So far I have done three builds... My first were using OOW receivers that were already heat treated. The last is a Tapco Flat that we needed to heat treat...
We heat threated my flat using the following basic steps...
1. heat all areas of receiver that has holes for pins or rivets as well as the ejector rail tip with a MAPP torch until bright red.
2. Quench the Receiver in motor oil
(Note do above one or two holes at a time)
3. Reheat receiver parts as described above to a dull red.
4. Allow receiver to cool at room temperature.
Note: When using the MAPP torch I was warned to use a broad flame when heating as opposed to one of the cutting type heads! Also, this was an AK pistol that I really don't shoot much so while I have not had problems it needs to be said that I may only have 100-200 rounds through the gun!
