12.5-Inch Assembled Uppers

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 options selected from respected brands and industry friends and partners at a variety of price and feature levels. All 12.5” Riflespeed 5.56x45mm uppers include an RS7543 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 and Plunger selection.
