Snap on Nerf Holographic Sight

I saw some different Nerf sights on here, but wanted something a little different. As of right now, the sight will fit on most Nerf guns with a rail system. It is made to clip right on and be held in place by the small spike underneath the sight. It is still a work in progress, so it is not the most appealing, but I wanted to get it out there and get some feedback or suggestions on changes and improvements. Thanks!
