Personal opinion..... GM will probably put a lot of small barrel makers out of business. Those who's sole income comes from barrels will likely have no choice but go part time in the next 5 years. I think Rice told me that it takes him 105 minutes to swamp a barrel and that doesn't include drilling and rifling. I think he averages about 5 barrels a day.
Just think GM as Wal-Mart and everyone else as Mom&Pop stores. GM sells a barrel of the same quality and $50 less.... the others can compete. Slow but surely

Poke,
I doubt that will happen.
For the "$50 less" (actually about $35), of Green Mountain swamps, you will also have to buy a breechplug, buy a bottoming tap to finish cutting the threads, and spend a couple of hours fitting the breechplug . Then you also will have to be satisfied with their standard rifling twist and square grooved rifling.
Don't get me wrong, the GM's are a good product, and well made, if you have a well set up shop to breech them. I am building one now.
In contrast, with a custom maker like Rice, They come perfectly breeched, and you can specify any twist, caliber, round or square groove rifling, plus the barrels are heat treated (normalized) to eliminate any stresses, and a carbide ball pushed through the bore to make the bore perfectly true. The outside and inside finish of the Rice barrels are the slickest I have ever seen. Truly "custom made".
There will always be a clientel that will pay more for a "Cadillac" than a "Volkswagon", even though each will get you where you need to go.
Kind of like the difference between a Stelling and a Deering banjo, there will always be a market.
