Installing the TAPCO G2 Double Hook AK-47 Trigger

By CTD Blogger published on in How To

The TAPCO G2 Double Hook AK-47 Trigger is one of the best upgrades you can make to an AK-47. Combat rifles, such as the AK, notoriously have sloppy triggers that require up to 10 pounds of trigger pull. To make it worse, many of the Com-Block semi-automatic rifles imported here have humps on the back of the disconnectors that create horrible trigger slap.

This guide walks you through the process of installing the G2 Double Hook AK-47 on a Romanian SAR-1 rifle. While the particulars here pertain to the Romanian SAR-1, they also apply to most other AK-47 semi-automatic imports, including most Yugoslavian models and Saigas chambered in 7.62×39. This trigger set should fit both stamped and milled receivers. That being said, gunsmithing is required. We do not recommend any of the procedures described here be performed by anyone but a qualified gunsmith.

The first step is to disassemble your AK according to TAPCO’s Instruction Manual. Always unload and clear any firearm completely before beginning disassembly.

In the image, we compare the Century Arms trigger as installed on a Romanian SAR-1.

  • Note that on the TAPCO, the rear of the trigger has more material than the Century trigger.
  • Also note the TAPCO trigger uses a larger pivot hole that requires a bushing (included in the TAPCO kit) to slide over the pin.

The disconnector on the Century trigger group has more material on the rear. Why Century decided to cast the part that way is beyond us, and the result is horrible trigger slap. The TAPCO disconnector uses the traditional Com-block design and does not have the extra hump of metal.

Our Romanian SAR-1 has a single-hook trigger design. Because of that, the receiver only has one notch for the trigger hook. We used a Dremel rotary tool and medium stone to grind out a matching notch on the other side of the trigger slot.

In the photo, you can see that our stone slipped out of the notch and marred the finish a bit. Not a huge deal, and perhaps a bit more care while grinding could have prevented that.

After test fitting our trigger in the modified slot, we noticed some flashing left over from the mold from which the trigger was cast was interfering with the trigger’s operation. We ground off that bit from the front and back of the trigger, taking a little bit at a time and test fitting between grinds until it was just right.

At that point, we reassembled the rifle to dry fire and cycle the action a few times to check for functionality and reliability. One problem quickly arose; the trigger stuck after being pulled and would not reset.

It was not that the notches were not long enough; it seemed the hooks were grabbing on the sides of the trigger slot, as if it were not quite wide enough. So, we disassembled the rifle again and used the Dremel again to take off a tiny amount of material from the sides of the trigger slot.

After reassembling the rifle again, everything worked flawlessly. Instead of a creeping, heavy combat trigger, we had a crisp, clean one with very little creep.

The action cycled well, and range testing showed that the rifle was just as reliable and a lot more accurate.

    K Yeah…………… wait…….what? What the Hell did that guy just say? I don’t know squat about an AK, but just bought one yesterday. A Century Arms Zastava, Serbian. I notice that it says Tapco G2 on the trigger, so I assume that’s to my bennifit. No bayonet lug though, isn’t there some sort of clamp-on lug or somdething out there? Along mid point of the gun, the rear sight has some sort of lever attatched where it pivots. What’s this for? I was hoping I could mount an aperture peep sight, but don’t see how that one would be removed. I thought I read about one somewhere on-line, and thought it was on a dove tail, but mine doesn’t appear made that way. Then, bringing up the rear, the salesman pointed to the two rivets holding the wooden stock in place in my stamped reciever, saying no, I couldn’t change to a synthetic or maybe a 6position telescoping stock. Why can’t I grind off the rivets, use E-poxy and Dremel if neccessary, and make it happen? Anyone know if a particular make/model after market stock would be at least big enough to shave down and slide in the stamped AK reciever? Thanks.

    Your nice blog is merely worth a read if anyone comes across it. Im lucky i did because now Ive got a completely new view of the following. I didnt realise that this issue was so important for that reason universal. You definitely stuff it in perspective for myself, thanks for the fantatic info.
