Cobalt’s patented Dual Drop mechanism is expanding the functionality of the classic AR-15 platform. First, the Dual Drop adds a second forward assist control- mirrored on the left side of the upper receiver and mechanically connected to the right side assist and the bolt catch. By pressing either forward assist, the bolt is released to reload the rifle.
Dual Drop improves weapon handling and reload speed. We put the system’s controls within reach of the thumb of the shooting hand. Operation is as familiar and instinctive to operate as the slide release on a pistol. After a reload, the forward hand takes control of the forearm while simultaneously, the shooter’s thumb releases the bolt. From an empty, locked open condition, a Dual Drop-equipped rifle can be reloaded and back on target faster than traditional AR-15s. We have recorded up to .52 seconds faster than a conventionally equipped rifle.
Our rifles can be reloaded more safely than any other AR-15. The rifle is kept under control and pointing at the target while the bolt is released, and the trigger finger can remain indexed and ready until the shooter decides to fire. Aftermarket “bolt-on” controls, that require use of the trigger finger, have not been proven to speed operation. And these devices may encourage unsafe habits as the trigger finger searches for new and alternative control surfaces. With the Cobalt Dual Drop, the trigger finger’s only task remains that of firing the weapon.
