Thanks for the input.

The Bugbuster looks like one of the few options in the under $100 price range. I would need to check to make sure there are no mounting position issues due to the compact tube length.

The SWFA would be great but I'd like to keep the price a bit lower on this one. For over $100 I'd probably get another Primary Arms 4-14 FFP like I have mounted on a PCP. It works very well for hunting but it's dang heavy.
