I recently started building a new "active shooter" rig for my patrol gear. In my haste I must've had .308 on the brain, and I ordered large mag pouches instead of the necessary AR15 size
now that I have them, I really like the idea of having a .308 rig... although it'll never likely be used on duty.
So here's my options... (I need two pouches)
1. Spend the money and just buy the correct AR15 pouches. $28 ea.
2. Use kydex inserts ($7-$15 ea) to hold the smaller mags inside the larger pouch. Esstac and Haley Strategic. Maybe even fix a short bungee style pouch inside?
3. Half tempted to sacrifice a LR-10 mag body and use it as an insert. Remove the guts, grind the inside smooth and maybe split the spine. An AR15 mag "almost" fits inside the LR PMAG, and I'd only be out of pocket $15-$18.... just have to get over the idea of destroying a perfectly good magazine.
