Got me a tx22 competition slide for my tx22. Question on mounting a mrd. Got vortex venom and a Burris ffiii. The manual for slide says use loctite 262 and torque to 5.3 inch lbs. Seems light to me and not sure about using the red. I most generally use blue. Any thoughts. Haven't thought about which optic as both are 3 moa dots. Might order another one with larger dot.
