Some of you may have read that I got a Remmy 870 express and ordered a 18 1/2" Remington factory rifle/night sites for it. Get my shottie Friday but the barrel arrived over the weekend while I was at work. I am impressed, I really like it. I threw it on my Wingmaster to check it out. The sites are of nice quality and glow very well. Standard green dot tritium with the front dot being larger than the two in the rear. The barrel has a modified choke and is parkerized.
