This brass cover plate fills the void in the slide when not using a Trijicon RMR on your Brownell's slide. Compatible ONLY with Brownell's RMR cut slides.
This plate will be high polished brass.
NEW STYLE vs OLD STYLE:
NEW STYLE Brownells slides feature a deep top edge chamfer. The top edge on these slides is different than the front and rear slide edge geometry. To our knowledge, all RMR cut slides shipped from Brownells starting in NOVEMBER 2017 going forward will be the NEW STYLE.
OLD STYLE Brownells slides feature a top edge chamfer that is identical to the front and rear slide edge geometry, this gives the slide a "blocky" appearance. If you purchased your Brownells slide prior to NOVEMBER 2017, there is a chance you have the OLD STYLE slide, but it is possible you received a NEW STYLE.
HOW TO KNOW FOR SURE: Please compare the TOP EDGE of YOUR SLIDE to the pictures of this product to determine which style RMR Cover Plate you will need. Please note that the pictures on Brownell's website may not be updated to reflect your specific slide geometry!
