AR mag length

[Jedi]

DO AR mags like bolt gun mags offer a longer OAL in x brand?
if so which one allows longest OAL?

 

[10ring1]

ACS mag in AR10 option is an excellent cheaper alternative to a Large. ACS mags are metal and offer a much longer coal than Magpul and most OEM mags

 

[Bull81]

As stated above ACS are very affordable and can handle a longer coal. The small frame AR15 Mags can handle a little over 2.300
