16” Recon 6.8 BSP Upper Assembly with Basic Forearm
Base Components: The base upper includes the following components, all of which we will assemble for you before shipping: upper receiver with port door and forward assist, bare stainless barrel, low profile gas block, gas tube, forearm and Stag 6.8 bolt. If you want something ready to shoot right out of the box (assuming you have a lower assembly ready to go), you will need to add a bolt carrier, charging handle, and muzzle device.
Bolt Options: This upper assembly comes standard with a Stag 6.8 SPC bolt (black phosphate). If you select a different bolt from the “Bolt Options”, your build will be upgraded accordingly. We check every bolt / barrel for proper headspace before they leave our shop. For more information on the bolts we stock, click HERE.
Bolt Carrier Options: If you choose to purchase a bolt carrier along with your upper, it will be assembled for you and include the gas key and firing, retaining and cam pins. For more information on the bolt carriers we stock, click HERE.
Barrel Info: This 6.8 upper is built around one of our BSP (Subsonic) Recon profile 416 stainless steel barrels, which features the SPC II chamber, 6-groove / 1:7” twist button rifling, a 5/8-24 thread muzzle, carbine length gas system and M4 feed ramps. Each barrel is hand fitted to the upper receiver during assembly to ensure smooth cycling. For more information on Bison Armory subsonic AR-15 barrels and ammunition, click HERE.
Forearm Info: We currently offer Yankee Hill and White Oak basic free float forearms. These forearms do not have picatinny rails, and limited (or no) attachment points for accessories such as sling-swivels and bi-pods. We also offer carbon fiber PRI Gen III Target forearms. Although simple in appearance, these forearms deliver peak technology and performance. Mid length forearms are 9” long and leave the gas block exposed when used with a mid gas barrel. Rifle length forearms are usually 12” long and cover the gas block when used with a mid gas barrel, requiring the use of a low profile gas block. For more information on the AR-15 free float forearms we stock, click HERE.
