    Build #2

    I chose Shooters Gate to try my second AR-15:Pistol build. This kit was matched with a reputable lower receiver and it went together perfectly so far! Took the new 10.5 pistol build to the range yesterday and the gun ran flawlessly! Very satisfied and I will be a repeat costumer!!!
