Hello all. I have a Ruger Mini-14 Range Rifle that is sort of my primary defensive carbine. Its benefits its that its light, handy, and reliable. I'm tempted to put some better optics on it beyond the supplied peep sight. However, a traditional scope is going to be too large and cumbersome for this application. Can anyone recommend a light, small, and reliable alternative? I'm thinking single-power scope or ACOG, but am totally open to suggestions. Thanks much.
