What is the difference between a single hook G2 and a double hook. I have a NDS-3 reciever.

Just has a 2nd hook. I believe that all NDS receivers are cut for single hook trigger. To use a double, you'd have to cut the 2nd slot on the receiver yourself.

NoDak doesn't recommend using G2s in that receiver.

Milled receivers usually use double hooks IIRC. The double hook, as the name implies, has two hooks holding the hammer. To simplify production the Ruskies switched to only one hook on the AKM. The easiest way to tell which one to use on a receiver is look at the cutout for the trigger and see if it only has a notch on one corner (single hook) or two (double hook).

Get either a Red Star or a K-Var group. I had problems with the G2 in one of these receivers. Works fine in others, but not in these.

Actually, NoDak does not recommend the single hook in the NDS-3. I have just finished my 2nd Romy using the NDS-3 and G2 double hook trigger and both function test fine (I haven't shot the new one yet, but my older build operates with no problem).

Like it was said above, you just have to cut a second slot in the receiver. The cut should be shorter than the original cut so trigger overtravel is limited. Too much and you may get some problems.

Agreed. It's only the single hook that NDS doesn't recommend in the NDS3 due to the longer slot. If you cut a second shorter slot then all will work fine. Other than that you can pick up a RSA or Armory single hook FCG.

why do they sugguest against the single hook g2 from tapco for their recievers?

It is my understanding that the NDS-3 receiver was originally designed for Century who used their own FCG. The single slot is a bit too long to work correctly with the Tapco single hook by allowing it to have a bit too much over travel. By cutting a second (shorter) slot you can utilize the Tapco FCG and stop the trigger closer to where it should be stopped. I've done the modification a few times...if you are comfortable doing so then it takes all of ten minutes (if that) with a drill press and file to get a good quality second slot.

Another thing you could do to make a double hook FCG fit into a receiver made for a single hook, is shave a  little off the second hook.  That's what I've seen people doing to get double hooks to fit into Saigas, as opposed to cutting into the receiver.

Get the G2 double hook and then look up Gunplumber's excellent instructions on fitting the double-hook G2 to the NDS-3. It's not drop-in but it works perfectly!
