I am putting together a group buy on uzitalk.com for Vector 68-round drums for full and semi-auto uzis. Here is how Vector describes them on its website:
68 rd. drum mag. For UZI 9mm. Works with full size and mini open bolt. Comes with winding tool to keep your fingers out of harm's way. Spring release button has a new, added safety feature to prevent accidental release while loading.
Regular price: $295 plus shipping.
Group buy price: $255 shipped.
If interested, please check out the thread in the "UZI Talk" section of the uzitalk.com forums for ordering/payment/shipping details. Thanks.
