The “SC” line up from Red Right Hand.

“Suppressor Capable” uppers that come in at lower cost to Our Duty & GPR Series of “Suppressor Ready” Uppers.

We understand you may not need the capability to readily switch the gas the turn of a dial but need the ability to possibly adapt to a silencer here and there and master the role of becoming suppressed. These uppers where designed to be able to accept and be tuned for that use once it becomes available.

Enter the “SC” line up from Red Right Hand llc.

Using the proven and capable Aero Precision Adjustable gas block or the Superlative Arms Adjustable gas block at the heart of this upper, The End user can dial in their system and adapt to the silencer of choice when needed. Not a field swappable system, but a system, that can be geared to one role and dialed in for perfect function prior. These uppers bridge the gap between a standard mil-spec gas system and the excellent Riflespeed gas systems available on the Duty & GPR series. Coming at a more affordable cost to entry, and still built for hard-use, look no further than the SC series of Uppers from Red Right Hand.

These Uppers have the nice short dwell time perfect for a suppressor host. We offer a few quality muzzle devices to be pin and welded to make them legal 16″ Rifle uppers. The Griffin Armament Plan-A and Duel-Lock 2.25″ Flash hiders or the infamous SOLGW NOX Keymo Device. One may choose an option for “None” (Bare Muzzle) and buy their own device to be pin/welded by their local gunsmith. (ALL NFA RULES APPLY).
