Disassembly of CZ 452 Magazines

Any smallbore range across New Zealand will have a few CZ 452 magazines floating around. Whether they’re attached to a Brno Model 2 or Norinco JW-15, these magazines hold up to thousands and thousands of rounds being put through them. Occasionally – you might even think about cleaning them.

How often to clean your CZ 452 magazine

Simply put, not that often. There’s lots of discussion around how often you should clean a rimfire rifle. Some like to clean after every trip to the range, but I personally prefer not to clean that often.

I find that that once a rimfire barrel has been fouled it shoots more consistently. That’s my experience anyway. Cleaning every trip undoes this fouling and means wasting ammo before every shoot getting it fouled again. So, when do I clean? When accuracy drops off, or when feeding becomes slightly tougher. Usually, the latter strikes first.

I take the same approach to my magazines. I clean when feeding becomes an issue. I usually use multiple magazines and consequently they don’t get fouled that quickly. If I haven’t had any issues by the time I give my rifle a birthday, then they get a clean too. Might as well.

Disassembly and reassembly of the magazine

Pulling apart the CZ 452 magazine is very easy. They’re well made and there are no sharp parts or difficult processes involved.

At the base of the magazine there is a small dimple. Inside here is a spring loaded button. Press is down with a pen, nail or punch and slowly slide the base off the magazine. I say slowly because if you’re not careful, the spring will shoot that little steel button out. Good luck finding that again.

To get the spring and button out, cover them with your thumb while you slide the magazine floor off, and slowly release them into your hand. Next, pull the main magazine spring and the follower out. Take note of which way the follower is facing – it needs to go back the same way.

Cleaning is simply a matter of wiping everything down. You can dowse the spring and follower in Hoppes No. 9 if you like. A quick squirt of gun oil once everything is clean and dry isn’t the worst idea either.

Assembly is pretty easy, it’s the exact opposite. Again, be careful you don’t lose the spring or steel button.

Because CZ and Norinco mags are quite common, I marked mine with my wife’s red nail polish to make them easily identifiable.
