Left side view
Left view showing detail of the original AR TEL mount, one problem that did arise w/this system was the "single point" mounting, the lg thumbscrew was the single mount point, backed up by the horizontal & vertical grooves on the rear of the mount fitting into dovetails cut into the receiver. Losseness/movement of the screw/mount could result in wear to the goove/dovetail joints which caused zero problems, this was later addressed in the M21/M25 rifles by changing to a 2 point mount for more rigidity.
