Thread: Modifying Norinco JW21 tube mag

So, my youngest has the above 22 lever action.
Holds 12 rounds of 22lr
Whats involved with decreasing the mag capacity ?
Cheers

the easiest way is to lengthen the follower in removable tube are you going to do it yourself either braze say 50mm of rod onto the end of the follower make sure its straight and round the edges other way if your that way inclined is turn one up on a lathe

My understanding is that if you take it to one of the governments “approved” gunsmiths they will do it and it’s paid for buy the buy back fund. I was speaking to our local gunsmith and he said he’s done over 60 of the tube mag mods all invoiced to jacinda

Or this just depends if internals are plastic as well

Its a fairly simple task if you have the gear - pull the mag tube out , un-pin the end cap , pull the spring out , make a 5mm rod of the length of the number of rounds you need to lose , silver solder that to the internal end of the nose cap , slap it all back together.The spring needs to ride happily over the internal rod.

The Law states plainly " a magazine capacity of not more than 10 rounds." Thats it - no how or what method or prove it to me .

Alternatively you can roll a ring crimp into the inner mag tube at the point of ten rounds down the hole. Use a modified tubing cutter with the edge ground off the cutter. Dont go too deep - just enough to prevent the follower passing inside the tube , too deep and you will impede the spring travel inside. This you can do without pulling the mag tube apart - but it looks ugly to me .

Yes you don’t have to take it to an approved gunsmith but what I’m saying is if you do, they’ll do it at no cost. If you go to an unapproved Smith then you’ll pay for his service

And your volinteering your rifle to be one of the first to go on the new register

Yup I wish I still had access to machinery otherwise I would've done the job myself. Other stuff going on, not just the magazine. That I could've done all by itself.
Its a moot point though if registration comes in. They will all be on the books

Sure they will just like every naughty gun will be handed in.

what if you just drilled a hole and riveted it so it couldn't hold more than ten? may be a bit ugly but you could cold blue it.

Probably interfere with the spring
