I bought an Allen 46" bag through Ebay ....$26.95. My Saiga .308 w/scope fits well, and the SGM mags
fit in the pockets. I also bought a 42" for my Saiga 12
Their Ebay store is: Wholesale Hunter. They have bags in 32", 37", 42", 46".
I go to the range once or twice a week, and the bags are wearing well. I have no complaints with them.
