I believe the SR15 Match uses a stainless steel Krieger barrel; but whoever makes it, it can shoot.
Maybe coldblue will weigh in on barrel and materials.

I'm well aware of the barrel on the SR-15 Match, however, you questioned my post regarding the barrel on the SR-15 M4 - not the SR-15 Match.
I believe you'll find the barrel is chrome moly on the $1400 SR-15 M4. That is the same barrel used by ArmaLite on their AR-180B at $650. I say again, the SR-15 M4 is a nice package but at that price point ($1400) the barrel should be chrome lined.

Edited to add: I guess I should have stated that I presently own an SR-15 M4 and have owned the SR-15 Match as well as a couple or three SR-25's. I'm primarily an ArmaLite guy but do not close my mind to other good weapons.
