LWRC ICPSD Upper Features The LWRC ICPSD upper is built around an 8 inch centerfire barrel chambered in 5.56 giving shooters a short maneuverable platform without giving up the reliability LWRC uppers are known for. The ICPSD series is engineered specifically around integrally suppressed and compact SBR style configurations so the barrel length and gas system are matched to work well with a suppressor mounted on the threaded muzzle. That threading also accepts standard muzzle devices for shooters who prefer a brake or flash hider instead. A shorter barrel like this trims overall length for vehicle work close quarters engagements and easier maneuvering indoors. Finished in OD Green the upper gives a distinct visual break from standard black builds while standing up to the same hard use LWRC s coatings are designed for. The complete upper bolts onto any mil spec AR-15 lower making it a straightforward way to add a second configuration to an existing rifle. Builders can swap between a duty length upper and this compact ICPSD unit without touching the rest of the rifle. This upper is for sale at GrabAGun for shooters assembling a dedicated short barreled 5.56 build.
