Try to AIWB one, Mr. smart R-H/B engineer guy.
Really?
You're going to challenge me to AIWB carry an AR?
Oh, it is SO on!
Caveat: It'll have to be an SBR. I only have a 26 inch inseam (with long pants) with my chubby little toddler legs. A 16" barrel would stick out of the leg of my shorts and then I'd have to answer some questions.
