The Battle Arms mil-spec 6-position buffer tube in OD green is a carbine-length receiver extension for AR-pattern rifles, finished in OD green anodizing (brand part no. AR15RE-MIL-6C-ODG). Battle Arms Development machines it in the USA from 7075-T6 aircraft-grade aluminum and gives it six stock positions. It is sold as the tube only, so the buffer, buffer spring, castle nut and end plate have to be bought separately. The builder who is assembling a lower from individual parts, or replacing a damaged tube with a color-matched one, is the buyer it is made for.

• The tube is precision CNC machined from 7075-T6 aircraft-grade aluminum, a strong, light alloy.
• The finish is Type III hard anodizing in OD green, a tough coating that resists wear.

• The listing is for the tube only; the buffer, buffer spring, castle nut and end plate are not included.
