Chassis

I have an MPA Competition chassis for my Impact action. Really nice setup, and easy to find deals on the PX for them. Having said that, I'm looking at the MDT ACC chassis; more modular, with greater ability for adding/adjusting weight. It also has a longer foreend, which eliminates the need for a spigot mount.

For reference, with the full weight kit, 26'' M24 barrel and my Razor 4.5-27, my MPA weighs right around 23 lbs.

However, once properly configured, there is practically no difference, just a preference for one over the other. MPA might by slightly cheaper, but can't go wrong with either.
