Converting a 30 rounder to a 10 rounder

[ChillyWilly]

Hello,

Can anyone help me with this. I want to get a built VZ58 but I am finding that getting 10 round mags is impossible. What are my options other than moving? Can I bring in 30 rounders in as parts and modify them to 10 rounds? Is modifing magazines a common thing that I can pay someone to do? If so who? Is it something easy? If so I am mechanically inclined and very adventerous.

Thanks for all your help

Jerry

Search, a lot has been covered on this topic. I'm currently sending a letter to DOJ about this very subject so I can get something in writting before I act. The biggest problem you'll run into is the definition of "permanant" when modifying a magazine. If/when I choose to do a mag mod I'd use a rivit + weld to really cover myself. Also I haven't seen anyone or anystore offer to modify mags because the money they make compared to possible trouble isn't worth it for them. IIRC there is a member or 2 on here that have modified mags for other members but they haven't offered it as a service, kinda on the side type deal.

JPGlee routinely offers his services for mag conversions.

A word of caution on converting the 30 rd mags. Be carful how you deal with the remaining void in the 30 rd mag body. There is a large void in the mag, unless filled with permanent object or the base plate is welded on. That void could "hold" ammo and I was told that the ammo can be held in any portion of the magazine and considered in the rd count, even if physically impossible to be chambered from its position ( lower storage area). Maybe he was just shinin me on.

So my 1.5 cents... if you are gonna convert... fill that void, weld that floorplate, or leave the floorplate off.

If it doesn't feed, it's not an ammunition feeding device. That's what's limited to 10rds.

I am hoping to have them cut and welded anyways....too many uninformed lookey loos....and I don't want the hassles....

need to cut the spring, and weld in some kind of a cross pin to keep the count from going above 10.0, not 10.5 rounds .

but do not bring in any mag holding more than 10 rounds.. a parts rebuild kit is good to go.

Do NOT cut the spring unless you're planning on cutting down the entire mag. Restricting the follower or seating of additional rounds does not require (and would fail to work) with a cut spring.

10.5 rounds is fine - it's 11 rounds that's an issue.

Cutting is exactly what I would like to do. I don't want to get hassled so I want everything to be visually obvious as compliant and legal.

You guys mentioned rebuild kits, is there something special that makes a magazine a "kit" or not or does this simply mean a completely disassembled magazine?

yeah... rebuild kits is the colloquial term we use for a disassembled mag.

Is there a tutorial somewhere on how to create a 10 rounder from a 30rd kit? I see there are 10/30 ones online for $25-$35 but if I could use a rebuild kit and make them myself I'd save a bunch of $$$ for gas.

I will teach you how to make them for a thousand rounds of 5.56
