Had a Colt M4 OPS. It was OK, I guess, but I quickly sold it after purchasing the vastly superior CMMG Sierra .22lr upper for my AR-15.
The CMMG is built like real AR from steel and aluminum, not like a converted air soft rifle with ZAMAK innards and a fake barrel shroud over a skinny little pencil barrel like the Colt.
No comparison between the two.
CMMG also offers a complete .22lr AR rifle that will accept centerfire uppers.
A liittle more money, a lot more rifle.
