Guntec usa ar-15 pistol length gas tube - Guntec USA AR-15 Pistol Length Gas Tube

The gas tube had perfect fit and finish and installed very easily. My only concern is that it did not come with the roll pin needed to attach it the the gas block. I happend to have an extra pin at the ready but this could be very frustrating for someone who didn't. Other than the lack of the roll pin it is a great product.
