Holosun 509T X2

I used 15 and it came loose. So it’s now at somewhere between 20 and 25.

NOTE: 15# for the MOS plate screws. 20# for the clamp bolt.

I'm mounting my 509t tomorrow, using the holosun steel mos plate. What torque should I use on the screws to mount the plate to the slide?

Wait. I was tired when I posted earlier. I thought you were asking about the clamp.

Plate screws at 15, with threadlocker.

Ok! Haven't don't it yet

I agree… with the steel plate I’d use 15in/lbs for plate-slide and 20in/lbs for the optic-plate clamp screw.

Thanks gents. Mounted up very nicely. Really impressed by the steel 509t plate from holosun.

Anyone still using these? Any thoughts vs the EPS?

Great optic. I can't conceal it personally. So it is either going on a carbine as an offset or being sold.

That is revealing. If I owned an aluminum plate, I'd be planning on replacing it.

Photos I have seen up on a private FB group in the past 24 hours strongly support that plan. (And perhaps a helmet, with ballistic visor, if you’re using any cross bolt pistol optic on an aluminum plate.)

Where was the failure point? I'm guessing the optic worked itself loose after the soft metal of the plate deformed under recoil.
