I'm on the fence about buying a manners from a member here - I prefer a stock, but would really like the barricade system. I know Manners now offers on new stocks, but is there any way to get it in an existing manners?
Any competent smith could put it in. Really no difference than installing an Anchuntz rail. It takes cutting the channel, then reinforce the barrel channel with carbon fiber.
I have thought about replacing my Anchuntz rail with an MPA, but I've had an idea for another rail setup, we will see when I get some time to get rolling on it.
