I've heard of Ingram barrels before, but not often. As to the scope...I love the Pro Class from Tasco. I have four of the 4X and the same 3X that you have. I really like the 30mm tube. I've never had a problem with them holding up to recoil and one is mounted on a Super 14 .44 Magnum. Mount the optics straight and solid and it will hold.
