Ironwood DesignsThe weld is along the tang side. The other three sides are just pressed in. Use a reinforced cutting wheel on the dremel to make a cut just under the tang. You should see the edge of the plate. Cut the plate, being careful not to cut the reciever. Go slow and you'll be ok. After the plate is out, use a grinding stone on the dremel to smooth the weld area flat, and you're done.
If you're lucky like I was, you'll have a standard rear trunion. The only problem is that the MAADI reciever is slant cut ...it's about 1/4 inch shorter on the bottom of the reciever, than at the top. Regular stock sets will not fit properly. The only ones I've found so far are Ironwood and MSG manufacturing. I spoke to Matt at Ironwood about three weeks ago and he stated that they had no AK 47 stocks in stock and they would be doing a run of them in a few weeks. I left an E-mail message and am waiting for a reply stating the stocks are ready.
MSG was advertised in Shotgun News and offers a black polymer stock set (butt, upper and lower handguard, and pistol grip) to fit the MAK 90/MAADI slant cut recievers for 39.95 plus shipping. I called them two days ago and spoke with a guy who stated that the stock sets are reverse engineered. I am contempalting the black polymer stock set.
Hope this helps you.
