SIGHT WRENCH FOR AR-15 Reviews & Ratings

BROWNELLS SIGHT WRENCH FOR AR-15

The Brownells Sight Wrench for AR-15 is a precision-machined adjustment tool designed to simplify front and rear sight adjustments on AR-15, M16, and related rifle platforms. Constructed from tough stressproof steel, this specialized wrench provides secure engagement with sight detents for precise zeroing and repeatable sight corrections without damaging the sight assembly.

Square-profile engagement fingers grip sight notches firmly to help prevent slipping during adjustment, while the deeply drilled body accommodates both standard and tall front sight posts. The hex-shaped body provides a comfortable grip for positive control and helps prevent the tool from rolling off the workbench.

Available in A1, A2, and combination A1/A2 configurations, the Sight Wrench allows armorers, competitors, and firearm enthusiasts to make quick and accurate sight adjustments both at the bench and on the range.

Didn't Fit

This AR-15 sight wrench arrived quickly. The wrench seems like a well made item, and was exactly as described - except it doesn't work. I tried multiple times to fit it to the standard front sight on my S&W M&P Sport II AR-15 and it just won't fit. It comes close with a lot of effort, but then it would not depress the sighting button. I've read a lot of reviews of many different sighting tools, and a common thread is that they don't work for one reason or another. I'm going to find a large nail that works, and just use that. One more thing. The tines on the back of the tool stab into your fingers while you're trying to insert the tool in the sight. Very uncomfortable.

Worthless

This is poorly made and would NOT fit the sights of the rifles that I needed it for. found my older cheaper tool and it worked great. glad to be rid of this peace of garbage. Don't waste your money. I wish I had read the reviews before ordering this thing. What a waste of money.

Does not fit

Would not fit A1 rear sight, I will try to file it to make it work, but not something I should have to do.

Absolutely useless piece of garbage

This unit DOES NOT fit a Yankee Hill folding front sight or a Rock River standard A2 - Brownells should list which sights it DOES fit, if any.Besides the fit issue, the basic quality of the "tool" is extremely poor and definately not worth $16.99 - should be more like $2.99. Save your money and look elsewhere - don't bother with this piece of junk!

Dont buy

Bought this to use on the Tech Sights. This tool will not fit in the rear sight holes. The diameter of the pin pattern on the tools is too small. I compared it to another that I have which works on both the Tech Sight and A1s. I have not tried this on an A1 though as I dont own one so it might work on that. Very disappointed. Only reason I didnt send it back is because I need the 5 prong front sight tool.

Worthless trash! Don't waste your money!

As the previous reviewer stated, this piece of garbage doesn't work. The prongs are not long enough. If you've got the right size file, you might be able to get it working, but if you pay [$]for a super simple tool, it ought to work...and if you don't do it just right, you'll simply ruin the tool.How does anyone adjust this sight? Seems like it ought to be easy...hardly. Still searching for a tool that will work without destroying my fifty-dollar tritium front sight.

Great Idea, Bad Execution!

This tool has all the improvments to make it outstanding. It is perfect for me because my AR-15s have A2 front sight posts and A1 rear adjustment wheels. The problem is that the tines or teeth on both ends are not long enough to press down on the spring detents and allow you to turn the front or rear sights. You have to use this tool to turn the post or wheel while using something else to depress the spring detents. The old tool didn't have the cool new look and the ability to put a wrench to it but at least it worked on its own. A simple lengthening of the teeth/tines on this tool would make it an outstanding adition to any AR-15/M-16 shooters tool bag.
