The ARCA Flex is the ARCA Rail turned sideways. This NEW product was introduced at SHOT SHOW 2025. It is designed to be mounted under the action of the rifle where the balance point is. It is narrower and more comfortable to carry than traditional sideways mounted ARCA. It gives you flexibility and ease of use that you need for mounting your rifle. This rail system is commonly used for mounting ARCA style tripods making it easy to mount and comfortable to carry. Now the ARCA Flex system is your all in one solution to mounting your rifle with smooth rounded edges for a comfortable grip holding your gun. Available for M-LOK rail system and screws for more traditional style rifles with synthetic or wooden stocks.
