About a year ago I bought a Midway USA "big range bag".
It was on a "special" "special" sale. For $40. I think the "ordinary" price was $100.
It is quite a bit bigger than I see many other shooters using at the range. About 24" by 18".
It has plenty of very usable exterior pockets. Both on the sides and ends.
Two removeable rectangular gun "rugs" for the inside.
Plus a internal rectangular "bag" with handles that can be lifted out.
Sorry, don't know what I did with the receipt. So, part no. = ???
But, I'm sure you could find it on their website. Good luck !
