Stocking up on magazines -- what capacity?
 

...

I would say a mix since you're moving. If you don't take a 30 round out in public, how could they ever know you have them? Keep those at home and take the lower capacity ones to the range. I just picked up a 30 round Magpul AR magazine for $14.99 at Cabelas.

Can you put a plug in the 30 round version to limit it to 21 rounds? 15 round in a rifle is BS.

Brownells has a good price on a qty. of 10 (Pmag 30's)...

As big as you can find. I'm sure a lot of the restrictions in your area were knee-jerk reactions to Columbine - not unexpected. This administration will be looking to crush private gun ownership and in particular ammunition and associated items like clips, drums, etc. I've been loading up (no pun); living in one of the few remaining states which actually seems to uphold constitutional principles helps but even this state is starting to circle the drain down the liberal/socialist cesspool by electing a rabidly anti-gun governor. On the upside the pending permit less concealed-carry law in the legislature probably still has a veto-proof majority so I hope it gets through soon.

These are dark times for the Republic...

If you keep your high-cap magazines dissasembled, they aren't magazines, they're repair kits. At least, that's the law here in Cali. For example, for an extra dollar, Cole's will covert a mag to a repair kit before shipping it here.

I vote for staying in AZ or any other state that respects the Constitution. But if you must, Magpul makes very good 20-round magazines. I have a few simply for use with my varmint AR--less likely to interfere with shooting off a bipod on uneven ground.

I usually buy 30 rd. P-mags in batches of five for under $60 delivered.

Why are you in the Northeast?

Maybe he likes the cold weather? Shrug.

30 rds for home
10 or 20 rounds at the range... the 30 is just to tall and get's in the way when shooting prone.
