I need some help, here - I thought their 20s for the 5.56/.223 were curved?Lancer sells a straight 20 polymer mag. Its constant curve geometry inside and is a nice mag.
All of my L5AWMs are loaded to 30, and this is how I typically load for training classes - even those that insist on closed-bolt administrative loading. I've honestly never had an issue in any of my range/training guns (LMT, BCM, BAD, UCWRG, Aero) or with my HD-gun (DD). My understanding was that it was only a certain batch of the 30-round L5s (and I would guess that it's that same time-period's 20s, too, as my 20s also go the full way and can be easily loaded bolt-forward) that saw the seating-on-bolt-forward issue, and indeed, the fix was to file/shave down the limiter. Did this become an issue yet again? I almost want to say that the limiter issue was c.2010-2011?They do have limiters built into them that make it hard to load 20 rds on a closed bolt. You need to shave this limiter down if you ever plan to load 20 rds into the mag. In fact, that applies to ALL Lancer mags, 20 or 30, they all have pointless limiters built into them that need shaved down
That said, I download to 28 for my daughter for range-use as well as with for HD, as she has trouble inserting full 30s on closed bolt: and this is regardless of magazines used (that was actually the first thing I tried for her).
