GS COA Adapter Plate for MOS Glocks (Except Slimline) - PREORDER

PLEASE NOTE: These plates are currently in production. Please expect a 4 week lead time for this product to ship.

Designed to adapt the Glock MOS cutout to fit the Aimpoint COA.

The new GS COA Plate is the perfect fit for the Aimpoint COA. The COA Plate sits right into the MOS mounting system with the smallest profile possible. Sits your optic nice, low, and tight so it looks like it grew there!

Please Note: This adapter plate comes with a sight set that contains a proprietary taller front sight to match up with the rear sight elevation. Normal COA compatible sights will not work with this plate.

The COA Plate is precision machined from 6061 T6 aluminum, while the rear dovetail sight adapter is machined from 416 stainless steel right here in Nashville. It is designed to fit perfectly into the MOS footprint of your Gen 4/5 MOS Glock 17, 19, 34 etc.

The COA Plate also functions with Gen5 MOS G22, 23, 20, 21 however since these slides are wider it does not fit as flush as the 9mm options. It's literally 1/16" on either side of the plate that is visible which does not interfere with function whatsoever!

Please note: The COA Plate supersedes the factory MOS plates. Factory MOS plates are NOT required for use with the COA Plate.
The COA adapter plate does not fit Slimline Glocks (43X/48)
