Great option for mini-30 modification - Aimtech Second Sight See Through Solid Rifle Mount for Ruger Mini-30 Scout Rail

You might see similar items if you are shopping for mini-30 parts but this mount offers a nice tunnel to see-through that still make iron sights viable if your optics fail you in a time of need. Only didn't give it 5 stars because I had to sand down part of the clamping system finish so the rail system could attach on to it, not noticeable from the outside when completed but this is suppose to be a no gunsmith no fuss type of item to attach.
