No Shipping at this time. Local meet up in the SF Bay Area preferably on the Peninsula.
Other info: The Bushmaster BCG is NOT included with this upper. The Bushmaster XM15 Charging Handle is included. I am the original owner of the upper which is in good overall condition. Shows some minor signs of use and has around 600 rounds through it. I had added a Daniel Defense 12.0 FSP Lite Rail II and a Lantec Dragon Muzzle Break, both which have been removed and the upper has been returned back to stock condition.
