I have 2 mags, dont know what brand, got them as part of a package deal, I dont know if they work, i dont have an AR yet, but i need the money to buy my parts. So first one with $33 paypal to firstname.lastname@example.org or USPS money order gets them. I have no garuantee on these mags, but at this price, why not try!!
They are in excellent condition, strong springs, 90-95% finish.
Thanks for looking!
EDIT: yes they are 30 rounders
EDIT:I will make even trade for 1 NIW USGI
