Just placed the order for my second M4. This one's model 11722. Gonna be a while before I have it in hand but my BoTach C-stock can now rest a little easier knowing it will have a home.
Looks like about a three month wait on the gun. Then another 4-6 weeks for the transfer to my class III ffl. Then another 4-6 month wait for all the federal paperwork. Maybe I'll have it by next Christmas. DOH!!!
