www.warpig.com reviewed the Tribal Stix barrels.  Their conclusion was “Operationally the Tribal Stix barrel performed as one would expect a well honed, ported barrel to perform. It’s light weight conveniently was not a burden when carried on the test marker (Matrix LCD.)”  We think its an incredible value at the $39.99 price range.  You can read the whole WARPIG Tribal Stix review here.
