Please see pics. I bought both of these 30+ years ago when my son was learning to shoot.
The globe sight is excellent and includes the inserts pictured. It was specifically made to fit on the M-1 male sight dovetail on the GI gas cylinder assy. It is retained by a vertical set screw. You can easily install and remove it without any alteration to the rifle.
$50 plus 5$ shipping.
The compensator is a US made early style circa 1980. It simply replaces the gas cylinder lock. Like the sight, it can easily be installed/ removed without any alteration to the rifle. This comp only vents upward, reduces muzzle rise and recoil, but doesn't vent muzzle blast to the side. Something other shooters appreciate.
$45 plus $5 shippingg.
The pair for $90 and $8 shipping.
