Notes regarding 10 round AR style Shotgun Magazines & Compatibility with other AR style shotguns: 

Generally these type of shotgun 10 round magazines may require a break in period. Also they may require slight modification to work other shotguns like the MKA 1919, BR-99 and FR-99.

These magazines should work with other MKA 1919, BR-99, and FR-99 shotguns (we have not tested these magazines for fit in these shotguns, however we know that FR-99 BR-99 and some MKA 1919 shotguns work with Panzer AR12’s).  As we get more information on which shotguns these factory new Panzer Arms AR-12 & BP-12 10 Round Magazines work with, we will post it here:
