This comes with the screws to mount the plate to your device. It does not come with screws to mount t the optic, use the screws provided with your optic to mount to the adapter plate. *DOES NOT FIT 1911 SLIDES and does not fit some 2011 slides **Fits with the standard mounting screws for the RMR optic pattern – Holes are 6-32 tapped holes (standard for RMR) Simply attach this adapter plate on the existing RMSC optic cut as a regular optic plate. Screws are provided for mounting the plate, with pre-applied loctite. (Provided screws are M4x.7, and 6-40. Test fit your screws, be sure your using the correct screw, some manufactures use uncommon hole threads) Compatible with all RMR Optics: Example Compatible with Trijicon RMR/SRO Holosun407c/507c/508t/509t/EPS and ANY RMR footprint optic Holes on the plate are tapped to fit the standard thread for RMR – which is 6-32 thread type holes. The plate comes with 2 sets of screws, M4x.7 and 6-40. **PLEASE CHECK YOUR FITMENT!!!! ADAPTER IS OFTEN RETURNED BECAUSE OF THE FOLLOWING REASONS: YOUR SLIDE IS NOT RMSC PATERN AND DOES NOT FIT, make sure your slide has a RMSc cut on the top. SLIDE IS Not a true RMSc-spec footprint, or Modified, or From manufacturers whose RMSc cuts vary from industry spec (BUDGET SLIDES) This can cause compatibility misunderstandings even though the product is functioning correctly. MAKE SURE YOU HAVE THE CORRECT FITMENT BEFORE PURCHASE!!! Review: Fits perfectly, unless you have the LCI - The product fits onto the proprietary sight mount perfectly, except the front of the plate hits the loaded chamber indicator and prevents it from rising as a cartridge is loaded. It was an easy fix, and a few minutes with a file made a notch to allow the indicator to rise. The adapter plate works perfectly, just needed a little help with the CA version of the p365. Overall great product, and half the price of other equivalent products. Review: Does not fit CZ Shadow 2 Carry - Was originally purchased for a CZ Shadow 2 Carry but the plate was too shallow for that intended purpose. I used it instead on a Mossberg 590s and it’s a wonderful fit. I used my own screws so I cannot attest like other reviews noted. ## Features - RMSC to RMR Adapter Plate easily converts Any Slide with an RMSC cut to fit an RMR Optic Cut Footprint to fit a RMR Red Dot - comes with the screws to mount the plate to your device.
