Was at a local "surplus" store today looking for an ammo can and stumbled across something interesting. Airsoft guns. Plastic toy guns.

Now why the hell would I care about that now? I'm not much of an airsoft guy, prefer shooting the real stuff.

Wait, whats this???? DMPS makes magazines for Airsoft AR15s. IN METAL!!!??? :runaway: Now that gave me an idea, so I bought one. (Well not my idea, but others have done it before... but at least a cheap parts idea for someone elses previous idea....)

The above photo shows a standard USGI style 30 round on the left, and a DPMS metal airsoft mag on the right. Near the top of the airsoft mag you can see a little pin. I punched that out and the entire "motor" for the airsoft pellets lifted out. This left the empty hull of what looks identical to the bottom of the USGI mag. The floor plate is even slid on the same way on the airsoft mag.

So I did some side by side comparisons. It is almost as if DMPS just cut the feed lips and a bit of the top off a standard mag. Eventually I just taped a LAR mag to the side of the airsoft mag to get a proper length figured out...

Marked and cut.... then set them up to see how close they were....

I then went to work and sacrificed a "Mag-Wedge" brand metal coupler (wouldn't dare do this to the nicer Dlask ones...) and did some back and forth test fitting...

I got them fitting tight enough that I was able to drill a hole in the front edge of the airsoft "husk" to use the front retainer screw on the wag wedge. I then drill a hole in the back edge and used a small but solid enough screw on the back drilled into the modified mag wedge to secure it all down.

Little bit of tape for the edges...

All in all it is super snug, feels like a proper 30 round mag and cost me $25 in parts ($12 for wedge, $13 for airsoft mag). Might even be able to sell the old guts from the airsoft mag to cover some of that hahahaha. :dancingbanana:

Ya I posted right under your post in that thread. Never saw any mention of a source for the extension though, and was surprised to see DPMS making the parts needed to do it. Better to cutting up airsoft parts than real USGI mags in this market, or ANY market for that matter.

I couldn't remember which CGN'er had posted it before but I had the pictures saved. Made sure not to take credit for the idea in the post, it sure isn't original on my part.

Just giving you a hard time, nobody owns any intellectual property rights on chopping up mags.

I did use real mags though. I collected some that were going to be binned for failures and chopped them up. They were all free or close to it.
 
I tried an EE ad for mag bodies some months ago. You'd think I was asking for IED plans. Had one member even PM me saying "its obvious why you want them, you may want to take the ad down before some one zeroes in on you for trying to make a prohib mag" hahaha.

I'd prefer free reject mags but the $13 ain't so bad.

Huh? If I want prohib mags I can get them by drilling out a rivet! I don't have to buy mag bodies. Someone judging you by themselves sounds like!
