Here's a picture of a few of those, one threaded through PALS with a field repair female kydex buckle, one just laying there so you can see that the webbing is sewn to 2 of the 3 bars of the 3-bar slider, which keeps them from coming unattached like Kifaru's applications with their 500D organizers and spotting scope pockets.
Firecog nailed it...
There's another pic of a few shell/game bags we're going to be using this weekend pheasant/grouse hunting. One's an XTL lid with a spotting scope pocket rolled up as a dump pouch for birds, (shells in the main pocket of the lid) the other's a 2qt pouch with Rugged Stitching predecessor to Mel's PocketUp Morph Pocket, another dump pouch really, inspired by the Loco (then G1 22mag, then Mel's Morph and Terrier Patrol Pack). Lots of in and out of vehicles, I got sick of screwing with vests trying to get birds in/out. Dump pouch for birds on a sling able to carry a box (or 2 or 3) of shells.
