    Kick ass plate

    Posted by Raymond on 14th May 2022

    Decided to pull the trigger on the 509T. As a preemptive measure I thought I should buy a plate for the Glock 17 MOS, the plates it came with would not co-witness your sights. The Battel Steel HE509T plate does. Solid plate at a super reasonable price. 10/10 would recommend, fits snug and securely. 509T sits flush on the plate.

    509t baseplate

    Posted by CLIFTON KIMBALL on 11th Apr 2022

    Just what was needed, running a 509t on a glock40mos. This plate is .167 lower then the mos plate + 509t plate (mounts to rmr pattern). It is much lower and looks way better. Being only one plate vs the factory 2 together I think is going to hold zero better.

    Optic mount

    Excellent quality, steel allows the mount to be thinner to keep the red dot low. Excellent fit for my 509T.

    The order process was simply and easy to purchase. The product was delivered in a timely manner. It just didn't fit the G19 and the cut on the slide. I'll have to return it. Nothing Botach did wrong.

    Great product with an excellent fit. Would have liked to see lock tight preapplied to screws but other than that, perfect.

    Botach 509T plate Glock MOS

    Posted by Drty Bubbz on 3rd May 2021

    30-40$ cheaper than CHPWS. In my opinion the best if not better. Now if we can only get a plate for the trijicon rmr/sro glock mos. over all great product.
