How Does It Work: Lever Delayed Blowback

  / forgottenweapons   Cool Forgotten Weapons merch! http://shop.forgottenweapons.com Lever-delayed blowback is a relatively uncommon action system, although it is applicable to a wide variety fo firearms and has been successfully used in submachine guns, rifles, and light machine guns. It uses a principle of mechanical disadvantage on a fulcrum lever to force a mass to accelerate rearward while the bolt remains closed. This allows the effective weight of the moving parts to be amplified, resulting in a lighter firearm.
