[ARCHIVED THREAD] - how would you alter a rifle magazine to function reliably but only accept 10 rounds (Page 1 of 3)

Posted: 1/18/2013 1:34:43 PM EDT

Some of us may actually want to go the range and not dump all our magazines in old mortar cases in our sewage tank

ps let's get this out of the way

1-move

2-commence violent overthrow of NY

3-ha ha tough luck for you

4-you are a pussy

I'm not the smartest but don't magpul make mag limiters for both the 30 and 20 to reduce them to 10 rnd capacities?? Or is that still against the new laws?

Not ever having lived under communist rule, and therefore never owning a 10-rounder, I was always assuming there was some sort of different base plate that extended up into the magazine so that it would not hold more than 10 rounds. I can't imagine one pmag being all that different from another pmag except for just a part like that.

Or I could be making it up while divulging a great new business opportunity.

ETA: What that guy ^^^ said. Damn I'm a genius.

At least we will never see anyone from NY ask about wearing out mag springs from storing them loaded.

Same concept as limiting a shotgun. If you want to make it "permanent" (at least as far as a quick inspection goes), try a piece of lexan that you JB weld to the base. It goes inside the coils of the spring & stops the follower at the point you cut it to.

Had to do this to a Ruger P85 magazine a long time ago in HI. Worked then, don't see why it wouldn't work now.

Yep.

Or Exile Machine sells a product called a magblock that does the same thing.

I would think this would do the trick, but would it be considered OK?/?

You trade them to someone, like me, in a Free State and we purchase and give you 10 rounders.
That way, everyone is happy. No need to alter.

Interesting Aimless.

Your question implies you believe this may be an acceptable modification.

I think I would go with a plastic or aluminum post / rod, and a tiny spotweld on the baseplate so it is not readily reversible without tools

I think we can only buy 10 rounders legally until sometime in April and they are all out of stock. Sure you could smuggle them in as long as they are not new production but COC and all that.

This is what I use to block mags, they are cheap and fit perfectly.

Measure where on the outside of the magazine the new floorplate would have to be to only accept the spring, the follower and 10 rounds.
Remove the guts of the magazine.
Insert a block into the magazine sized to fit to the line drawn on the outside and slide it up to the feed lips.
Place magazine on anvil.
Hammer magazine flat below line.

Hey Aimless they're in STOCK TOO!! Better get them before the rest of NY gets to it. Here is the 5 rnd limiter for when ya'll go completely bat shit stupid!

Im imagining some type of snap-rivet through the body of the magazine which stops the follower from passing.. it would be ugly because it would have to impede the spring also.

Good to know.

I was also considering hiting up Alexander Arms for a bunch of beowulf followers and baseplates too if they have them.

You can make a block that will sit inside the spring coils, that limits the follower's downward range... Basically, load the amount of rounds in you're limited to, then use something to measure how far down the follower is into the body - that'll give you a pretty solid idea of how tall the block needs to be... then length and width are determined by what will fil inside the spring coils...

You can also look at the stickies on the Calguns Gunsmithing forum for instructions on how to make your own blocks.

Rivets on each side of the mag.

Leave the springs alone. Just stop the follower from traveling downward past 1,2,3,7 or whatever fucking count du jour.

Thank God I live in Alabama. I'm too lazy to engage in such crap.

Just don't load more than 10 rounds at a time, should function fine, hold 10 rounds, and require no modification except for the SOP of loading your mags.

Another variation on that would a proper length of tubing that you then thread on one end, drill a hole into the bottom of the baseplate, then bolt it in from the bottom...

I've done it in the past to make "hunting legal" mags, and it worked reliably... If you're still in my area, I can help you out with that if you want...

Take a road trip to MA. They still have them in stock. I just spent $260 on 10 rd mags in case the MA legislature goes full retard just like duvall.

For a GI mag, figure out where the follower needs to stop to accommodate 10 rounds. Break down the mags and use a hammer & punch to create a new "follower stop" on one side of the mag body.

Also, #4.

Just a guess, but I'm *thinking* you may be able to block a few for legal use, and disassemble the rest for later - after all, I don't see "parts" as being illegal...

Ghetto rig would be a 4-40 machine screw thru the mag at the right height to limit the mag, add green (seizing/permanent/would have to melt the follower to get it off) loctite. Would work on AR type mags....not so much for pistol mags.

I blocked off Saiga mags so I could be super legal eagle for duck hunting by using plugs made of plywood. It fit inside the coils of the springs and till reliably feeds, just at 2 round capacity.

As has been already said, the guys over on calguns have got the "10 round modification" shit down. They've also been exceedingly clever with things like bullet buttons and monsterman grips.

What remains to be seen is if NY interpretation of NY laws will follow CA interpretation of CA laws. What passes as permanent modification in CA may or may not pass as permanent modification in NY.

Magpul has the 10 rounders coming out. Who knows when. That's what I'm going to use for my 1 California compliant rifle. I did see a few places that had 10 rounders in stock.

I'm not anywhere near patient enough to figure out how to mod any of my standard cap mags to take 10 rounds without rendering them inoperable.
