What is the MEAN ARMS - AR-9 ENDOMAG 9MM 30-ROUND (3 PACK)?

Several companies have developed 9mm conversion systems designed for use in standard AR-15 lowers and uppers. However, feeding a 9mm magazine through a standard AR-15 magazine well presents some issues. Typically, this has been solved by the use of magwell inserts, but Mean Arms tackled the issue with a different take: why not change the magazine itself? The Mean Arms AR-9 Endomag Conversion Kit takes any standard Gen 2 or Gen 3 Magpul PMAG and allows it to be converted to feed 9mm rounds. The conversion is built for use with Glock®or Colt 9mm bolt-carrier groups. The kit comes ready to convert 10-round magazines, but it can be modified to fit 20- or 30-round magazines. No magwell adapter is needed for use with the Mean Arms AR-9 Endomag Conversion Kit, and the company ensures reliable performance with all brands of 9mm ammo.

Reviews Summary
The AR-9 Endomags conversion kit has sparked mixed reviews, with many users praising its affordability, versatility, and effective design on compatible builds. However, notable reliability issues, specifically jams and feeding problems, plagued several users, often linked to its plastic ejector. Overall, it offers potential but may require careful setup and adjustments for optimal performance.
What Reviewers Are Saying
Reliability and Performance
45%
A significant number of reviewers expressed frustration with the Endomags' reliability, reporting frequent jams and difficulties in feeding rounds. While some users experienced flawless operation, these issues were prominently noted, indicating that proper setup and compatible parts are crucial for consistent performance.
Ease of Use and Installation
60%
Many customers appreciated the straightforward installation process, finding the conversion kit simple to integrate into their existing setups. The ability to use standard PMAGs for a 9mm setup was also seen as a major advantage, adding to its practicality for builders on a budget.
Design Concerns
35%
Several users raised concerns about the materials used in the ejector, describing it as flimsy. This aspect has led to worries about the long-term durability of the product. While some were satisfied with its performance, others felt that a sturdier ejector could improve reliability.
Value for Money
55%
Overall, reviewers found the Endomags to be an economically friendly option, particularly for those looking to convert existing AR-15 lowers to 9mm. Consumers noted that the price point saves money compared to purchasing proprietary magazines, reaching a good compromise between cost and functionality.
Satisfaction with Adaptability
50%
Users highlighted the convenience of the Endomags in terms of adaptability, allowing for easy switching between calibers without the need for extensive modifications. This feature appealed to builders who want flexibility in their firearm configurations.

Awesome Magazine Conversion
Endomags are the best choice to feed your AR-9! They are reliable and fit perfectly into PMAGs. Although I use them for 30-round configuration, I only load them to 25 rounds as they sometimes won't feed properly (at least in MY AR-9).

Great product still needs work.
This is the best product I could find out there for using a standard 15 lower with a 9 upper. Needed an ejector. The Unser clicks in and is solid. The ejector sits on top and is a little flimsy feeling. I super glued it to the mag and it is strong now. I wonder how lone plastic will hold up to being an ejector but I guess we will see.

AR9 conversion mag
I purchased the 3 pack and so far ran about 600 rounds total. Not one malfunction. I just ordered some pmags in coyote tan and will dedicate that color for 9mm only. This way I will know which are for what. So far so good, there great.

right on target
Just wanted to try this out before I paid much more for a different adapter for 9mm. After converting the pmag in was very disappointed, this thing just didn't work. Then I tried a new bcg from spinta precision BOOM every round down range. The only difference that I see is that the bcg has a larger steel weight than the first one I tried Endomag is much more affordable and with the correct components wow!
