Must be a Genuine Colt buttstock. I don't care what the battery compartment holds (DL 123 or AA)or if it is the model without one. They look like the old ACR buttstock NOT the civilian Rock River looking one with the steel sling swivel. The tube would be nice but not necessary. The commando 2 piece buffer or #2 or #3 buffers as well.
I helped rezero and fired a couple 5th group SF guns on Thursday at the range and would like a stock for my privately owned M4A1. Thanks in advance on any leads. V
