Single or double hook?

[masek77]

Can you tell the difference between a double hook and a single hook trigger without looking inside the rifle? Does it "feel" different when fired? Is there an appreciable difference in trigger pull?


I'm hearing there are some problems with the Tapco single hooks in certain AKMs and if there is no discernable difference I think Ill just go with the double hook on everything.

yes, you can tell the difference without lookin into the rifle.....turn the rifle over where you are looking directly at the trigger......it will either have a single slot or 2 slots off the trigger hole pointing toward the mag well, one will definitely tell you it's a single hook.....2 slot may tell you it's a double trigger, but to make sure it is, pull the trigger back, the bottom of the hooks will protrud slightly from those slots, it's easy to see you can't miss it.


if you plan on going with a double hook trigger, you have to cut another slot out in the receiver for it.......all the AKM receivers I have seen are cut for single hook triggers. The only AKs that I have seen with stamped receivers that have been cut for double hook trigger are the chinese ones.

How hard is it to modify for a double hook then?

[16r40]

how hard it is, depends on you.....if you have zero skills with tools, or are inept at doing things with your hands, then it will be very hard

its easy - use files to copy the relief in the opposite side. Double hooks have more friction, but they hold together better and are safer for home builders (trigger hooks wont fall off side of hammer)

Took me about 20 seconds with a dremel and a small cutting thingy to make the notch.

I have been getting double hooks lately because of the extended hook on the NDS3 receivers.

Or leave the receiver alone and grind the underside of the second hook until the trigger just releases. You've just made a low overtravel trigger yet have no visible modification.

All AUSA receivers are cut for the double-hook. I am not big on single-hook on a semiauto. I have some that only contact the hammer with half the width of the hook. The single-hook resulted from butchering the FCG so a dampener could be added to the sheetmetal receivered AKM. Without the auto sear and so-called "rate reducer" dampener the hammer can move back and forth sideways. With a double-hook the ill effects are minimized.
