Several years ago I gave my sister-in-law a CZ 527 in .223 Remington cal. Over the ensuing years the magazine has been mislocated. She fessed up and asked me to help her find a replacement.

Anybody have a line on a source? Everyplace I’ve tried is out of stock on them.

Try these

Not sure if you want 3 or 5 rd

What I did is I found the sku on Midway (out of stock as you say) and then went on gun.deals and searched for the sku plus cz (e.g. cz 13003)

5 rd: sku = 13003 https://gun.deals/search/apach..._search/806703130033

3 rd: sku = 13008

Thanks Jimbo. Looks like the two more reputable sounding purveyors are also out of stock for the 5 round mags.

I got a warning on the “Cheap Ass Ammo” link and didn't open it.

Check ebay, $70. Just search for CZ 527 .223 Magazine.

I have recently purchased from here with good results. Shipping didn't take to long.

Thanks Mettlepig-out of stock there, too

A guy over at the MGO forum has one for sale

Have not ordered from the site before.

^^^ I have - definitely good to go.

If you haven’t already, sign up for in-stock notification at Brownells. Picked up 2 for my 7.62X39 this week.

My first go to for anything 527 (I don't ever need things like mags in stock) is CZ USA. just put in a notification and you will get them eventually.
I know that doesn't help if you need one -right now-...

Never bought from them but show as in stock

I have used them a couple of times with no issues.

I have ordered from GunMag Warehouse many times and had excellent service. Their notifications are good for getting scarce items, and the one time I received the wrong mags in error, they gave me a return label and I got the replacements as fast as their shipping made possible.
