Picked up a new one from ebay, new and way less than any store. Went to the range (nice big targets) to sight it in. What a sweet idea, I started with 10 yards to get some idea on the set up. Set up is super easy. I didn't slap the tape on and hope for the best, I took a field point and put a little scratch on the side. Went to 20 and did the same, up to 40 and then it was to day to play. Now all I have to do is select the right tape, or just use the blank piece. Looks like one of the pre printed tapes will be spot on. It seems to be easier to shoot with one pin vs. the 5 pin tru glo. After one shot with the tru glo the bubble was 4 or 5 bubbles, not this new one. Best thing I've done to this Bullet X. Next to the EXTREME Strings.
