With the wave of popularity bumpfire devices earned over the past couple of years, many of you are likely familiar with Slide Fire bump stocks. In addition to the new expansions to their product line for 2014, Slide Fire brought a prototype into which they’ve been putting some time. While functional, the design is so new, it doesn’t yet have a name. Casually, they refer to it as the “bump sled.” When I saw someone shoot it during SHOT Show 2014, it certainly caught my attention. So, I asked one of the representatives for Slide Fire to tell me some of the Bump Sled’s story.
The design for this prototype makes use of essentially the same Slide Fire Solutions technology that utilizes the firearm’s recoil to assist in pulling the trigger faster than normal. The result is a fair simulation of full auto fire while remaining a non-NFA device. The stock, instead of remaining fixed/immobile, has a component that can move back and forth. Effectively, this allows the force of recoil to push the receiver backward, and as it hits the limit of the stock’s rearward movement, it bounces forward. The stock has a nib that extends to the side of the trigger guard. During fire, the shooter holds their finger on that rest, and as the recoil redirects the receiver forward, the finger remains to press the trigger again, continuing the cycle.
Instead of requiring the shooter to hold their finger in the trigger guard, the Bump Sled device uses a thumb trigger. To fire, the shooter holds the two grips, and presses their thumbs on the trigger plate, which pushes the rifle forward on the “sled,” pressing the trigger against the trigger bar. The sled performs the same recoil-driven action that the moving slide does on the original stock, allowing the shooter to bumpfire, but without requiring them to shoulder the rifle.
But, why develop such elaborate machinery if it essentially works the same as their standard stock? The representative from Slide Fire who introduced me to the Bump Slide expressed that it was Slide Fire’s goal with this design to make their products more accessible for those who may have difficulties using their technology with their standard product. The Bump Sled prototype is an option for the disabled to enjoy bumpfire. Yep, the Bump Sled can be fired from wheelchair.
What do you think of the idea?
