Something to think about when buying a rifle case
One thing people tend to forget about when they are packing up all of their guns and gear for a shooting match is how heavy everything gets when you load up all of the pockets. I’d say that about 90% of assault rifle cases I own have stowed and empty rifle magazines and people forget there is a difference between 5 empty Pmags in a gun case and a rifle case with 150 rds of 5.56 ammo. Especially if you have using 75gr ammunition. I learned the lesson about ammo weight when I went to a gun show and tried to leave with a thousand rounds of 7.62×39 ammunition and 1000rds of .223. It was impossible for me to carry it and I learned to appreciate the 5.56 ammunition.
When it comes to choosing a rifle case for a battle rifle, I think it’s really a good idea to consider a drag bag. That gun is heavy enough and even the designer of the FAL knew that it would be more comfortable to carry that gun with a carry handle than over your shoulder at times. When it comes to carry 15-20lbs or more, you really gotta carry on your back. Gun cases may come with a strap, but a drag bag is meant to be thrown over both shoulders. I have a really nice rifle/drag bag from Elite Survival Systems and use it for my DMR configured DSarms FAL STG 58.
