Wheeler 156437 AR Front Sight Tool - Delta Steel Construction

The Wheeler 156437 AR Front Sight Tool delivers precision front sight post adjustment for AR-15 and AR-10 platforms. This specialized tool eliminates the frustration of damaged sight posts and stripped adjustment screws that plague generic alternatives.

What Makes This Different

Constructed from hardened delta steel, this tool provides superior strength compared to standard brass or aluminum sight tools. The precision-machined contact surfaces distribute pressure evenly across the sight post, preventing deformation during adjustment. Unlike universal tools that rely on friction alone, the Wheeler design incorporates specific geometry that matches AR front sight post dimensions exactly.

Key Features

• Hardened delta steel construction resists wear and deformation
• Precision-machined contact surfaces prevent sight post damage
• Compatible with standard A2 front sight posts and gas blocks
• Compact design fits in standard tool kits and range bags
• Knurled grip surface provides secure handling during use
• Heat-treated steel maintains tool geometry under repeated use
• Professional-grade finish resists corrosion and wear

Field use demonstrates reliable performance across temperature extremes and high round counts. The tool maintains consistent contact pressure whether adjusting elevation for competition shooting or zeroing duty rifles. The steel construction handles the torque required for stubborn sight posts without flexing or breaking like softer materials.
