AK-Builder 80% Prebent US Polish Underfolder Receiver Blank

AK-Builder Hungarian Underfolder Non FFL Prebent US Receiver Blank

$59.95

NEW Hungarian Underfolder PKMS Bent Receiver Blanks - 80% Complete

Just like our Hungarian Underfolder 7.62 receiver flat, without the fire control group holes these are bent and ready to go. Simply weld in your bolt guide rails, drill and install the center support, use our V4 driling fixture to drill the fire control group holes and heat treat.  Made here in house and counts as a 922R part. The top rails are already bent, embossed, and machined unlike the Polish 80% blanks. We offer this item as the shell itself and as a kit which will include the bolt guide rails and center support rivet with tube. Includes the Y and I stamping for a more authentic look!

THESE ARE NOT HEAT TREATED

Made from 4130 Annealed Steel.

This item is made in the United States and counts as a 922r compliant part.
