L3 ARS (Articulating Rail System) for the m240. Flips secondary sighting system (thermal/night vision optic) to the side for reloading without need to detach. Extremely rare. Original L3/Larue joint contract production unit for the USMC. Not a repro.

Everything ships within 24-48 business hrs of payment with tracking, well packaged and fully insured on my dime for full refund in the event of damage, loss, theft etc. If shipping insurance denies a claim, I make you whole and eat the loss. Zero hassle transaction. Local pickup in D(M)V
