Do the Sterling 40 rounders say AR15/AR180 on them?  If not, which brand does?

Thanks,

Which ones say "AR-15/AR180" on them then?

None I have seen say AR15/AR180.  Only indication is the cutout for both mag retainers.  Mine are all marked as Troy indicates.

Ditto!

Cheveytuff19 I would venture to say that the 40rd mag you described is a USA mag.  When USA did mark the floorplates of their mags it was usually with the rifle model number, example "AR15 223 or 5.56" on a 30rd mag.  This marking might lead the less experienced to believe that the mag was a USGI contract mag.  I had a 40rd mag that was sold to me as being a PMI mag, the USA mag wouldn't even fit in the mag well let alone feed or function, a piece of junk as most of the USA mags are.  The only reliable 40rd mags for the AR15 and AR18/AR180 are the Sterling and PMI mags.  Both fit and function in my AR180 rifles without a hitch.

The STERLINGS have the sterling/england floor plate and while expensive, are the finest 40rd mags ever produced to fit both the AR-15 and AR-180 series rifles. The "PRIDE" of the IRA !
