The gauge provides a quick "Go/No-Go" assessment for AR-15/M16 magazine feed lip gap, ensuring reliable feeding and preventing weapon failure.
If the gauge fits through the feed lips, the magazine may need adjustment with the Brownells Magazine Feed Lip Tool or be discarded.
Constructed from 4140 chrome-moly steel, heat hardened for durability and corrosion resistance, with specific measurements for Go: .454" and No-Go: .476".
The tool is designed to fix bent or malformed AR-15 magazine feed lips to prevent feeding problems and jams.
It provides a safer and more precise alternative to using pliers, preventing gouges or cracks in the magazine feed lips.
Constructed with a machined, steel shank and an impact-resistant polymer handle, the tool is durable and designed for easy use.
The M16/AR-15 takedown tools are made of high-impact plastic to prevent scratching or marring the metal of the firearm.
Tools include a pushtool for the takedown pins in two versions: bench and key ring models, and a magcatch tool to ease the removal of the magazine catch.
These tools are specifically designed for the AR-15 and are manufactured by Sporting Conversions, with the takedown pin tool available in black and green.
