I';ve also had good experience w/ Bushmaster. Total turn around (out of my door and back to my door) was 5 days. Pretty fast; oh, they also picked up shipping costs.Chris wrote: i sent my M4 to bushmaster for a canted front sight block. took 3 days to get there. they kept it 1 day and shipped it back the next day. it had a new barrel installed and was dead on accurate.
Edit to add: Bushmaster also test fired my rifle too.
