So far I've come across 5 and 10 round AR magazines in Legend 350 in gun shops made by CMMG and Duramag and 15 rounders for online order made by Wilson Combat. The CMMG and Duramags look like they could be made by the same manufacturer. They worked well but appear to be rather flimsy. I haven't had a chance to check out the Wilson Combat versions but I'm guessing they are better made.
Anyone find any feedback on quality made AR magazines for this caliber, especially in the 15 round and up versions?
