The SlideFire stock is an idea that pushes the boundaries of what the ATF considers acceptable for a Title I firearm. Without diving into the world of the National Firearms Act, a Slide-Fire stock is the closest you can get to a fully automatic weapon of your very own. For the most part, these stocks are just a range toy: With no spring to automatically return the gun to the firing position, constant forward pressure is required to continuously activate the trigger. This makes them impractical as a serious weapon, but quite a lot of fun to shoot.
However, Ian and Karl over at InRange thought: What if you could use the SlideFire as part of a system to create a weapon that, at least in certain circumstances, approximated the capabilities of a squad automatic weapon (SAW)? To that end, they developed the “Poor Man’s SAW”.
How practical is such a setup? Well, that probably depends on who you ask, but at least in some situations, the InRange SAW comes impressively close to the real thing.
