I have a CMMG Quebec dedicated .22 AR with all the fixings. It was expensive but I came to the conclusion that if you want a .22 last looks feels and shoots like a 5.56 and is made of metal and not plastic, its going to be expensive. It is setup just like my sig, even has an Aimpoint 3x mag and Patrol Optic. I love it, can't hardly tell them apart. Very accurate and I have had not had any problems with any types of ammo. I don't know if they sell them any more though, last time I checked their site they weren't listed. Nothing like going to the range and shooting 500 rounds and it only cost $20.
