Worthwhile February 21, 2016 : Kerry L   I completed a pistol build using this barrel and I was very impressed with the quality considering the price. The finish on the barrel is good, rifling is well defined and deep (looks like button rifling and not chemical etch). After sighting in my pistol, I was able to shoot 3" groups offhand at 12 yds. I was very happy. Make sure to clean the bore of this barrel before shooting as mine arrive very dirty (more dirty than any other barrel I have bought). Good barrel for the price and I would definitely recommend it. Was this review helpful to you?

Great little barrel July 13, 2015 : Jeff W   This barrel really shortened my 9mm SBR. I wanted something that I could go around corners and not lead with a 7.9" suppressor. Shot it at the range and got some good groupings at 25 yards. The shorter barrel and a suppressor does produce more gas in the face when used with the slick side upper also on MAS Defense but overall a great low cost setup. Was this review helpful to you?

5.5" 9mm Barrel April 19, 2015 : Bruce W   I recently purchased 2 of these barrels for pistol builds out of my shop. Fit and finish on both were perfect! Additionally, both have proven to be very accurate...100 yard steel targets are no problem! Bullets stabilize perfectly!Thanks!! Was this review helpful to you?
