So, what's the verdict on these things? There's a bunch of them out there. Which ones work well? Which work well with bulk ammo (Fed/Remington/etc.)? I don't see the need to get something that needs premium fuel. Which are to be avoided? Conversion top halves a better value? Which of those work well? They are peaking my interests a little bit but mostly my dad's pretty excited about something like this. I didn't have a chance to check out any of these at SHOT. Off topic a bit, but a similar question would be does anyone have any experience with any Glock conversions? I have the same questions about those. Thanks. Wanna kill these ads? We can help!
