DoubleStar AK Stamped Internal Receiver Block

The ACE Internal Receiver Block requires permanent modification to the receiver prior to installation.  To install, remove the tang on the back of the receiver and file or grind smooth.  The internal receiver block will then simply bolt into the receiver.  The pistol grip T nut will hold the front of the receiver block securely in place. There is no movement to the receiver block once installed.
