Trying to get the background information on theses mags / I have 35 of them they are stamped BRW S-I
Borg Warner(BRW SI) Mags can be marked Upside Down or even Sideways, without it being a Fake, If it is marked BRW S1 instead of BRW SI, It's a Fake (CMI Body) and will still work, marked to make one think It's a 60s GI Mag.
I bought 5 new CMI's in November, took 2 of them to the range and neither one did a very good job of holding the bolt back on last round, or, the bolt would slam shut on removal. It seems like an issue that's been done to death on this forum with no straight up answer from the folks selling them, some here have complained of having the same issue as me, or mags not fitting properly, or having to take a Dremel and tweak them to work.Though not OG, CMI is good stuff.
