I purchased a HS507K-X2 ACSS from Freedom Gorilla and it fit perfectly on my pistol slide without a plate, thanks to your online fitment guide.
Couldn't have been happier until range day and I lost my screw for the battery tray.
I call Freedom Gorilla and they sent me 4 screws that afternoon.
I've been shooting and loving my optic
You guys are awesome 👍
Thanks
P.S. tighten the battery tray screw when you install your red dot !

The optics are as advertised, Ive run Trijicon RMR's for years my Bride has never had a handgun with an optic the Sig P365 is her first and she loves it as do I. When we bought the pistols I was looking for information on what optics would be a direct bolt on, the Freedom Gorilla you tube video answered all our questions, the service was fantastic and we will be buying from them again very soon!!

I was looking for an optic and a mounting plate when I came across Freedom Gorilla. They were extremely helpful and had everything I needed. Quick ship & delivery.

Love this 507k ACSS VULCAN RED DOT. Invest in the extra money for this. You won't be disappointed.

Fast Shipping , great price , what more could you want. I will buy more from FreedomGorilla.
