I had to send it back and it never has worked - Hi-Lux Optics M40 USMC 3-9x40mm Rifle Scope, 1in Tube

the reticle rotates in the tube if you adjust the magnification ring faster than a battleship turret and at only 16in lbs of torque (standard mounting pressure for most rifle scopes) the tube became deformed. I bought this for an m1a Vietnam reproduction I was building and I was highly dissatisfied with this optic. ill most likely end up using it as a piece for a fake rifle im turning into a lamp. I bought it after trying to find reviews on it myself and failing to find any. I now see why there aren't any
