Fair enough. I guess having lugged an M4 over and through some miserable-assed terrain every day without ever once accidentally dropping a mag I didn't consider that point. Nor did a 30rd mag ever cause me undue problems carrying it.
I certainly respect the purity of the BDL, and DBM isn't necessarily worth it to everyone. As much as anything I enjoy immediate control over my ammo supply, whether it's to load or unload. Fumbling around with loose rounds in the dark with cold wet frozen hands sucks.
I mean my comments with all respect. What works for one of us isn't the solution for everyone. I've never liked the BDL setup, my very first deer rifle 30+yrs ago was a 788 with DBM. sticking with BDL is cheap, and you can always switch it over at some point if you feel the need.
