What Is Trigger Pull weight?

Pull weight is the amount of force, in ounces or pounds, required to fire the trigger. Or in other words, how hard you have to squeeze the trigger to shoot your rifle. Timney Trigger experts at our Phoenix, Arizona plant hand-test every trigger in its intended action and then set the pull weight at our factory standard, 3 lbs.

If you prefer a different pull weight you simply select it from the drop down above and your Timney Trigger will be customized to your preference.
The #1 reason to replace your factory trigger with a Timney is accuracy. A lighter, crisper, more consistent trigger pull will make you more accurate with your firearm.

Below is a guide for pull weight selection:

2-2.5 pounds
Light trigger pull weights are great for people shooting lighter weight rifles as they can help keep you on target during the shot. Also common weights for target shooting from a bench.

3-3.5 pounds
By far the most common trigger pull weights -this is great for virtually all applications including target shooting, hunting and 3-gun competitions.

4.0 pounds+
Heavy trigger pull weights are good for cold weather hunting or applications where you may be shooting with gloves on.

    I upgraded to the AR 49ER Safety Selector on my M&P 15 Sport. The ambidextrous feature is nice and I like to have access to the safety on both sides of the lower receiver. It is a rugged build and appears solid. It fit into my lower perfectly and works flawlessly.

    49'r Safety selector

    Just installed 49'r safety selector in my Anderson Manufacturing PCC lower. Wonderful to have a safety I can now operate with one hand. I could never put the safety on without using my support hand to do so. Now I can operate the safety as it was intended.

    This safety feels like warm butter when you use it. I can’t imagine any other being on the weapons I own.
