Gas Block & Gas Tube Roll Pin Tool Jig — Bench-Friendly Precision

Make gas block and gas tube pin work faster, cleaner, and safer with the Bunker Prints Gas Block & Gas Tube Roll Pin Tool Jig. This purpose-built jig holds your gas block steady while you install or remove roll pins, reducing slippage and minimizing the risk of marring parts during gunsmithing tasks.

Designed for the working bench, the jig streamlines repetitive pin work and protects your components — a small investment that saves time and headaches on every build.

Why You’ll Like It

  • Stable, repeatable positioning for precise roll-pin installation and removal
  • Recessed pin-catcher area collects removed pins so they don’t roll off the bench
  • Integrated spare-pin storage keeps replacement pins close at hand
  • High-infill 3D print pattern for exceptional strength and durability
  • Designed to fit most .750 low-profile gas blocks
  • Made in the USA — designed and manufactured by firearm enthusiasts

Fitment & Compatibility

Designed specifically for most .750 low-profile gas blocks. If your gas block is significantly different in dimension or an oddball aftermarket design, double-check fit before installation.

Materials & Construction

Printed from high-strength, impact-resistant polymer with a high-infill pattern to resist deformation during pin installation. The geometry is optimized to absorb hammer or punch forces while keeping the gas block aligned.

Usage & Safety Notes

  • Intended for use with hand punches and light hammer taps. Avoid excessive force.
  • Use eye protection and bench clamps as appropriate — pins can spring free when driven out.
  • Do not use power tools (impact drivers, pneumatic hammers) directly on the jig — hand tools only for best results and longevity.
  • Test-fit the gas block in the jig before any final pinning to confirm alignment.
  • No firearms, barrels, or gas blocks included — this listing is for the jig only.

What’s Included

  • Gas Block & Gas Tube Roll Pin Tool Jig (one piece)
  • Integrated pin-catcher and spare-pin storage (built into the jig)

Built for the Bench

Whether you’re a weekend builder or a professional gunsmith, this jig makes pin work simpler and more predictable. Keep one on every bench — it’s the small, practical tools that make the job feel professional.

Designed and 3D-printed in the USA
