The next-generation PMAG 30 GEN M3 is a 30-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.

While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified internal and external geometry also permits operation with a range of additional weapons such as the HK® 416/MR556A1/M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others.

Similar to the MOE PMAG, the GEN M3 features a long-life USGI-spec stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly to ease cleaning.

In addition, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. The new, easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches. An included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.



  • Next-generation impact and crush resistant polymer construction
  • Modified dimensions allow for wider compatibility with non Colt-spec platforms
  • Constant-curve internal geometry for smooth feeding
  • Anti-tilt, self-lubricating follower for increased reliability
  • Long life USGI-spec stainless steel spring
  • Over-travel insertion stop on the spine
  • Ribbed gripping surface and new aggressive front and rear texture for positive magazine handling
  • Paint pen dot matrix panels on the bottom of the body to allow for identification marking
  • Flared floorplate aids magazine handling and disassembly yet is slim enough for use with many double and triple pouches
  • Pop-off Impact/Dust Cover to minimize debris intrusion and for ammunition protection in storage and transit

308AR Magazines

308AR MAGAZINES for the AR-10 and DPMS LR-308:

Be sure to follow our 308 Magazine discussion on the forum


The MAGPUL LR20 308 AR Magazines are simply the most reliable magazine for the DPMS/SR25 platform based weapons. If you have a DPMS that doesn’t feed and function properly these magazine will eliminate a faulty magazine. I cannot attest to their durability as they are relatively new to the market.

At $20 they are a steal.


To the best of my knowledge the only magazines available for the Armalite AR-10 are manufactured by Armalite. MAGPUL PMAGS do not work in the AR-10 platform.

Armalite takes some heat from the uninformed about their magazines. During the AWB Armalite switched to modified M14 magazines and initially there were some feeding issues. Today this is not an issue. The magazines and weapons function perfectly. In fact if you have an AR-10 made during the AWB period Armalite will upgrade it to the current standard for use with standard Armalite AR-10 magazines for a nominal fee.

Magazine cost was another factor detractors of the AR-10 platform would oftenbring up. Current AR-10 magazines are sold for about the same price as DPMS factory magazines.

Lastly Armalite offers 25 round magazines for the AR-10. No other 308 AR manufacturer has been able to pull that off.


If you want steel magazines for any DPMS/SR25 platform based weapon DPMS is yor best bet. Now here’s the thing. A couple years back DPMS had a bad run of magazines and they are still out there. You can tinker with them to make them work or call DPMS and exchange them. DPMS is pretty good about it. Also keep in mind DPMS still lets out the occasional bad magazine. The prior sentences apply. If your nor sure you have a bad magazine buy a PMAG and eliminate that variable.


ProMag is a newcomer to the 308 AR field. Typically ProMag makes premium magazines but to date there is little information available. If they prove reliable priced at $29 they will be a great alternative to factory DPMS 308 magazines.


I have no idea who these guys are but reviews are less than favorable at online stores. We also have a discussion over at the forum. At nearly $40 they cost more than DPMS factory magazines and twice as much as 308 PMAGS.
