Holosun 407K/507K/EPS Carry Replacement Screw Set

Didn't work out but FG sent replacement screws quickly for free with a lovely note.

After installing the Holosun 507K, I went shooting with my Cheetah 80 X and within a few magazines, the optic was totally loose. The plate I purchased from you was perfectly tight on the gun. I thought I followed all the instructions I could find. The kicker was that shooting suppressed - which was why I bought the gun - clouded the optic significantly within the first magazine. I'm doing 5 stars for how supportive you folks have been for the few times we've done business. I'll try to use the optic with a picatinny adapter on my Ruger Mk 4 Tactical. Maybe OK because so little recoil but who thought it was a good idea for 2 mounting holes on the same end of the 507K? If it comes loose again, I'll sell it with your nice adapter and screws. I've never had loosening trouble with a rail mounted optic. Thanks again.

Screws were correct size however they were not the exact contour form as the original. Those stripped out at our near 15"lbs on second mount. I believe that's why the originals failed (second use). I feel the original contour fits the optic holes more precisely, enhancing mount snugness to avoid potential drift.

The screws worked perfectly! Fixed my problem with loose Holosun.
