New videos and reviews every day 6000+ reviews from our customers The CCK TR 50 conversion kit allows you to transform your HDR50/TR50/TR50L rubber and pepper projectile revolver into a full-size carbine.
The platform is compatible with both first and second generation revolver and requires no non-reversible modifications. For a secure installation, the package includes three plastic brackets (bottom, left, right) that simply need to be fastened with the supplied Allen screws.
Once converted into a carbine, you'll get a number of new mounting systems, such as a 40cm long Picatinny rail for a red dot sight or rifle scope, several M-LOK slots on the sides and bottom, and three QD (Quick Detach) slots for shoulder strap installation. The original underbarrel Picatinny rail on the revolver is still fully functional.
Thanks to the M17x1 muzzle thread with a protective cap, the platform is also ready for the installation of the X-Tracer 50 muzzle flash illuminator, without the necessity of purchasing an adapter.
The stock is foldable without the need of any tools. To release it, it must be lifted up by passing the integrated spring resistance.
Note - this kit does not increase the weapon's muzzle energy. The platform barrel does not directly connect to the revolver barrel, there is approximately a 15mm gap between them. The extended barrel therefore only serves to improve 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.
