Just put what look like medium size 2 piece mounts on my 99s,dont know make of mounts there double alan key that clamp onto the gun and 4 alan key screws that clamp scope.the front on the scope is touching the gun,now then when i try n scope in its way to low the up/down turret is turned all way up and its still 2-3 inches to low,ive tried winding all way down to low then turning up to all way up but nope still to lo.any ideas please ?? Im sure its mount issue but id thought id ask here first.cheers lads
