Opinions vary. I discuss quality work and suppliers, not third tier.
There are several levels of acceptability when it comes to quality. Those with little expectation or lack the ability or experience to discern quality often will use price as a discriminator. There is nothing wrong with Shaw when the expectations match the lack of quality. If it works for you, great.
Not everyone is willing to buy a Bartlein barrel then pay a top of the line gunsmith to fit it and cut the chamber. That's why there are companies such as Shaw, they fill the niche for people who need to pay less and don't require the best.
