    Very nice lightweight barrel. It assembled very easily and appears to be fairly accurate. I have only fired 50 rounds or so out to 100 meters using iron sights and a 3 MOA red dot. My last 5 shots at 100 using iron sights measured 2.5″.
    Shipping was very quick one I ordered it online.

    Great service, great product! Had my local gunsmith target crown this barrel. He has been working on guns a long time. He said the barrel had one of the nicest bores he had ever seen, and it should be a great shooter! Installed it on a Aero Precision COP monolithic upper,PSA chrome 6.8 BCG,DD flash suppressor! Topped it off with a Nikon pro staff 4×12 scope, stuck it on a lower with a standard stock trigger. Put about 70 rounds through it, had one three shot group shot at 100 yards that could be covered with a dime!! Very impressed, makes ordinary shooters look like marksmen! Lol
