Description
Anyone running a fixed or backup A2 front sight knows the pain of trying to adjust elevation with a bullet tip, a punch, or whatever's handy in the range bag. The Midwest Industries A2 Sight Tool Wrench solves that once and for all. It's a compact, purpose-built wrench that drops right onto the four detents of a standard AR-15 or AR-10 A2 front sight post and lets you crank elevation up or down with real leverage and zero guesswork.
What Makes the A2 Sight Tool Worth Keeping
The wrench is precision machined from steel, so it holds up to repeated use without rounding off or bending. The square notches engage the sight post detents with a snug, positive fit, which means you're moving the post instead of slipping off and scratching your sight. That tight engagement is the difference between a clean zero and a frustrating afternoon at the bench.
Built for the Range Bag
At roughly 5.3 inches long and well under an ounce, this thing disappears into a pocket, a grip storage compartment, or a pouch on your go bag. The knurled handle gives you a solid grip even with cold or gloved hands, and the lanyard hole lets you attach it to a split ring or keep it tethered so it doesn't wander off. It's the kind of tool folks end up buying a spare of just to stash in a second kit.
Dialing In Your AR Front Sight
Zeroing iron sights is a lot easier when you've got the right tool for the job. Adjusting elevation on an A2 post is a matter of depressing the detent and rotating the post, and this wrench makes that a one-handed, no-drama operation. Whether you're setting up a new build, re-zeroing after a barrel swap, or just carrying a backup for your optic-equipped rifle, it earns its spot. Proudly made in the USA by a company that's built its reputation on solid, no-nonsense AR parts.

Why use this wrench instead of a bullet tip or punch?
