We have gone to great lengths to design the most reliable and dependable triggers on the market and we are constantly striving to improve the safety and performance of all TriggerTech products. However, TriggerTech Triggers are precision mechanical devices and they can be damaged. Here are some examples of Damaged Triggers that have come thought our warranty department:

See below for a detailed description of each. A damaged trigger could be or become unsafe. Shooters are reminded:
  • Your triggers pull weight should not change. A sudden or gradual change in pull weight is a sign that something is not right, and your firearm may not be safe. Stop using your trigger and contact TriggerTech Support (support@triggertech.com) 1-888-795-1485.
  • If you notice a change in your triggers ability to hold the firing pin when closing the bolt do not try to overcome this by increasing pull weight. Stop using the trigger immediately and contact TriggerTech Support (support@triggertech.com).
  • Always safety check your equipment prior to use and using live ammunition.
  • Always follow the NRA Guns Safety Rules.

The following are conditions that may damage triggers

Pierced Primer / Overpressure

What is a pierced primer?

A pierced primer is when a primer fails to maintain intact during the shot. When this occurs high-pressure gas blasts out of the pierced hole and fires back into the firearm which can cause damage to the firing pin, breech face, action, and/or trigger. Essentially, some of the energy that is used to fire a bullet is directed backwards thought the primer into your firearm.

What is overpressure?

Similar to a pierced primer, except that the primer does not burst. Overpressure can still damage rifle components.

Brass with ejector groove marks – this it is a sure sign of high pressure (source).

What can happen?

The following triggers were damaged by pierced primers: 

There are different severities of pierced primers/overpressure events that can range from less sever where no damage occurs to catastrophic where the firearm will be destroyed.

Note: certain equipment may reduce the severity of a pierce primer. This action has a gas vent which is designed to reduce the impacts of a pierced primer on rifle components. Your friends experience with a pierced primer may not be the same as yours. 

What should you do?

Always inspect your brass for signs of overpressure or pierced primers. In the event of overpressure/pierced primer, you should have your firearm inspected by a qualified gunsmith before using it again. Shooters are reminded:
  • Your triggers pull weight should not change. A sudden or gradual change in pull weight is a sign that something is not right, and your firearm may not be safe. Stop using your trigger and contact TriggerTech Support (support@triggertech.com) 1-888-795-1485.
  • If you notice a change in your triggers ability to hold the firing pin when closing the bolt do not try to overcome this by increasing pull weight. Stop using the trigger immediately and contact TriggerTech Support (support@triggertech.com).
  • Always safety check your equipment prior to use and using live ammunition.
  • Always follow the NRA Guns Safety Rules.

What Causes Pierced Primers/Overpressure?

Pierced primers can be caused by a single or combination of several factors:
  • A “hot” load - loaded with powder charges above the max charge weight and/or powder type.
  • Excessively strong firing pin spring.
  • Firing pin too flat, pointed, narrow or long.
  • Too much gap where firing pin protrudes from bolt.
  • Thin primer cup (especially when combined with a strong firing pin spring).
Certain environmental factors can also contribute to pierced primers:
  • Shooting in wet conditions may increase the likelihood of a pierced primer (water on casing and/or in the chamber leaves less room for expansion during the shot and increases pressure).
  • Shooting in hot conditions may increase the likelihood of a pierced primer (Pressure increases with temperature. Loads tested at one temperature may not be suitable for use at higher temperatures).

It is possible to pierce a primer and not know it?

Yes. It’s not always clear, especially when shooting a stage at a competition.

It is possible to pierce a primer on factory ammo?

Pierced primers are most common with hand loaded ammunition but can also occur with factory ammo.

Untimed Action Damage

What is an Untimed Action (cocking piece and sear)?

In a properly timed action, the impact of the bolt throw is taken by action and bolt handle and the cocking piece only engages the sear once the bolt rotates past the point where it begins to lock. If an action is not properly timed, the cocking piece will impact the trigger sear on the bolt throw and the impact forces are born by the cocking piece and trigger sear.

What can happen?

With an untimed action, the impact forces are shifted to the cocking piece and trigger sear. Essentially, when you close the bolt with an untimed action you are hammering your trigger sear with the cocking piece. This can cause accelerated and unusual wear on your trigger and cocking piece. Excessive wear caused by an untimed action may cause your firearm to become unsafe as you can damage and /or break the cocking piece and/or trigger components.

This is especially true with aggressive or repetitive dry cycling of you action. Cycling an untimed action without ammunition is more sever from a wear perspective than cycling with ammunition as moving ammunition will slow the bolt. 

What should you do?

Ensure your action is properly timed such that the cocking piece only engages the sear once the bolt has rotated far enough that it begins to lock. Seek the assistance of a qualified gunsmith if you are unsure of how to do this.

My action is untimed. What should I do?

Seek the assistance of a professional gunsmith. Some companies make cocking pieces with relief. Here is one from Pacific Tool and Gauge:

Damaging your Trigger when Installing Trigger Pins on Install (Rem 700)

How can I damage my trigger when installing trigger pins?

If you do not follow Step 4 of our instructions properly, you may damage the trigger by attempting to hammer a trigger pin through a trigger pin hole that is not aligned with the action mounting hole.

What can happen?

Damage severity can range from cosmetic damage to the housing to catastrophic damage where trigger will no longer be able to be mounted to the action or function safely. It is possible to cause the trigger to fall out of factory alignment and in this case may cause degradation of the trigger’s safety and/or performance.

What should you do?  

  • Follow our instructions carefully when installing the trigger.
  • Ensure proper alignment prior to installing trigger pins.
  • Do not use excessive force when installing trigger pins.
  • Safety check your firearm after trigger installation.
  • Do not use a trigger that has been damaged by trigger pins during installation.

Cocking AR Trigger after initial install with Safety On SAFE

How can I damage my AR trigger during install?  

If you incorrectly install the trigger in the unlocked position (step 3 of instructions) and then proceed to incorrectly charge the bolt with the safety on SAFE (step 6 of instructions) it is possible to break the ticker component.

 

What should you do?

  • Follow our instructions carefully when installing the trigger.
  • Ensure the trigger is in the cocked position when completing Step 3.
  • Ensure the safety is on Fire prior to charging the bolt when completing step 6.
  • Do not use a trigger that has been damaged during installation.

Dropping Trigger in Barrelled Action

If you drop your barrelled action with a trigger installed it may result in a broken trigger component. 

What should you do?

  • Take extra care when your trigger is installed in a barrelled action.
  • Do not use a trigger that has been damaged during installation.
