HE509-RS-ACSS
Written on Jun 14, 2023
This optic is enclosed so dirt and rain are kept from interfering with the reticle. To mount this optic on a Glock gen 5 9mm (17, 19, 45, 47) you will need to order a MOS adapter plate that is specifically designed for the ACSS model. The adapter plate for the 409T model will not work and it says this under the description of this optic (if you read the whole thing - I didn’t). I found the ACSS MOS adapter plate at primaryarms.com.
The Glock MOS 02 adapter plate is compatible, but it puts the optic too high and you would have to cut your screws down. There isn’t enough thickness in the 02 plate to secure the optic in my opinion. So the ACSS adapter plate is the best option.
