I am selling my rifle bag; it fits 2 ARs with a maximum length of 75cm each.
It has a padded exterior, so your replicas certainly won't get damaged.
I had built it with my replica on one side and velcro pouches with magazines and everything I needed on the other.
When I finished it, I bought another bag at the bazaar, so this one was left lying around. So it is new and has never been used.
Feel free to send a message if you have any questions!
