Probably the wait time. C-Sharps can generally make you a rifle within a couple months. Last I heard which was sometime ago Shiloh was a 3 year wait. They have a loyal following but so does C-sharps. I have 2 C-Sharps rifles and my experience with them was nothing but positive. In fact I broke a firing pin on my Hiwall the day before deer season and they got it to me at deer camp on Monday which was the next mail delivery day. I did manage to jury rig a firing pin out of a drill bit and it killed a very nice buck opening day.
