Been putting this together for a couple months now. I came across a damn fine deal on a new LMT MRP rifle length upper and thought I would make it into a proper rifle since I already had 4 carbines. I was waiting for some LMT lowers with the A2 stocks to come back in stock somewhere but decided to just get a standard lower and add my own. She wears a TA31F on Larue and a set of KAC BUIS. I will add a 18 inch SS barrel in the future as well as a better trigger. for now it is good enough to shoot which I have yet to do. I really like this set up.
