Holosun 407C/507C X2 and X3 Replacement Screw Set

These are great! My stock Holosun screws kept backing out with +P ammo. These were just a little longer but completely fixed the problem. THANK YOU!!

The screws themselves seem well made as well as the locktite applied however with the stock adapter plate and a Holosun 407C on my FN 510 Tactical, it did not fit properly. The longer of the 2 screws did not seat past the second thread barely holding on the optic despite appearing it was on tight. Keep in mind if your optic requires an adapter plate, these screws are not long enough.

I've written dozens of articles on RDS and how to mount them. A key point is never re-torque screws as they can snap off -- always replace them.

And where do you source quality screws? Certainly not from dodgy sellers on that South American forest website.

Helpful hint: Label the bags when your order shows up.

I ordered two sets and package was tore open and missing two off the 8 screws that were on my order. After Freedom Gorilla was notified. My complete order was replaced quickly and without question. Stand up guys definitely will do business again. Thanks again

Back ups are a thing. change and or replace screws if needed

Excellent service, Tyler helped me find these screws and they fit perfectly, he even texted me an answer after hours which is unheard of anymore. I will continue to buy from them because they've shown me that every customer matters. I recommend this company to everyone.

Didn’t fit my plate

great product and a vendor that supplies excellent documentation

The screws might be good but non of them fit in the Sig SAUER slide. The slide is from a Flux Rider P320 which a full size P320.
The screws from the cover plate can not be used where the holes of the Holosun match with the holes of the slide which are not the same holes for the cover plate

Exactly as described, fast delivery.

Great customer service and fast shipping would reccommend

Easy to find and order. There was a little mishap but emailed CS and they took care of it the next day. 10/10 will def be ordering again from here.

The screws are of good quality and the customer service is the best. They are always willing to help get you the correct item.

Exactly what I needed to mount my holosun 507C to a Springfield Echelon 4.5F

Just what I needed 👍

Juat what I needed … good quality & well priced product. Packaging is very good and delivery was prompt. Highly recommend vendor. Will buy again as need arises.

Exactly what you need for multiple weapons/optics.

Since the screws that came with the optic did not work these were a massive help

This is pretty much the best way to get replacement screws

Perfect length to mount my green dot Holosun 507c to the Cz P10 C.

I don't know because I have not received it yet. Becoming quite irritated.

I tried contacting Holosun by email. The link did not work. I'm extremely happy to find your company with the screws I need. Thank you very much!

Perfect fit, thank you

Looks great, very reliables

The screws were a perfect fit. They were delivered within a few days.
