Shaw makes standard grade barrels.
The likes of which you will find on many factory produced rifles.
The barrels will likely be completely serviceable, but they are by-no-means "high quality"
High quality barrels are made with a high quality barrel blank, usually from a name brand barrel like a Shilen, Douglas, PacNor, Krieger, hart, Lija etc...

I specialize in "High Quality" barrels.
Make no mistake, my pricing is nowhere near a shaw barrel, but then thankfully, neither is my quality
If you just want a blaster, the shaw will be fine.
If you want something custom that you just can't get anywhere else, drop me a line...
