I bought my 6" 617-6 slightly used. It had a very attractive gold dot front sight on it, and it shot 6 or 8 inches low. I measured the sight and as nice as it looked it wouldn't work. I swapped out with a factory height sight and it was just fine. I have since added a Burris Fastfire red dot, and love it. It will shoot right at 1/2" at 13 yards (from a rest) with bulk Remington plated bullets, and better with Aguila Standard Vel.
