CMMG 22Lr Upper.

[Fantomas]

Are you carri the Sierra .22 LR Upper Receiver w/Low Profile FSB?

[Riflegear]

Sierra? We carry the .22LR M4 type upper. I'm not sure what you mean by Low Profile FSB. It comes with a regular F-marked front sight base but it is not "lo-pro".

Ahh yes. No we don't have that one. We do however have the M4 Evolution in stock.
