My Colts have never been anything but tough as nails and extremely accurate right out of the box.
And same as Flave, mine haven't failed ever. I put a real nice Leupold scope on the one recently, and it's hosted at least 3 other optics. Lots of rounds through it and NEVER burped. The other one currently wears an ACOG TA31F with a TA51 mount. Just emailed my gunnie on opinions for a new forend for that one this morning. Probably go MWI or Troy again.
Slaves get what they need. Free men get what they want.
