Being light green in color to aid in better visuals is just one thing that sets this tool apart from others.


GBU, or Gas Block Utility, was created to provide a sturdy and compact platform for users to install/remove gas tube pins on low profile gas blocks, and install/remove gas block pin on the barrel. Machined from a solid block of 6061 and anodized light green, it’s 3.35″ (L) x 2.45″ (W) x 0.94 (H), and it weighs 7.52 oz. The GBU has a light green anodizing. FCD believes colors have a function. They don’t want a black or dark fixture to be used with a black gas block and barrel, where all the colors just blend in and make it hard to distinguish one from another, especially in less than ideal lighting conditions. GBU’s light green color also makes it stand out among other fixtures and armorer tools, most of which are probably all black. GBU’s circular lines below, and rough texture inside the gas block cavity are by design, lest anyone should think they’re tool marks. These take machining time to put in place.  Whereas it would have been good enough to have consistent surface throughout the GBU exterior, FCD put in thoughtful and useful touches. The textures are one of them, the other is the finger access relief access above and below the gas block cavity.

Additional information

* Rebated bottom for using a vise to secure the platform.
* Textured bottom to limit sliding on the workbench.
* Textured gas block cavity to reduce gas block movement inside the GBU.

* Wide gas block cavity allows gas blocks up to 1.19″ long (Crane spec gas block is 1″ long.)
* Gas block cavity is bi-directional, i.e. barrel with gas block and gas tube can be seated on GBU with the muzzle facing left, or right.  Left side accommodates gas blocks with barrels diameter up to 0.855.  Right side barrel cavity is smaller, and accommodates barrels up to 0.760 diameter.
