450 bushmaster - Thompson Center TC Multi-X 3-9X40 Rifle Scope

The scope looked great out of box. Nice camo coating. Mounted, the reticle was clear as well as the glass. I put it on a ruger american ranch 450 bushmaster. After about 15 rounds the reticle was dim and blurry. The glass was very blurry. The magnification knob would not move off of 9 but was stuck at 3x magnification. I got the knob to move but it is stuck on 3x no matter what setting. I can only get the glass and reticle to be clear between 5-6 but still stuck at 3x. I think this would be a decent scope on a lower recoil rifle, especially for the price. I would not recommend use on a high recoil deer rifle
