Seems great but... - Shield Sights SMSc Compact Shield 1x Mini Reflex Red Dot Sight

Very nice product came with a cover which I also wasn't expected so bonus. purchased for a hellcat osp. The directions are terrible for assembly to firearms. They are just awful. Went to YouTube which had very few directions of how people actually put them on. Normally people post that but I'm assuming it's because they had as much trouble as I did deciphering the useless and nonsense. It did not sit well onto the gun but I had read another person used gun oil on the post where the site sets. I had to lightly snug the screws down then forcefully wiggle the sight until it snapped into place. This is not an optics planet failure but it is a failure of the manufacturer for sure.
