I purchased a 3.2-17x44 T-PAL scope used in the for sale section here on the Hide about 2 years ago. It has the PCMOA reticle EREK knob #1windage knob low profile quick adjust .25 IPHY adjustment. I was very happy with and seemed to be a really good scope. About a month and a 1/2 ago I noticed it not tracking properly. So I performed a box test with it and it failed. I emailed Telena at US OPTICS and explained my problem. I was given an RMA number to place in the scope to ship in for repairs. Well I had gotten really busy at work and had not got the scope shipped off yet. I got a phone call from Telena to inform me that they had not received the scope and was checking to see if everything was OK and it had not got lost in the mail. So I promptly mailed it to them. A week later I received a call from Jason explaining to me that the scope did have a tracking problem. He explained the year the scope was built (2009) they did have this problem and they redesigned parts to solve it. Then he told me it would cost more to repair it than the price of a new one. So they are replacing it with a new one and let me change to mills and a gap lit reticle. It will take a week for them to get it out the door. Two thumbs up from me to US OPTICS, great job.
