Model 15 M4 A1 Rear Sight A2 Front Sight Adjustment Tool by FSI

Handy tool if you are shooting standard M16 style sights. This makes sight adjustments much easier than any other method I have used. The only down side is it might not work on all aftermarket sights. The front sight adjuster is not long enough to make adjustments on the HK style front sights from TROY for instance, but for standard style sights this tool is great.

I feel compelled to write a review. If you have a daniel defnse A1.5 fixed rear, this is the tool you need. Works perfectly if you have a fixed sight base A2 front post and the fixed DD rear sight. It fits inside a Magpul MOE grip as well.

For the price it was worth it.. Hard to use but did the job..

The tool that was sent to me was a 5 prong A1 adjustment tool, not an A2 as specified in the listing. I contacted the seller and they said they do not carry any 4 prong front sight adjustment varieties. The rear sight adjustment works fine, can't say anything for the front sight as I have an A2 adjustment on my front sight. I'm sure it's a great tool if it's what you want, but I didn't get what I was expecting.

Works good for M4 carbine!!

The tool serves its purpose. The five posts could be longer; it's a little hard to "seat" on the sight dial because they are short.

works fine and I recommend it to anyone with an ar 15 project buy one or two as a gift

Was exactly as described, I use an a1 rear sight with an a2 front sight post. Perfect tool for that combo.
