I'm looking in putting some type of optics on my son's youth 870 and just had it drilled and tapped. If I go the ff3 route could someone please direct me in what all I need and possibly where to purchase. Im also pondering on putting a new nikon turkey pro (old style) on it. With the gun being a youth model would there be eye relief issues? Leaning more towards the ff3 and keeping the nikon squirreled away. Any problems in seeing the dot in bright sun light? I had a holosight that when it was bright out I couldn't see the dot at all. I dont know much about the ff3 and it seems like alot of guys like them on here. Just curious. Thanks for any help....
