We have several Leupold mark 4 4.5-14 illuminated tmr reticle scopes. The complaint is that at times the reticle appears as if its two small lines running parallel instead of a thick black line. Others have described it as being blurry. The problem appears to be intermittent. I sent one scope back to Leupold for repair. They stated nothing was found broken, however the person using that scope stated it was good for about 4 months then went back to having the same problem.
