Epps last time I checked. they're expensive.
I have a 20 gauge that will be with me until,death does us part. LOL
had a 12 gauge that when you put the base screws on, they would bulge in the rifling inside the barrel. when I contacted T/C , they said it was unsafe and a known issue with some of the 12 gauge barrels. the 20 gauge stainless was the warranty replacement and I love it. I still have the base and forearm for a 12 gauge barrel. I plan on try another some day, just have a hard time spending 600$ + on one........
