIK – Sniper Drop in Kit – a set of components which allows converting a spring rifle into gas-powered rifle. It is cheap and very effective method to upgrade.
The entire structure was designed from the ground up – as evidenced by the patent issued. The whole is based on a simple and effective system of gas supply that is reliable and durable.
With proper construction and materials, the mechanism does not burden other components of a gun – they may be standard (e.g., the trigger assembly, cylinder etc). Rifle can be reloaded with one finger – overcharging is very smooth.
By using an appropriate regulator it is possible to obtain very stable ( plus /-3fps), satisfactory fps.
Using Mancraft regulator provides to continuous adjustment velocity from zero to maximum for the replica (depending on the length of the inner barrel). 
In some rifles assembly may require modification of the body/parts.
