As long as the trigger is held back, the sear is held below the arc ot'the hammer notch. The only thing
holding the hammer in the cocked position is the disconnector,

The Lightning Link accomplishes full»auto fire by pulling the diseonncetor to the rear forcing it to release
the hammer.

The assembled link lays flat in the lower receiveL with the opening at the front fitting over the hook ofthe
disconnector, and the upright resting between the upper receiver take-down pin post. and the bull carrier,

In operation the takedown pin post acts as a fulerum point. When the bolt carrier strikes the top ofthe links
upright the lower end is rocked to the rear. moving llte body ol'the link backward abnul lr'l6 inch, releasing
the ltammer from under the disconnector hook. As long as the lriggcr is held back the rearward movement
ol'lhe bolt carrier will cock the hammer under the disconncelor book. The forward movement ofthe carrier
will strike the upright of the link just as the bolt locks in battery. releasing the hammer. and firing the
weapon. When the trigger is released. the sear will stop the hammer in the eoeked position negating the
operation of the disconnector and the Lightning Link.

Construction

The drawings show the shape and give the dimensions for a Lightning Link that fits in the Colt AR-IS. If
it's to I'll In an aftermarket lower receiver it may be necessary to change the outside dimensions. Either
way, all that’s really imponant is that it fits inside the receiver and ean move back and tonh about 1/16
inch,

When building the Lightning Link without a milling machine I find the simplest way is to cut the long
piece to the length and width Next center punch arid drlll a l/8 inch hole at each comer ol'the large oblong

 

How it works

In normal semi<auto operation the hammer is cocked by a rcamard movement ofthc bolt carrier, as the
carrier moves forward, the hammer is caught and held in the cocked position by the sear located on the
forward part of the trigger catching in the sear notch. on the hammer. If you hold the trigger alter a shot's
fired the sear will not catch in the hammer's sear notch when the hammer cocks because the sear is
depressed below the arc of the hammer notch.

What happens is because the trigger is being held back; the diseonncctor hook is tipped forward and in
position to catch the hammer. stopping it from following the bolt carrier forward When the trigger is
released, it allows the hammer to slip from under the diseonneclor hook and be caught by the trigger sear in
the hammer sear notch. Making it necessary to pull the trigger for each shot.
