New kid on the block! These carriers have been hand selected and sourced by ROD to be used in our MOD S billet builds!

This carrier feature set is superior and complements our Slab Side Cut Down Vent gas carriers, which now will be used in our MOD G builds as standard and the Chrome Lined Phosphate carriers in our baseline builds!

17-4 SS Carrier
Gas Nitride External Finish
Proprietary Gas Pocket Design reduces right ear signature by up to 10.5dB on suppressed AR-15's
Proprietary NiB Gas Key with Physical Stop
Increased Cam Pin Travel Length for delayed bolt unlock (roller cam/delayed lovers unite!)
Carbon Scraper Geometry Cuts

These new carriers will be paired with our Dual Ejector C158 bolts and Sprinco springs and rings!
