all the unicorns and cast vs forged debate aside......
It's pretty difficult to get an M1A receiver unless you find one in the EE or happen across someone parting out their rifle.
the last one I saw listed here was listed for 900 (?) iirc
Chinese receivers I've seen go for 150 to 250.00 , higher end for the rarer unmarked or early heel stamped polytech versions.
if I was willing to drop 900.00 for a semi auto only m14 type receiver...... I 'would' absolutely look to a forged unit and pay a few hundred more for an LRB M14SA , and if my end game was to have a scoped m14 type rifle , no need for the extra scope mount when there is an LRB M25
not sure if JRA is selling receivers only and not sure if there are any Smith Enterprise receivers coming up this way.....
Prophet River, irunguns and Armtac would be the three places I would start my quest to have a non Chinese receiver imported.
an add in the EE might get you somewhere as well.
