Bulgarian Sidefolder AK74SU 5.45 Flat

$49.95

This flat was made for the Bulgarian style sidefolding triangle or polymer stock.  The magwell and magwell dimples are made to fit 5.45 magazines.  If you are going to use a 7.62 front end then look up my Khyber Pass receiver flat.

 

  • Receiver flat thickness= 1mm (.040") 
  • 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)

  • AKS underfolder rivets
  • 1mm 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.
