As Wolfie has stated, mags and ammo make the AR in many cases, Thermolds and Orlites are popular and for range work they seem to hold up fine. If I were you, I'd be looking for some 30 round Labelle mags with the green followers these may also be stamped D&H or General Stamping, but they are the same company ...There are a few others out there who are getting good reviews including --Universal Industries/Okay Industries/Colt/NHMTG (same company), and Adventureline/Parsons/Center Industries (same company)...WHAT EVER YOU DO, STAY AWAY FROM ANYTHING STAMPED -- USA, Triple K, Western Metal, Victor, Millet, ProMag, RamLine, and Eagle. Every time you get a jam mark the mag, then decide how many marks required to trash the thing, keeping in mind how you'd react if your life was depending on that baby to function properly.
Ammo is another issue, IMHO Lake City XM193 Mil Surp manfactured by Federal is the best you can buy, problem is, with the war this ammo is becoming scarce, I understand that you can still order it from Mirage Tech (Click Link)
, But it is phone orders only. STAY AWAY from the old laquer coated Wolf ammo...If you are shooting Olympic throw it in the creek...With that said, I am really likeing the new Wolf Polymer coated
.223 rounds for plinking, so far it seems to feed reasonably well albeit a lower power round than my favorite (XM193).
Clean that weapon! It is one of the easiest firearms to clean in existence, if grit is causing slow extraction you can see how the following round will feed improperly.
Keep us updated would ya? Good luck with that monster.
