I have both the AG Precision Rifle Case (52") and the M2010 case and they're both very high quality bags, as you'd expect from anything AG. I've never tried putting them in my Pelican 1750 but they're both the same length so shouldn't be an issue.
I also have one of those Voodoo drag bags I got years ago and it started falling apart pretty quickly despite relative light use.
I have a Armageddon gear precision rifle case and it is a really nice case none of the BS you don't need, have never put it in a hard case but would probably work, just a real nice soft rifle case.
The Armageddon Precision Rifle case was delivered today. Fits perfectly in a Plano AW2. You have to place it in the case upside down so the muzzle end fits between the recessed wheels. The Plano is an 1” or 1.5” longer than the 1750. You would have to stuff it in there to make it work in the 1750 IMO.
Glad I didn’t order a 1750. I’m going to order a Nanuk 995 instead as it’s a bit longer similar to the Plano.
Optics Planet has the Nanuk 995 in Tan on sale for $199 which is a killer deal FWIW.
Rifle in the pic has 26” barrel. IMO this case is made better than the higher dollar Chinese bags. You know the brands I’m talking about. What you would expect from Armageddon Gear. The foam in it has to be almost an inch thick. I wouldn’t hesitate to fly with it.
Just confirmed, with a 52" armageddon rifle case, I can fold my AXMC and put it into it. Still enough space to put a few things in the front pocket as well.
