LWRC International IC-SPR 5.56 NATO Rifle - 16.1"

AR-15 Rifle


The IC SPR variant utilizes the same Cold Hammer Forged, spiral fluted barrel as the IC Enhanced. The SPR employs a low profile fixed gas block for the piston system and a longer 12 inch user-configurable, modular rail system. Topped with our low profile Skirmish Sights, the IC line of rifles is the latest evolution in the LWRCI 5.56 rifle.

The IC-SPR is our flagship and most popular model. This is a great all-around 5.56 rifle that utilizes LWRC’s most popular features; fluted barrel, ambi controls, and SPR modular rail system.
