I used to clamp two mags together for my HD carbine, granted this is an M4. My thinking behind this was so I could load 20 rounds into each 30 rounder and leave them loaded for a very extendec period of time without damaging feed lips ect, plus this would give me 13 extra rounds over my typical mag loadout of a singe 27 round mag.
I discontinued this because the mag not in the mag well covered my bolt catch and when I switched mags the empty would cover my ejection port. Plus it adds more weight and bulk to a rifle i need to be as light and as bast handling as possible.
The only time I would consider doing this again is for a stationary defensive carbine. I would never utilize a clamp for a patrol rifle especially with aluminum USGI mags. Too much chance of tweaking the mags and causing a malfunction.
I was pondering the same thing, I set up my mini as a bug out survival type rifle. Pseudo scout with the hilux 2x7 scope ultimak rail and leopold qd rings. The Spector sling and mag holder lets me carry a extra 20 rounds, a clap would total it to 60. The problem is I only have 20rd mags. About 14 of them but with the current bs scare I'm not buying any high caps now.
I would like to know whats the best clamp is for 20rd mags and how people use them. Any information this subject would be greatly appreciated!
Just seems to me clamping mags would just slow down a mag change and throw off the balance a nd handling of the rifle. The more crap you hang the more cumbersome the platform becomes. I use mag pouches on a belt and a chest rig, carries my mini mags and pistol mags.YMMV. just seems more show than go.
