Don't want to build your own Riflespeed Gas Control-equipped upper? Let us build an upper for you. We offer this option for those without the time, tools, ability, or inclination do so on their own. Select from a number of high-quality components selected from industry friends and partners at a variety of price and feature levels. Build time varies according to parts availability. All 18-inch Riflespeed 5.56x45mm uppers include a rifle-length gas system and a model RS7533 Gas Control.
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. Your Gas Control will be installed
by applying high-temperature
thread locker to the set screws and drilling the barrel for the
cross-pin. This creates the most professional duty grade installation
possible.
