New videos and reviews every day 6000+ reviews from our customers This conversion kit designated as CCK TR 50 allows you to convert the rubber and pepper projectile revolver HDR50/TR50/TR50L into a fully-fledged carbine.
The platform is compatible with both the first and second generation of the revolver and does not require any irreversible modifications. For secure mounting, the package includes three plastic mounts (bottom, left, right), which only need to be fixed using the supplied Allen screws.
After converting to a carbine you gain a number of new mounting options, such as a 40 cm long Picatinny rail for a red dot sight or riflescope, several M-LOK slots on the sides and bottom, and three QD (Quick Detach) slots for attaching a sling. The original under-barrel Picatinny rail of the revolver remains functional.
Thanks to the M17x1 thread with a protective cap at the muzzle, the platform is ready for installation of the X-Tracer 50 tracer unit without the need to purchase an adapter.
The stock offers a folding option without the use of any tools; to unlock it, it must be lifted, overcoming the resistance of the integrated spring.
Note – this kit does not increase the power of the weapon. The barrel of the platform does not connect directly to the barrel of the revolver; there is a free space of approximately 15 mm between them. The extended barrel therefore serves only to increase accuracy.

It looks great, but unfortunately no one has thought about the function… The
inner barrel of the KIT does not follow the barrel of the HDR/TRK and has a
wider diameter, so if you get even a minimal amount of entanglement, the
projectile starts to bounce around inside the barrel of the KIT and even at 5m
you have a shotgun-like dispersion.

With a matching tuning barrel and sniper kit, it improves the range. Practical
folding stock. Feels well made despite the polymer.
