Having been over and over this and many other forums I am still not sure of the question of
“what magazines work with what guns”
I have a 2012 Bushmaster 308 OCR , besides bushmaster magazines what other types Can I use
Can I use M1A mags? , Can I use fnfal mags? Can I use thermold usa mags?
Besides that I would like to ask which type of Mag work better that others…
How would you rate the reliability Mags by manufacturer
Current Bushmaster 308s are DPMS and take the same mags (308 PMags are the most popular).
There are three main styles of magazines in the .308 AR’s, and a mythical 4th.
From Most prevalent to least:
Original AR10 style mags (including KAC mags, and PMAG-LR)
KAC
LMT
Larue
DPMS
LWRCI
Sig 716
2013 Armalite
2013 Bushy
2013 S&W
Eagle Arms/Armalite AR-10 a modified M1A style mag
Pre 2013 ‘new’ Armalite AR-10
Noveske N6
Hk417 mags
Hk417
MR308
FN FAL Metric Mags
~2006 Bushmaster – not sure if any actually shipped other than SHOT demo models
Realistically the 7.62 AR standard mag is the KAC Mag based on the original Gene Stoner AR10 magwell.
With over 17,500 SR-25 style guns (M110/Mk11/M110K1) shipper to US and Allied government - and at least 10 mags for each gun sold - its pretty much been solidified by the introduction of the PMAG-LR by Magpul.
