Chip_Baker Posted March 7, 2021 Report Share Posted March 7, 2021 I just received my ar10 .308 with a Matrix Aerospace lower. I read a few discussions here about which mag feeds best with this lower. With so many suggestions it opened more questions than answers 😂 Some suggested magazines that they have but never used. So, can someone with this lower suggest a magazine type that works best? I know fit as well as how well it feeds is important. I am looking for a 30 round mag but just having a correct mag would be great 👍 Quote Link to comment Share on other sites More sharing options...
Chip_Baker Posted March 7, 2021 Author Report Share Posted March 7, 2021 🤔 I just found someone selling a Matrix Aerospace kit (upper, lower, and handguard). They are saying: "These receivers are designed to use highquality "P Mag" magazines." Not that I don't trust anything I read on the internet 😂 But can anyone agree that this is correct? Thanks guys!

98Z5V Posted March 7, 2021 Report Share Posted March 7, 2021 (edited) That's correct. Anything that will fit a DPMS LR-308 or the SR-25 will work. Armalite B-model magazines will not work. Oh, you don't have an AR-10, either. Only Armalite makes those, and nobody else, and there ARE design differences between AR-10s, and any of the DPMS and RRA patterned rifles.

Chip_Baker Posted March 9, 2021 Author Report Share Posted March 9, 2021 Wow. I did not know there was a difference. Thanks for the info. Interesting that all the .308 caliber ar platforms that are listed use that distinction. Ar-15 for the 5.56 and ar10 for the .308. Is it just a pattern all the sellers fell into or are there similar differences between them? Similar differences? 😂😂 I think you get my question 🙈 Thanks for the info👍 Quote Link to comment Share on other sites More sharing options...
