Work of art... I thought I would be disappointed because I really thought I wanted a phosphate finished barrel. BUT I was also on a budget and this was a great year end deal. It is beautiful....

Great product
July 28, 2015
: Donald K
Barrel arrived quickly, was packaged properly and is of excellent quality. I used to build a QC10 9mm pistol build. I highly recommend this product as a prior USMC armorer and current LEO/Firearmsinstructor.
