Author: Trevor D.

A: Eugene, seems to work just fine Sir in this review : https://www.thetruthaboutguns.com/gear-review-magpul-pmag-40-gen-m3/
Author: James G.
Q: just wondering if this magazine was universal
Author: Kevin T.
(3) ANSWERS
A: Hi, This magazine will pretty much work on all AR15 in 5.56. That being said, ProMag (The maker of Rollermag) has mixed reputation for quality of their magazine. I recommend looking at other option such as magpul instead. I hope this helps.
Author: Trin K.
A: Kevin, yes Sir it is universal. Since it is a ProMag, it may be hit or miss with reliability. The Magpul 40rd is surely a hit when it comes to reliability (out of stock at Buds currently): https://www.budsgunshop.com/product_info.php/products_id/714007715/magpul+pmag+m3+223rem+40rd+blk -------------- But can be found here : https://gun.deals/search/apachesolr_search/873750009698
Author: James G.
A: Kevin, Yes this magazine fits all AR 15 platforms, but stay clear of these.
