Many feel there are advantages to the billet method of production which is essentially machining a block of alloy from scratch and dimensional inconsistencies can be avoided which sometimes occur with the forging method, in which the receiver is hammered into shape while heated.

Rainier Arms currently has the billet lower available for $175.00
