I wanted to send out kudos to the Aaron and Beltfeds.com as well as the excellent folks at BMG parts.
I bought a new M60 mount from Beltfeds and needed a base. Aaron referred me to BMG parts where I bought the base in the picture along with the trailer hitch mount.
This will be great for rainy days at the range where I can sit in the back of my truck up and be covered by my topper while I ping away.
Both companies are outstanding with excellent products. Everything was brand new, well wrapped and I couldn't be happier.
