Im looking for some help regarding market values on the somewhat rare SIG AMT / 510-4 magazines
Its my understanding that SIG made the magazines in 3 capacities ( 5 round , 10 round , 20 round ) .
These are the steel / angular magazines made for the specific gun. ( Im not interested in the aluminum banana magazines made for the PE 57 )
Can anyone give me an idea of the fair market values on these magazines ( I ask because I have some to sell , and OI don't really know what they are worth now )
5 round mags / 10 round mags / 20 round mags ????????
value of each ( I believe that the smaller mags are more rare and pricy ? )
thanks for any help
