Rifle wont accept pinned magazines :( Suggestions?

[D 23]

Rifle: Rem R-25 (closest to DPMS LR308)

When I bought this it came with two DPMS 4/10 magazines that were blocked as opposed to pinned.

Basically two pieces of plastic glued to the front and rear walls of the magazine.

I recently bought 5X 5/20 round DPMS magazines that are pinned.

Problem is, the pin makes it too tight of a fit in the mag well. I can get it into place to seat with a bit of effort but it won't eject without a lot of pulling and wearing on the rivet and the rear of the mag well.

So, can I block these with plastic blocks similar (obviously longer) to the ones in the 4/10 mags and pull the rivet or would I be doing something bad?

Don't want to grind the lower obviously.

Could dent it in so it clears but, would rather block it if it's not going to cause any "problems" down the road.

Generally what happens on nice mags is that you get countersunk rivets. I bet that would fix your problem here.

I noticed between my basic p-mags and the Gen 3 pmags I got from CTCS, the new mags the pin is recessed slightly rather than protruding out.

Unfortunately I don't know how to go about doing that myself. But I'll be someone on here dones!

Could you possibly file a bit off the rivet? That usually works for other ARs.
Alternatively, yes you can use an internal block so long as it is a "permanent" alteration and requires a "tool" to remove.

I think if I file enough of the rivet off it's going to pop out. Really tight in there.

As long as my gluing plastic strips and then removing the rivet is legal, I'll go that way.

File down the rivet.

i have mags that are riveted at the front and some at the back.

Filing solved all issues. Paint if needed.

My neighbour had a PMAG with an issue, but filing would have broken the rivet.


He used a heat gun where the rivet was and counter sunk it by pushing on it. Works flawlessly, no damage to the PMAG.

To counter sink a rivet just use a drill with a drill bit the same size as the rivet head and put it in reverse. That way it won't dig in and will slowly chew out material. Works better on plastic mags, depends on spine thickness on metal mags.

I had issues with my AR15 and Pmags being too tight, to the point of scratching the mag well inside and mags not dropping free, countersunk and reriveted and now it functions properly.

Disassemble the mag.

Remove rivet.

Counter sink with drill press with a stop.

Re-Rivet.

Done.

But, but, but until you put the new rivet in, you possess a prohibited device! Better wear your tinfoil hat while doing it...

Get a big stop watch that goes "tick tick tick" while you do that part. Make sure to wipe your sweaty brow. Trembling hands is optional.

Thanks for input guys.

My first thought was even your rifle resents our neutered canadian mags haha

After you have drilled out the original rivet just countersink the original hole. Go slow and test fit the countersunk rivet till it is flush with the mag body. Then pop rivet it in. Remove just a little bit at a time and you won't have any problems. Metal mags are folded at the rear so there is at least a double thickness of metal so countersinking the rivet hole works fine for them as well.

BTW Canadian Tire sells the rivets you want. Countersunk stainless steel 1/8" rivets for about $6/100.

Don't Use Stainless!!!!!!!!!!! they are a pain to take out, they heat up and start spinning cause they melt the pmag. get countersunk aluminum blind rivets from fastenal. I learned this the hard way. also it helps to practice countersinking on a piece of scrap plastic with a few rivets.

if u disassemble the mag into parts.. then wouldnt u just be doing some "metal work" on parts and not a functional mag?

There have been posts on CGN about the mag body being the prohibited device even if the other parts are not there.

never heard that before, that would be something to look into.

I am so glad that our 5 round limit is saving lives by not allowing magazines to fit in the rifle....

Chances of police executing search warrant while you have mag disassembled for the 3 mins it takes to countersink and rivet?.. you'd probably have the same chance of winning the lottery, getting struck by lightning on the way to cash it in, then having the ambulance transporting you flip over crushing vin diesel who was walking by while the side mirror flies off into the air striking a news helicopter making it crash into a school bus full of nuns on their way to the spa.

Now if you leave them unpinned for long periods of time..

Isn't that the goal...... Lol

I've replaced many SS rivets & never had a problem taking them out. Just make sure you use a nice sharp drill bit.
