thought it would be cool to trow in this magpul follower i have laying aorund and maybe a ranger plate on the bottom BUT the bottom looks as if you cant dissasemble it? theres no hole in the floor plate like standard ar mags and there isnt even the 4 folding tabs to hold the bottom on it has a plastic plate that says bush master on it.

heres a pic of what type of mag it is:

No reason to do it. Those mags run perfect.

Before you try this be aware that you may destroy your mag. It would be a shame too because those mags are very reliable and they dont make them anymore.

Basically, theres an indentation on the baseplate close to the logo. You drill it out, in it is a pin that locks that plastic button on the side of the mag in. Pull the pin, remove the plastic button (for lack of a better term) and you can remove the spring and follower.

Yes they can be taken apart, and no it does not destroy the mag. Just be careful. Search for threads started by me...:)

If you want a mag with Magpul followers, I've got 10/20 Pmags, C-Products and Steel ProMags I'd happily trade with you... all 10/20s.

Those are still the best 10/20s made... yes, better than Pmags.

dont get me wrong it has been a fantastic mag and has worked flawlessly! i was just board last night and thought well i have this stuff laying around mine as well slap it on and just to burn a little time. but i dont want to drill and do this that and the other. i'll just wait till it actually needs to be re-built someday. didnt even know about these mags and i had bought a lower that had it in there (best deal ever a complete JP lower with a JP buttstock, Jp trigger and this mag with a prince 50 for $350!) and just tried it one day and was shocked how well it worked cause i have some 10/20 pmags and have had a few hicups with them and those were new from rifle gear!

sorry if this was posted in the H.G. section my mistake!

These are 5 rd to 10 rd conversions, but you get the idea.

Standard 10 rd floor plate:

Thanks BLFD1! btw where did that little roll pin come from? so i take it you drive that pin through the side of the mag out. then drill the hole in the bottom?

No, The pin is held in with Epoxy in the bottom of the floorplate. Scrape out the Epoxy, bang out the small pin and the large pin slides out the side... viola, the floorplate slides out. :D

Look at the bottom of the magazine. There should be a SMALL round mark in front of the snake logo. You can see it in this picture posted earlier, just below and to the right of the R logo.

Drill out that small circle with a small drill bit (it's not very deep, maybe a 1/4" or so) and you're done. Turn the magazine right side up and smack it against something, like your hand or a table top. A small retaining pin will come out. With that retaining pin out, you can push the cross pin, that goes through the magazine, out (putting upward pressure on the floor plate may help). After that, the floor plate, spring, and follower will all come out the bottom. Replace the parts you need to and replace. You might want to add a small bit of epoxy, glue, putty, etc to the retaining pin hole so that it doesn't come out and dump your magazine while using it.

there are suppose to be extremely reliable and dont fail etc. they are suppose to be the ar mag out there but they dont make 10rd mags so in ca. they are kind of the "holy grail" so to say.

You do know that H&K mags are marketed at the military, who don't repair their magazines, right? Their springs have been reported to fail as early as 5k rounds and H&K (or anyone for that matter since, as I understand it, the spring is special) doesn't sell replacements or offer them to people that ask directly. They also have a nasty habbit, from pictures I've seen, of HORRIBLY failing when kept fully loaded for an extended period of time. And that's doesn't even take into consideration that they are heavy and don't work with all magazine accessories.

Don't drink the kool-aid, go read about them from places that aren't fan boy sites.

ETA: And so you know that I'm not talking out my butt here is a picture. And before anyone points it out, YES, this particular picture is of a magazine loaded with 5.54x39, but its been reported that it happens with 5.56x45 just as frequently.
