    I think they're L5s. Hmm, well, uh, if they're crap . . . I need practice with failure drills anyway.

    I must have gotten a bad batch of the Thermold 20's. Of the six I bought, none were reliable. Three of them had feed lips so weak they couldn't hold more than 15 to 18 rounds without the rounds popping out of the magazine.

    The original Thermold company made some good magazines (IMHO). I'm not so sure about the new company that bought the name and molds.

    Besides my bad experience with their 20 round AR magazines, I had feeding issues with two of their HK91 magazines (the only ones I ever tried).

    OTOH, their AK magazines seem to work well.

    YMMV.

    My 6920 had it's first malfunction today (1,600 rounds so far). It was a failure to feed of the 2nd to last round of Federal M193 in a March 2009 production 20 round PMAG.

    I haven't used that magazine very much, mostly because of threads like this.

    Coincidence? I don't know, but I don't see myself using that magazine again any time soon.

    For 300 Black I use Brownell's 20 round magazines.

    I cannot recommend the Lancer 20 round AWM.

    I cannot recommend the Lancer 20 round AWM.

    I love 20 round mags for their compactness. I love Glocks with plastic frames. I LOVE the idea of translucent mag bodies to monitor rounds left. The Lancer AWM is a plastic, translucent 20 rounder. What’s not to like? I ordered two of them from Brownells to try out.

    Because of a bad experience with a couple of similarly designed Ramline 30 round translucent mags, where the mags would water fountain 2 or 3 or more rounds, out of the top of the mag when slapping into the magwell. I was a bit cautious but hopeful 25 or so years have improved translucent AR mag design.

    I fully loaded both mags to 20. I “settled the rounds in the mag” in the usual way and sure enough, 1 or 2 rounds would water fountain out of the top of both mags. The AWM’s have wrap around metal feed lips, so I didn’t think that would happen. I “slapped” the mags into several Colt AR’s with bolt carrier locked back, figuring the mag well would “reinforce” the wrap around feed lips to reduce the water fountain effect. Nope….one or two rounds would pop out into the open AR action. I repeated the test numerous times with the same result. YMMV.

    I suppose 1 or 2 pop outs per slap are better than 2 or 3 pop outs a generation ago. I suppose they would be great mags if they were loaded gently and NEVER slapped into an bolt-locked-back AR. Without shooting them, I returned the mags to Brownells with a comment on the return receipt. I don’t need to see if they are shooting reliable as I already have reliable USGI mags. I REALLY wanted the translucence feature. I repeated the same test with 20-round and 30-round USGI mags with the same slapping force, if not WAAAY harder, and no rounds popped out.

    Furthermore, the 20 round AWM’s are significantly longer than 20 round straight mags. Nevermind the significantly thicker baseplate area verses straight mags. I took photos of this size difference as a reminder.

    I believe the dimensional restrictions of the AR mag well prohibits the thickness required to allow a reliable clear plastic mag. (AUGs use MUCH thicker translucent plastic in their mags.) With present technology, clear plastics is < colored plastics < black plastics is the rule. I believe even Magpul recommends their black mags are stronger than their “other colors” mags.

    I don't know about your intended 300 Blackout use. YMMV. Good luck, but test those mags if you intend any serious use.
