Soft Rifle Cases
I am in the middle of testing the Kolpin "Space Case". The Space Case is a combination soft rifle bag, drag bag and shooting mat. It also comes with a removable accessory bag.
This bag is 47" long so it probably wouldn't carry a really huge rifle but anything more or less standard sized should fit in it. I can get a scoped M14 with bipod in this bag and this is a fairly bulky rifle in this configuration.
I have only had this bag for a little while but it seems very well constructed and it really makes a heavy rifle easy to carry for any distance.
Once I have finished my evaluation I'll post a more thorough message here.
