Regarding the discomfort of the swivels used to attached the strap to the fore-end: Some old-school Laser Products/Surefire shotgun fore-end Weaponlights, such as the one on my wife's 870, attached the strap with small bolts. (Her "Baby" has an 18" barrel.) I see no reason this cannot be user-replicated with Magpul fore-ends, by drilling holes in the ample real estate available. I might dispense with the bolts, and use paracord lacing.
