This video features a range test of the PTR 91F, a rifle described as a heavy-barreled clone of the HK-91, which is the civilian version of the G3 battle rifle. The reviewer highlights its reliability, attributing it to a fluted chamber and delayed roller blowback operation. They also discuss a minor issue with brass ejection and mention aftermarket port buffers as a solution. The trigger's 7.5lb pull weight is noted as not ideal for precision but still allows for surprising accuracy.
