    This screw is a perfect fit for the Holosun 507K battery tray. My factory screw flew out at the gun range and could not be found. I ordered 4 of these, and I’m back in business.

    Although it’s not a flat head screw, it fits like a glove. Make sure you have a decent collection of small Allen keys to figure out the size needed. Put that in your optic box or tool kit for range days/work if in the sector.

    Perfect fit for my Holosun battery tray. Spend the extra couple bucks and get the allen key also.

    This part fit perfectly in my Holosun HK570. Since the head of the screw is phillips as opposed to the holosun flat head, the phillips wrench size is .050. Great product and extremely fast shipping speed. Thanks again!

    Fits perfectly and is cost effective. Rarely do I pay close attention to a review but it did this time. Someone said buy four. So I did glad I did I won’t be stuck without again. Fast shipping too!

  6. Corbin Kingsbury (verified owner)

    Just what I needed. I bought 2 so that I could lose another one. Shipped super quick!

    although it took 10 days for this to reach my house, it fit properly and I am happy with it. TACRIG was great. USPS not so much.

    Very food fit

    Fits perfectly on my Holosun 407K. Kind of sucks that it didn’t come with the tiny hex wrench but no big deal they are cheap even when you get a bundle of them with different sizes always could use them. I would definitely suggest putting a little dab of blue lock-tight on the screw so it don’t go flying off while shooting. That’s how I lost the original screw in the first place. Never could find that little thing luckly I find this site with the correct screw. It did take a while to get it but not too long. It was maybe a little over a week to be delivered nut not complaining. I would definitely recommend Tacrig for replacement screws for your optics. Only reason I didn’t give a 5 star is because it didn’t come with the tool but other then that I really appreciate Tacrig.

    Better than OEM, Allen head a big plus.
