14.5-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 components selected from respected brands and industry friends and partners at a variety of price and feature levels. All 14.5” Riflespeed 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. A detailed data sheet with product information including gas port size is included with each upper.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.
