[Available NOW] Gun Power Tool x HRC | Castle Nut Wrench

Some tools you buy once and forget about. This isn't one of them.

The GPT x HRC Castle Nut Wrench is a collaboration between Gun Power Tool and Heavy Recoil Club, two names that take build quality seriously. Whether you're assembling your first AR15-series GBBR or dialing in a long-term project, this wrench makes castle nut work clean, fast, and frustration-free.

Forged from chrome vanadium steel (CR-V), it's built to handle real torque without flexing or slipping. At around 35g, it's light enough to toss in your range bag and forget it's there, until you actually need it.

Small footprint, purpose-built design, and HRC branding on every piece. This is what a proper collab looks like.
