In true enthusiast fashion, I bought the Alpha 10" rail and Alpha stock before buying the host. I'm waiting on the Alpha railed top cover to return to stock.  A few questions:

1) Does anyone know whether the VSKA 7.62x39 can accept the alpha railed top cover? I cannot find the rear trunion size of that gun. I have outreach pending with CAI.

2) I am pretty sure the 10" rail should fit with modification. Does anyone know?

3) Does MI have an idea when the top covers will be back in stock?

thanks.
