THESE DO NOT HAVE ALIGNMENT HOLES IN THEM ANYMORE
The AMMS trunnions I have seen are machined unlike the Polish which are stamped and welded together. This flat will not work with the Yugo M70, Yugo M92, Polish Underfolder or Romanian Underfolder rear trunnion.
- 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 Rivet Set
- 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.
This item is made in the United States and counts as a 922r compliant part.
