Hell if its about saving money, do what I did. I bought a Bushy lower...saved some money bought a bushy barrel....saved some money bought the rest of the gun RRA upper reciever had it put together the way "I WANTED IT" saved me 300 bucks doing it this way. I have had zero problems with it. And I also just bought a trijicon Acog TA31F scope (*badass*). It might be worth checking into, doing it yourself that is. And colt is very over priced especialy if you want an LEO gun if you go that direction get the 6920 version. And they hold their resale value very well.
