(PICTURED WITH SLR SOLO LITE FOREARM)
10.5" 6.8 SPC SBR/Pistol Upper - YHM Forearm
Important Forearm Note: If you are using your own muzzle device, including brake, flash hider, or silencer, please let us know (in the comments section of your order at checkout) what you plan to install so that we can double check compatibility with the forearm you have chosen. We will get the best fitting forearm for your intended use, and we will contact you to discuss options if needed.
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 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 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 SPC upper is built around one of our 10.5" Pistol profile 416 stainless steel barrels, which features 4-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 AR-15 barrels, click HERE.
