LAR15 ten rounders, IMHO. They're probably not the length you're looking for though.
Magpul Pmags are still my go too.[/URL]
Since 5 rounds mags are useless and nothing more that fancy paperweights they dont make my list.
Best Mag so far have been the ARTS Pistol mags Gen 1 of course, 2nd place are the IMI Beowulf mags for that extra capacity.
Those mags have never had issues in my Tavor , X95 , APC and ACR
LAR pistol mags are a PITA and some are real jamb-o-matics and the PVC-50 mags are absolute junk.
And if you got lots of money burning a hole in your pocket you could alway get real Alexander Arm Metal Beowulf mags![]()
