Guns Arson Machine Offset Light Mount Tom Marshall February 21, 2018 Join the Conversation Thanks to a bustling and innovative aftermarket, we’re blessed with myriad ways to mount all types of accessories to America’s Rifle. Not only do we love the ability to play “black gun building blocks” but many of these aftermarket companies are small shops owned and operated by Americans who are using their skill and genius to make a buck by making our lives a little more convenient. Arson Machine Co, based in Oregon, is one such company. They CNC-machine a whole line of specialty accessory mounts and muzzle devices for the AR platform, with the bulk of their products consisting of light mounts. We’ve been playing with one of their offset light mounts on and off for a little over a year. While most offset light mounts either bias the weaponlight further forward, or cant it 45 degrees, the Arson Machine take on this particular problem is to cant the light a full 90 degrees. The mount is available in both MLOK and KeyMod variations and is essentially a short piece of picatinny rail that, when mounted, runs parallel to the top rail of your handguard. We mounted it on a 12-inch MLOK tube from Barnes Precision Machine and tried a couple of different lights with it. Arson’s website says this mount was designed primarily for pistol lights, such as the SureFire X300 and Streamlight TLR-1. The X300 was the one weaponlight that seemed to provide the best overall fit and function, at least for a right handed shooter mounting this on the left side of their handguard. Next up was the Inforce WML. We had a little bit of trouble getting this light to fit as the Arson mount is designed to hold the light very tight to the rail. Also, with the mount being on the left side of our handguard, we could barely nudge the tightening wheel down as it was wedged tight against the handguard. Flipping the mount to the right side of the rail allowed us better access to said wheel. We were still able to actuate the WML’s big button by curling our support thumb over top of the handguard and hitting it. Your mileage may vary depending on the diameter of your handguard, and your hand. With the mount now on the right side of the gun, we mounted a Surefire M600-series Scout Light with tape switch. We tried this same setup with the mount on the left side. The Scout’s much larger tightening wheel wouldn’t clear the handguard at all. All in all, we liked the Arson Machine Offset Light Mount, but it does have a couple of idiosyncrasies in terms of light fitment. But it works as advertised and the 90-degree orientation is something we hadn’t tried before. And for less than $50, it manages to deliver high quality as well as good fit and finish while still being friendly to most wallets.
