The Sons of Liberty Gun Works 12.5" Precision SPR Barrel Chambered in 6mm MAX is a match-grade rifle component built for short-barreled precision applications.

It is finished with a durable black oxide coating and uses a carbine-length gas system specifically tuned for the pressure requirements of the 6mm MAX cartridge.
