So I bought a impulse hog hunter off of gunbroker. I really only want the action. I'm gonna turn it into a 22 creed thermal gun. I found out that the "Hog hunter" version uses some proprietary mag and doesn't use AICS pattern like the impulse predator. Are ya kidding me? What "hog hunter" wants a 4 round mag? Anyway, my question is this: can you get "impulse predator" bottom metal? Or what should I do?
