Polymer 30 round magazine by SGM tactical, Made in USA.
Fits .223 Saiga, locks up snug, no wobbles.
Ive only used it a few times and its run flawlessly - Locks the bolt back on the last shot to let you know youve run dry - though bolt is released when magazine is removed.
Selling as its not seeing much use lately.
For use in an E-category semi-auto or straight-pull rifle.
