The MD arms one.

I converted it. I buy all of my parts from Carolina Shooters supply he really has good customer service and the shipping is fast. There is a discount coupon for his site (5&#37 too.

I have done the following:
  • MD Arms Molot Style grip
  • Adjustable Polychoke II with the breacher tip
  • Vltor M4 Style aluminum tube milspec size
  • MD Arms V-Plug adjustable gas knob
  • Conversion kit from Carolina with Carolina SS trigger guard.
  • Magpul forearm grip
  • Tromix charging handle
  • Polishing work on the bolt and some on the hammer
I am sure there is more that I forgot.

I have read that some people say to stay away from the promag drums but I don't have any experience with them.

I would definitely do some reading over on the Saiga12 forums. I learned a lot over there.
