We custom-designed this O-ring-style rod guide specifically for the SCAR 16S, the semi-auto 5.56×45-chambered civilian version of the FN’s Special Operations Forces Combat Assault Rifle. It uses a fixed rectangular Delrin bolt collar designed to fit inside the SCAR action, with an aluminum tube and a machined Delrin solvent port. A must-have item for cleaning your SCAR quickly, thoroughly, and without risk of damaging the breech or chamber. Mfg: Sinclair International
