Riflespeed complete upper receivers are an ideal solution for anyone without the time, tools, or inclination to build an upper. Choose from a number of high-quality components selected from respected brands and industry friends and partners at a variety of price and feature levels. All Riflespeed 300 AAC BLACKOUT uppers include a Riflespeed Gas Control and Riflespeed Gas Tube. Your Gas Control will be installed for tactical use by milling the barrel and cross-pinning the Gas Control Body. This creates the most professional duty grade installation possible with no chance of loosening set screws or slippage of the Gas Control causing malfunctions. Each upper will be test fired to verify performance with subsonic (suppressed) and supersonic (suppressed/unsuppressed) ammunition.
Use of a Riflespeed Gas Control on a 300BLK upper creates opportunities that have not previously existed on a practical level. Specifically, you can dial down to setting #1 to limit gas so the bolt never unlocks when shooting subsonic ammunition. this allows you to have a manually operated AR that is bolt-action quiet. Next, simply dial up to a higher setting that's appropriate for your subsonic ammunition (#10 with Hornady Black 208gr, for example) and your AR will cycle subsonic ammo normally again. All of this can be done in seconds with NO TOOLS required.
Select the Master Blaster package for your assembled upper and we'll test fire for accuracy, determine the proper Gas Control settings for multiple types of ammo, and deliver a full performance report with accuracy targets and a settings chart with ammunition types.
The following configurations are currently available. Each upper will be assembled, inspected, and test fired to verify function with Milspec ammunition upon order. Expect shipment within 5 business days. Add 3-4 days for Master Blaster upgrades. Note that muzzle devices may be pictured in some photos above, but you'll receive an upper without a muzzle device. This reduces cost to you and allows easy installation of whatever suppressor mount you prefer to use.
