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

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.
