I recently purchased a SKS drum magazine.
I shot it yesterday for the first time.
All the crap you hear about them not working is poop.
My 30 rd mags suck cheese, however this 75 rd. Chinese manuf. Drum is my new best friend.
Great feed and smooth as my AK drum mag.
The magazine catch needed to be "persuaded/bent" a bit to latch properly onto the rifle but it functions well now.

the pics are from my phone..srry about quality.
But yes it is for sale..
