Aim Sport Inc. adds AR-15 M4 Platform-specific GAS BLOCK PINNING JIG to its 2016 shooting accessory catalog.

The GAS BLOCK PINNING JIG is an AR tool that is on my short list of “must buy” tools for working on the AR-15 rifle. In fact I have contemplated designing a  similar jig myself. Installing the gas block roll pin is difficult enough. I’m missing a few fingers and that even makes this task more difficult




This new proprietary GAS BLOCK PINNING JIG allows the user hassle free installation of many of today’s most popular Micro Gas Block designs. Anyone who has ever experienced the trials and frustration of having to install a gas tube into some of today’s more popular micro gas blocks will appreciate that this tool was designed to ease their pain.

Designed with both the beginner, novice and the advanced/experienced builders in mind. The GAS BLOCK PINNING JIG  simple-yet-intuitive design is so easy to use even the first-timer will appreciate its convenience, while the experienced builder will find that it cuts down assembly time considerably. Simply put, no matter whether you have just started or have been building guns for years this new jig will become an integral part of your build bench!

This GAS BLOCK PINNING JIG is built from solid 6061 aircraft-grade aluminum and anodized for superior durability and finish. The wide square base design provides maximum stability no matter what your angle of pressure. A well-placed pin allows for easy pin installation and removal. This Jig has been built to work with some of today’s most popular micro gas block designs, like BCM, Rainier, VLTOR and Zero Hour.

Key Specs:

  • Model# – PJGBJ
  • Length – 2¼ inches
  • Width – 2¼ inches

When you consider the features built into this Jig tool one would think it would be priced up with the other higher-priced AR/M4 platform specific tools currently sold in the market. However, as with all Aim Sports products, we are able to utilize our extensive manufacturing experience and resources to kept this Jig tool at an affordable MSRP price of only $30.
