Andrew (
M0ist0ne), I'm interested in purchasing your
Huben GK1 Rear Sight Mount - v2 Holosun 407k/507k X2 pattern for my GK1 V1 with a Holosun HS507K X2, but not sure if it will fit. On your site you mention:
" .... this is on newer GK1 blocks - PLEASE SEE PICTURE to verify before purchasing! If your GK1 does not have the front feature that is circled in RED ...."
For the life of me, I cannot see what is 'circled in RED' in any picture
. I also cannot find the 1.5mm plug on my GK1 you mention.
Here is a pic of my GK1. Thanks. Bernie
