The only negative I have on this is that the gripframe is not as easy to install as standard AR-style grips due to the solid base of this unit. If there was a hole drilled in the bottom that would allow a long hex wrench to access the screw it would be perfect.
Otherwise, this is a great grip. If you don't like 1911's, you might not like this grip.
Pros: Brings 1911 ergonomics to the AR platform
Cons: Harder to install due to solid base
