Wheeler AR Front Sight Adjustment Tool

The Wheeler Delta Series AR Front Sight Tool is a simple but essential piece of kit for anyone running an AR-15, M16, or M4 with an A2-style fixed front sight base. This four-prong tool is specifically designed to install and adjust the front sight post, allowing you to make precise elevation adjustments during the zeroing process. Each click of adjustment moves your point of impact predictably, making it easy to walk your zero onto target.

Machined from steel with a black zinc finish for corrosion resistance, the tool features a 1/4" hex shaft that accepts any standard hex driver, giving you the leverage needed to make adjustments without damaging the sight post. The four-prong design bites securely onto Mil-Spec A2 front sight posts, preventing slippage during adjustment. The compact size and integrated key ring serve dual purposes: the ring acts as a handle for fine adjustments and helps keep this small but critical tool accounted for in your range bag or toolkit.

For shooters running fixed front sight bases or front sight block gas blocks, this tool is non-negotiable. It's inexpensive, effective, and will last a lifetime. Keep one in your range bag, one in your cleaning kit, and maybe a spare—because when you need it, nothing else will do the job.
