because i live in a building with some snoopy people, i actually made my own
mostly just for fun while locked down.
i can cover a regular case with a beach towel or blanket, but people may even see it in the parking garage or ask in the elevator.
i did look at a few of the commercial offerings (there are several hard and soft) but tbh, they looked like cheap cases with some extra foam and some velcro hold down straps and a $100 price hike.
i might get flamed for this, but since you sincerely asked, here is that i made since i already had a gig bag i wasn't using.
if you do this with a soft case, get a "gig bag" as they will have extra pockets for other gear, and often have backpack straps.
obviously you don't need to do all this, and you can just add some vecro hold downs or wrap a towel around it and throw it in there.
so this was the gig bag i had laying around. pretty sure i paid less that 100 bucks. ibanez powered acoustic gig bag.
i have been cutting my own kaizen foam for cases for years, so i also had sheets of it already. it is pretty cheap online.
it was deep enough for a handgun under the grip (p229 in my case). and taco pouches under the stock.
shape of the case did not accommodate sun shade on the scope, or the bipod (qd is preferable).
okay, ready for shit about the fin grip, but it has a thumb rest, and i don't wrap my thumb around for hunting or target shooting.
you can see the taco pouches hold 3 mags for Scar and Sig.
showing how the rifle lays in the case
fits everything that would fit in a normal range bag with pockets or pouches.
