what up gun wizards and gurus.... just completed my EBR chassis swap. fixed the mag by removing the mag release, then drilled and tapped a 6-32 hole for a hex head set screw which I silver solder'd in place.
I don't love how the receiver design of the M1A relies on the trigger housing clamping it down. I was thinking about drilling / tapping a 10-32 hole and adding a set screw w nut which clamps against the sling swivel attachment on the ebr chassis...... pic attached.
would not apply any torque, just snug the hex bolt finger tight against the sling attachment then snug the nut down finger tight on the other side
thinking that would hold the rear of the receiver firmly w/ zero movement in the horizontal plane as well as lock it down in the vertical plane for zero movement.
would this addition improve "repeatability" by adding another component keeping the receiver locked down??
