I have been searching for a heavy duty enough backpack that can store my take down rifle (AI PSR) that can accommodate my 300 WM barrel (24"). Also, it has to be well padded so that it doesn't imprint the rifle. So far I really like the Nemesis backpack, but I don't think it will fit barrels longer than 20". I want a backpack that doesn't stand out as "tactical". Any thought? thank you in advance.
