Centurion Arms Gen 2/3 AR15 PMAG Extension

***It is the responsibility of the end user to make sure that mag extensions are legal to purchase/own in your state/area!! ***


These 5.56 PMAG extensions work on any 5.56/.223, 30 or 40 round, Gen 2 or 3, PMAG magazine (we cannot guarantee fit on any other mag.) These extensions add 5 extra rounds to a PMAG 30 round magazine and extra 6 rounds in a 40 round PMAG magazine. Extensions do add a little extra weight to the magazine and helps the empty mag drop free easier for faster reloads. They will give you more ammo and therefore an edge over your enemies. The base pad itself is machined out of billet aluminum and is Type III Hard Coat Anodized to ensure durability and a long life.

- Works with stock spring.

- Overall weight 2.1oz.

- Added length, 1 inch.

- Easily attaches and detaches from the magazine.

- One piece design; no small parts to keep track of.

- Minimal length addition to allow usage while in a prone position.
- Holds 35+1 rounds on the PMAG30.

-Holds 46 +1 rounds on the PMAG40.
- Manufactured in the USA.

    Pmag extension

    Received items quickly. Not something that always happens when getting items shipped to Alaska. They look and feel quality. I am also extremely pleased with the communication with this company. Emails are answered quickly.

    Great design, execution and value

    Super simple install. Nice machining and finish too. Always top shelf from CA and the owners are both fantastic people always deserving of my money and support.
    By the way, on a 40 I gained 7 rounds. I'm not leaving them on any of my 40s but I just wanted to see what increase they gave and all of my 30s are currently loaded but that's where they will eventually go.
    Thanks Monty and Corrie.

    Best Aluminum Mag Extensions

    I prefer these over the most popular ones made by "TTI". These are: base price, about 10 bucks less than the tti, and more importantly, much more simple in its design. These use a singular, regularly sized screw that directly stops the extension from backing off the pmag. Tti uses a set screw and pin, I feel these are a stronger, much simpler design.
