1000 rounds down and plenty more to go

Functions well it may have lite striked a few primers or it was just the supper cheap steel case ammo (the world may never know). Brass case ran perfectly the whole time. It is extremally light leading to a little less recoil. All around I'm happy with it but it is a little pricy.
Needs enhanced firing pin for 7.62x39 which it doesn't come with

I wrote a review on this the other day but apparently it didn't get posted. So I'll try again. This bcg is very overpriced for the simple fact it doesn't use the right length firing pin that 7.62x39 requires to function reliably . I swapped the firing pin to an enhanced firing pin and it works flawlessly now but just a shame it's not ready to run out the box even though it says it's supposed to be.
