Receiver Flats

AK-Builder Flat

The front of the receiver is trimmed out far enough to allow the trunnion to just slide in without trimming unlike the other flats that are on the market.  Theirs are stamped and need the flange to be a certain length to be bent.  My top rails are CNC machined to look like the original receivers.
