Anyone have an M&P 15/22

[Rapier]

Just wondering does anyone on the boards have a S & W M&P 15/22? If so how well does it really shoot and what have you done to trick it out?

I understand it is a family answer to every member's 22 rifle in the family and the Magpul version is very, very similar to the military rifle and can be used by a GI for practice. As a matter of fact, the M&P 15/22 is being sold by the local military and police dealer here bouts on the discount plan offered to M&P members.
