I ordered a preban upper w/phanton hider & 3 rail gas block, M4, and got it in less than a week. I sent my preban lower in to have a 6 pos. telestock installed and it will arrive in less than a week and a half. I own 3 Bushmasters, AK Shorty,V-Match Carbine,& Preban M4gery. All are super accurate & function great. Thanks Bushmaster for a fine product and VG customer service.
