Odin Works M-LOK to Arca Trax Rail Matte Finish Black. This rail system is commonly used for mounting Arca Swiss style tri-pods but it also can be used with Arca Swiss style bi-pods too making tri-pods and bi-pods easy to switch back and forth between. We've all been there having to take off a bi-pod mount and switch to a tri-pod mount at the most inconvenient time. Now the ARCA rail system is your all in one solution to mounting your rifle no hassles guaranteed. The ARCA TRAX allows for Arca Swiss quick release accessories to be seamlessly attached to your rifle. Depending on your needs you can order one TRAX or go with the 3-pack and make a seamless rail. Many shooters use the TRAX Rail so they can be mounted to an Arca Swiss tri-pod for stabilized shooting but many bi-pods have the Arca Swiss attachment style too. Switching between being tri-pod mounted to bi-pod mounted has never been easier. Extra cuts are made for mounting clearance weight reduction and to give the rails a styled look. The ARCA rail is compatible with any MLok rail and is machined from billet 6061 aluminum and is hard anodized. If you've been looking for the best tri-pod or bi-pod mounting system for your AR the search for both is over.
