Selling a pair of AR15/M16 .22LR drop in conversion units.
Remove your bolt carrier group, replace with conversion unit, and you're ready to fire .22lr
Both units in excellent lightly used shape.
Neither is marked as to mfg (these drop in units never are), based on comparisons w/ google images I believe they are probably CMMG, but there is no way to know for sure.
One was marketed by Brownells and comes in a plastic tube with instructions, the other is just the unit.
$100/ea FTF in Henrietta NY
Happy to ship in buyer's dime.
