Over what time period?
If you're keeping your magazines unloaded and you're waiting for Armageddon sometine in the far future, then, yeah, the PMag may be a viable choice. If you keep your magazines loaded (with the spring and magazine body under tension) then my experience over 30+ years is that plastic body magazines are NOT the way to go and will feed less reliably than steel or aluminum magazines.
Hence............... The Lancer L5 AWM. Plastic body.....steel reinforced lips. Never say never. Never say always. Lancer Systems L5 AWM Advanced Warfighter Mag AR-15 223 Remington
