The XCR I have just purchased has .223 stamped on the barrel, which I have heard is due to 5.56 x 45mm models not being allowed into Canada any more. The Model I have is a heavey barrell 18.6".
Recently I have been pondering the idea of obtaining some military 5.56 instead of regular .223 American Eagle, Winchester, etc.
Is is my understanding the 5.56 x 45mm NATO has a High Pressure than .223 rem.
Can you shoot 5.56 x 45mm with the higher pressure without damaging / causing problems??
