You may be wondering if there is a firearm accessory to allow you to shoot your semiautomatic faster.  Of course, there is a device; a binary trigger will enable you to fire faster.  You will realize some guns come with binary triggers installed while others don’t have. So, don’t panic if your firearm doesn’t. Some companies make binary triggers to fit the modern semi automatic guns on the market.

What is a Binary trigger?

It is a device that features two modes of firing; binary and semiautomatic. In a semi automatic setting, one shoots a gun single round fire for each pull of the trigger. On the other hand, in a binary trigger setting, one round fire when the shooter pulls the trigger, while the other fires when released.

How Binary Trigger works?

The trigger system doesn’t give you automatic capabilities. However, it increases the ring’s rate by offering a 3- position on the selector, which fires when pulled and when released as well.  The 3-position selector allows you to switch from safe, semi automatic, or binary state.

When the trigger is pulled on a gun, the sear releases the hammer. The hammer strikes the firing pin to ignite the round in the chamber. The bolt rides back, and the hammer is pushed down to be reset after firing. However, the sear is not in place to capture the hammer but is captured with a small hook. When the trigger is released, the disconnector releases the hammer enabling the sear to capture it again.

Add a second sear that captures the hammer when firing; squeeze the trigger to stop the shot, and release the trigger to release the second sear so the hammer can hit the trigger pin again. When firing the second shot, the recoil and trigger take over as well.

Installing a Binary Trigger

If you are worried about installing a binary trigger, then it is similar to any other trigger. The only difference is the addition of spacers on either side of the trigger, and the slave pin knocked out as you install the trigger pin.

Step 1: Get the necessary tools.

First, gather all the necessary tools you need. They include a hammer, a thread locker, a flat and cross screwdriver, and protective glasses. Depending on the trigger, it determines the tools you will require.

Step 2: ensure no oil residence on the trigger

You should make sure that there is no oil residue on the left side of the lower receiver that could prevent the protective adhesive from sticking. If there is oil residue, it can be removed from the surface with alcohol or another liquid.

Step 3: Fall out the slave pin.

Since the binary trigger comes almost assembled, you only need to fall out the slave pin. Now, reposition the disconnect so that the plug can be placed on the right side of the trigger. However, don’t move the slave pin past the disconnect until the IDS spring is in place.

Step 4: Insert the IDS

Insert the IDs via the pinhole on the left side of the trigger. Then guide the IDS spring back into the IDS slot. Choose a pick to squeeze the spring so that the pin can be pushed to the trigger’s left side.

Step 5: Lay the spacers.

You can place the spacers on either end of the binary trigger with the half-round portion facing up on the outer ends.  Next, wrap one trigger spring around the assembly.

Step 6: Install the trigger pins.

Insert the first trigger pin to the left side to hold the left spacer and the second pin to the right side. Make sure the flat end of the trigger pin goes into the right side of the receiver and gently tap it until the other pin and the secondary pin are out.

Step 7: Wrapping the hammer.

Wrap the hammer using a hammer spring to cock and ensure the safety switch on the receiver’s left side. Install the safety latch into the hole in the receiver. Put on the safety spring, handle and grip screw.

Step 8: Attach the short paddle to the safety selector

Attach the short paddle to the safety selector with the screw. Use thread lock on the selector bolt and tighten the paddle bolt with a wrench.

Step 9: Inserting the buffer.

Put the buffer and buffer spring into the receiver extension. If the trigger works well, you followed the steps correctly; then the weapon is ready to work.  In case something breaks or crashes, you need to reread the manual.
