Looking for a solution to mount your favorite compact Holosun optic to your MOS Glock 17,19,20,21,22,23,26,34,35, 45,47,49? The GS K-Plate is the answer!

The K-Plate optic adapter plate, milled from 416 stainless steel in Nashville, TN, fits perfectly into the MOS footprint of your Gen 4/5 MOS Glock 17, 19, 34 etc. This allows you to install the new, compact Red Dot optics that have the K-footprint. Make sure to watch the video.

Any optic that has the 507K footprint will fit and function on the GS K-Plate. Here's a list of compatible optics at this time:

Holosun 507K
Holosun SCS Carry
Holosun EPS
Holosun EPS Carry
Vortex Defender CCW
SHIELD RMSc and other RMS variants
Viridian RFX15

The K-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 but does not interfere with function whatsoever!

The new GS K Plate - Designed to be the perfect interface for the smaller Holosun optics to the MOS mounting system with the thinnest plate possible. Sits your optic nice and low and tight so it looks like it grew there!

Please note: The K-Plate supersedes the factory MOS plates. Factory MOS plates are NOT required for use with the K-Plate. The plate comes with 2 optic mounting screws, 2 plate mounting screws (M3x.5 x 6MM) and a 1.5mm allen wrench.

This same MOS adapter plate mounting concept is available for the Trijicon RMR and Holosun 507C and like optics with the C-Plate. #1276

This same concept is also available for ACRO footprint optics such as the ACRO P-2 and the Steiner MPS, here. The GS A Plate - #1279

Very Well Made, Minus Screws

by

Love the plate. Made mounting my Holosun EPS to my G19.5 a breeze. I would not recommned using the screws for the red dot that come with this though. They use an allen key that is too small to use for the 15 in-lb the instructions from Holosun call for. I'd recommend to stick with the Torx screws that come with the MOS plate. I was forced to do that when I took my optic off to change out back up irons.

Well made besides that. Machining and coating are great.

G47 MOS K-plate SCS Carry combo, love it!

by

Great replacement plate for SCS Carry. Put several hundred rounds thru my G47 and it has performed perfectly. Absolutely great fit for the Holosun SCS Carry, no wobble and fits like a glove like Lenny said. Great quality product from GS. If I get another Glock mos, I will be using this same combination.

High quality and a perfect install (with the proper tools)

by

If you've purchased this plate for the Osight SE and Glock MOS standard slide (1"), this adapter is absolutely perfect. I've been installing red dots for a few years and this plate and mounting screws are remarkably, high quality. As with any install, use the right equipment and you'll have no problems at all...high-quality hex bit / extension (to clear the sight body) and torque driver (FIX-IT-STICKS torque extension is great) to get the best results. This plate is worth every penny and hassle free.

The Best Ever

by

This plate is Absolutely Amazing. Nice snug fit. Used the Osight SE on G19X mos. Highly recommended

Great Plate, Bad Screws

by

The plate is very think and sits low enough to co-witness an EPS Carry with standard sights. However the screws that come with the plate are terrible. First, the optic screws are long enough to mount optics. Secondly, the screws used to mount the plate itself are cheap. They strip after the first use.
