Product description
Highly Reliable 20-Round Magazine Designed Specifically for 300 BLK Rifles
The Magpul PMAG M3 20 Round – MAG1182 is a dedicated and highly reliable polymer magazine designed specifically for rifles chambered in .300 AAC Blackout (300 BLK). This PMAG is more compact for increased maneuverability and creates a more concealable package for use in small format firearms.
300 BLK in the past has been known for its compatibility with 5.56x45mm magazines. However, many subsonic loads with longer projectiles can have feeding issues with traditional 5.56 magazines and this magazine solves that issue, providing shooters a true .30 caliber AR magazine that functions under the constraints of the existing AR-pattern dimensions.
Incorporates The Features & Performance of the GEN M3 Magazines
The Magpul PMAG M3 20 Round offers a safer, more reliable way to feed a 300 BLK rifle with a distinct ribbed design and smoother upper-half texture that provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate dangerous cross-loading issues.
Along with its optimized 300 BLK performance, the PMAG 20 incorporates all of the GEN M3 features, including the next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, a paint pen dot matrix for marking and identification.

AT3 Tactical · Thank you for the positive feedback! We are glad to hear that our product is working well for you and your rifle. Happy shooting!
However, my cartridges using the Maker 200 gr. bullets noticeably drag inside the magazine well of the PSAs but still work, while the Black Rain magazine well is apparently smaller inside and makes the Magpul 556 magazines unusable with this bullet profile.
These Magpul 300BLK specific mags all work well with all bullet types in both receiver brands.
