Lightweight AR-15 Barrels Are Not Accurate When Hot? Test. (HD)
This test evaluates the accuracy of lightweight AR-15 'pencil' barrels when heated. A Faxon 16-inch pencil barrel rifle was tested, showing a cold group of 0.75 inches and a hot group of 1.75 inches after rapid firing. While accuracy degrades, the dispersion remained acceptable for practical uses like home defense or hunting.
