Rebuild tips for AR15 mags?

[MK11]

I'm going to redo the guts in a few cheapo AR mags and worn-out GI mags that could use an upgrade. Any tips on what springs and followers to use?

I see Cheaper Than Dirt has a $9 AR mag rebuild kit complete with several springs and green followers and floorplates but having been burned by them before, I'm leery. Has anyone used this kit?

OUCH!!! Even Bushmaster isn't that expensive:

My opinion is that you should not refinish your magazines. If you decide to, get some Dry Film Lubricant to do it and do it right. Don't just paint them.

Tapco has a good deal on 10 new green mil-spec followers, 10 new springs, 10 new mag dust covers along with a "haversack" for $29.99.

I sent my mag bodies to [email protected] . He refinished them in Norrell Moly "HK black" for $5 each. They look better than the black Teflon coated DPMS mags I bought back in '94.

Just for the sake of doing it, I may buy a couple more mags at the next gun show and try Brownell's AlumiBlack on them. I kept reading on AR15.com that it would flake off, but then some guys from FALFiles posted that it took 3 WEEKS to cure properly, and that it wouldn't flake off after that.
