M193 .223 is thin copper jacket over lead bullet, and is going so fast that it will punch right through regular carbon steel (within a couple hundred yards anyway) The hoses are even more susceptible.
And that is presuming an AR-15 round. Only reports I have seen regarding the gun call it a "AR style rifle." That could include the more powerful AR-10.
