CTM CNC Extended Rail Blast Shield for TM Hi-Capa (Long)

Adding mounting space to a Hi-Capa beyond the limited factory accessory rail has always been awkward — most aftermarket options compromise either on rail length, mounting standard, or compatibility with the rest of the pistol's parts. CTM's Extended Rail Blast Shield takes the proper approach: a full-length aluminium shroud that wraps around the muzzle area and adds Picatinny rail on every meaningful surface.

Top rail extends optic mounting space. Left and right rails accept lights, lasers and accessories. The rear rail offers further mounting options. The detachable lower rail is particularly clever — it gives you a foregrip mounting position if you want one, but unbolts cleanly if you'd rather run the pistol without it. The 28mm inner bore is sized to accept most muzzle devices in the Hi-Capa ecosystem, including the popular Acetech Brighter C tracer unit and CTM's own CNC Compensator.

Compatible specifically with the Tokyo Marui HI-CAPA 5.1 Gold Match, HI-CAPA 4.3 Dual Stainless Custom, and Hi-Capa 4.3 Tactical Custom. The 6061 aluminium construction is CNC-machined from a single piece then post-processed for structural integrity — important for a part that mounts both accessories and a tracer unit and takes recoil loads through both.
