Hello all,
New to the site but not to shooting, reloading, or ARs in general.
I'd like to use these magazines:
https://www.cheaperthandirt.com/product/c-products-defense-ar-15-30-round-magazine-223-rem-556-nato-no-tilt-follower-aluminum-gray-3023002179cpd-766897411083.do?sortby=ourPicks&refType=&from=Search:
but I'm having trouble searching the site and finding a reliable tutorial for converting these to 13-round .450B magazines. Should I mill the follower as-is? Replace it? Add a single-round follower adapter and reduce to 10-rounds? (clearly the last is the least desireable option to me).
Thanks!
