Has anyone here had any experience with the Vortex Strikefire? I was given a 50 dollars gift card from Cabelas,& a 100 rubel bonus from the boss so I picked one these up for my M4. So far without going to the range I am impressed with the features, quality, and price. Any input would be appreciated, but I guess it is a little late, cause the greenbacks have been spent already. Maybe I'll give Ya'll a review:)
