Ade Advanced OpticsPicatinny Mounting Plate/Adapter/Mount - Compatible with Holosun 407k/507k/Holosun EPS Carry, Shield RMSc, Sig Saure Romeo Zero, Crimson Trace CTS-1550, ADE Spike red dot Sights

No complaints at all! Came with everything I needed.

Great adapter for RMR footprint for RDS.

This doesn't fit the romeozero without modification. I had to remove/ file the front 2 lugs. I was able to pull one out but the other had to be grinded. I suggest the company doesn't pressure fit the lugs at the factory but instead leave them out and have the customer install if the optic needs it.Once remove worked great.

Mount is well built. Fits Crimson Trace CTS-1550 perfectySeller is a pleasure to work with and thier customer service is A+.Thank you!

UPDATE - If the one you receive looks like the one pictured (with four chrome posts) it will fit! The one I received from Amazon did not have four posts... only two. I ordered from another vendor, and it matches the picture, and it works on my Swampfox Sentinel, and I am assuming the others.I ordered this for the Swampfox Sentinel. The Sentinel does not fit this mount. Was the wrong item pulled incorrectly at Amazon? I do not know, as the label on the product does not indicate which red dot models it fits. The barcode label says X002ZGZXN7. I hope this helps.

I mounted my cts-1550 red dot on my Ruger pc charger and it worked perfectly.

You really want to contact points for Picatinny rail this one once I zeroed it if I would torque the whole mount left or right the poi would move left or right in the pins were in the right place. I had to file them down total waste of money.

Excellent quality mount. I put a Sig Romeo Zero on my Ruger PC9 rifle pic rail. Sig RZ fits on this mount perfectly! Fast shipping as well.
