This is the receiver flat everybody has been wanting.  Made from 1.5mm thick 4130 to be used with modified 1mm parts kits.

The top rails are already bent and machined.  Due to the thickness there is no step down in the top rail or axis pin dimples.

Machining of the front and rear trunnions as well as trimming the stock/handguard to fit will be needed.  To make these work you will need to machine .021" off of each side of the front and rear trunnions.  The slot for the top rail of the receiver will need to be opened up slightly for the receiver to lock into it also.

Be sure to get the 1.5mm center support and use the flat bending die set with the 1.5mm punch.  If you try and use the 1mm punch and the thicker flat you won't be in a good mood after you see what happens. 

  • Receiver flat thickness= 1.5mm (.06") 
  • Material 4130 Annealed
  • Comes with bolt guide rails
  • Rails and flat need to be heat treated after bending


Reccomended rivets and center support (not included with flat)

  • AKM Fixed Stock Rivet Set
  • 1.5mm Center Support

 

To use these flats you will need to have a 5mm and 7mm reamer.  The physics of bending sheet metal make it next to impossible to have a bend close to a hole without distorting.  To solve this the holes on the flat are undersized and need to be reamed to size after bending.  Look at the receiver flat instruction page to see more info.

The rails that will come with the flats are pictured below. They have mag stabilizers on both rails to keep the mag from tilting and causing feed problems.  Before installing the rails you will need to trim the mag stabilizers to match the caliber of flat you are using.
