Wheeler Delta Series AR-15 A2 Steel Front Sight Adjusting Tool (4-Prong)

The Wheeler Delta Series AR-15 A2 Steel Front Sight Adjusting Tool is a purpose-built field tool for anyone who works on AR-platform rifles. If you're installing, removing, or fine-tuning a mil-spec A2 front sight on an AR-15, M16, or M4, this 4-prong tool does the job right—no fumbling with improvised methods or wrong-sized implements. It's machined from steel with a black zinc finish that shrugs off moisture and corrosion, so it'll stay reliable in your range bag or truck toolbox for years.

What sets this tool apart is its simplicity and versatility. The 4-prong design engages the A2 front sight's adjustment slots cleanly, and because it accepts any standard 1/4" hex driver (the kind you likely already own), you're not locked into buying proprietary handles or expensive kits. The integrated key ring keeps the small tool from vanishing in the clutter, and it's light enough to forget you're carrying it until you need it.

Whether you're building a rifle, swapping uppers, or making zero adjustments at the range, this Wheeler tool removes the guesswork and protects your sight from damage during adjustment. It's the kind of unglamorous gear that separates a quick, professional job from a frustrating afternoon of stripped slots and rounded corners.
