** These will NOT work to attach the 507K to the Sig Sauer X Macro. For the 507K you need the 8mm screws **
This is a set of three screws for mounting many of the most popular Holosun Red Dot Sights to your pistol. We include three so when you lose one on the floor you still have enough to mount your sight... (we've all been there and done that).
These ones are 6mm long M3 - 0.5 Check which length you need, or buy the "Holosun Bag of screws" we offer to cover all possibilities...
These screws use a #10 Torx bit (available separately) for install.
