These are a set of 4 Alexander Arms marked 6.5 Grendel steel magazines made by E-Lander in Israel for Alexander Arms. The short mags are 17rd mags, and the 30rd style are 24 round mags according to Alexander arms. Only the one 17 round mag out of the package has actually seen any use. The others are NIB or ANIB. For the set of 4 these cost right at $80 plus shipping. Asking $60 FTF in the Jackson area or will ship on your dime. Not interested in trades, and would prefer to sell as a lot at this time.
