Ever take apart a DPMS **PHOTO ADDED**

Panther Magazine? Do they come apart by sliding out the floor plate or by tilting the follower and pulling the spring out of the top.

Ive kinda experimented in both directions and doesn't appear either is going to work out easily. Figured its time I asked.

Also, Ive searched the AR15.com site, web searched and made a call to DPMS . You guys are my last resort, otherwise I will be calling DPMS back on Monday.

Help me...I need a hero!

I have not done the DPMS, but if you can post a picture of it, I know there will be more help.

Usually just a catch, kind of a pry over and slide out option.. I have a colt that was riveted...
 
I've never seen one that you could take apart through the top. Post a pic of the bottom of the mag and we'll be able to tell you.
If it's like a Colt/C Products, you just need to get a small flat blade under the front (beveled) edge to get the floor plate up over the rim and it will slide the rest of the way out.
 
I have taken one apart to see if the white plastic block would come out (factory R25 /DPMS), it didn`t.Just like Evil Lurker said the bottom slides off.
 
The Bottoms (floor plate) on the DPMS (Factory R25/DPMS) Mag's DO come off and you can tap the white plastic blocks out! I have done it on 6 Mag's and cut some of the spring off to make them 10 round mags instead of 5 rounder's.... There is not a (metal) AR mag that the bottom wont come off.
 
every magazine in my time comes apart from the bottom. Actually this will probably be long past my time.

If your follower will come out of the feed lips ya got a problem for sure.
 
Hope this pictures works.

There is a hole on the bottom. Need to know which direction to remove the bottom plate. Closest to the hole there is a small tab on the magazine side that sticks up and blocks the center 1/3 of the floor plate.

Farthest from the hole, the magazine floorplate sits on top of the magazine bottom. Problem here are two "detents" that catch the edge of the magazine to deter removal.

Appreciate some experienced advice here. Thanks!

The floor plate will disengage and come off right to left. There's something very strange about that design, though.
The retainer "punch" detents are reversed to any I've ever seen, and the hole isn't at the correct end to help you with disassembly.
Every mag I own, the "rib" on the left side of the mag body is beveled and the floor plate bends down to meet it.
Being that strange, it's possible they also welded the floor plate to the body. Do you get any movement between the plate and mag body when you pry down?

Evil Lurker...I agree with you, a odd design. The only other AR magazines Ive take apart (Brownells) didn't take a lot of effort to pop the bottom off following the instructions in their video.

I don't get any movement of the floorplate by inserting a punch in the hole, no matter which way I pry.

I was able to "tap" a .013 shim between the magazine body and floor plate at the "detent" side. I could see the shim thru the detent hole, confirming that the perpendicular side of the detent will come solidly against the inside of the magazine. I would have thought that the sloped side of the detent would have been oriented toward the magazine such that the floorplate could slide up and over the edge of the magazine with "proper coaxing".

The right side of the magazine floorplate (as per my pic) has less play, probably because of the rabbit ears of the magazine bent over the floorplate, but I get no play in that side.

I don't see any signs of a weld from the exterior of the magazine, but I have tapped in both directions with a brass drift and havent detected any movement in the floor plate.

Not sure Im ready to try a "bigger hammer" approach yet.

You have to lift the OTHER END UP!!! and slide the floor plate in that direction..... insert a punch in the hole so you have something to PUSH WITH. if you cant get it off send it to me and I will take it off for you free of charge... the 2 indents are what is keeping it in place.
 
I'm stumped. Their whole design is exactly opposite of anything I've ever seen.

Why exactly do you want to disassemble it?

If it was me, I'd order some C Products mags and just use that one as-is, because if the floorplate isn't budging, you're likely going to toast it with the "pry and bigger hammer" approach.
But it's your mag.

Quote:the sloped side of the detent would have been oriented toward the magazine such that the floorplate could slide up and over the edge of the magazine with "proper coaxing".

See, that's the confusing thing. That detent should be made with the vertical "step" towards the magazine body. That way it butts up and stops, instead of forming a ramp (if you get my termiology). Then, it would have to be pried downwards to clear before it released.
The way it looks, dropping the mag might drive the floorplate out of lock.

Maybe I'm missing something.

If you are dead set on getting it off, hopefully without breaking off the retaining ears,,, Why not just drill a 1/8th inch hole in the other end of the base plate so you will have someplace to insert a punch and lift it up at that end...???

I will agree that it's odd for them to put the hole at the other end...
 

OK...got the first one off and developed a technique that I hope will help with others.

The floorplates slide off the "detent" end as you all suggested. Trying to be gentle I found a feeler gauge that would slip between the floorplate and the magazine, and fit between the detents. Little at a time I gapped it. When I hit .060 I could see that the detents would clear the side of the magazine.

Was easy then to lever it off with a punch in the hole.

Appreciate all your wisdom.

I didn`t try too hard to pull the plastic block out because I had some C-Product mags on order.I dont need to modify that one now, but out of curiosity, how much spring did you remove?
