HK416, Colt M4 Spring Kit - .22LR - Match Trigger Upgrade

Easy to install and big results. Trigger definitely lighter and less gritty now. Thanks!

Excellent Product. Reduced the trigger pull. It was fairly easy to change and the video was a great help! Putting back together was a little tricky lining up. What a difference these springs make! Made trigger pull smooth and lighter! Great improvement, you can definitely tell the difference.

I purchased this to install on my Walther Hammerli Tac R1 and it definitely reduced the trigger pull from about 8.5 lbs to about 5.5 lbs, and made the trigger crisper with a little less take-up. Installation on the Tac R1 is slightly more tricky because the factory trigger group while being dimensionally identical to the HK 416 22LR trigger group, is plastic, not aluminum as is the HK. And there is one extra pin in the Tac R1 trigger group which looks like its fixed in the HK. This makes the spring installation a little more dexterous a job on the Tac R1. It took me about 3 times reassembling it with the springs popping out on the first two tries because of that pin. Start to finish it took a little over an hour. Other than the installation which is clearly a little more tricky with the Tac R1, I love the product.

Trigger set made such a huge improvement in the trigger pull. Easy install; should have come from the factory like that!

Took it to a HK Gunsmith. Less than a 30 minute job. Big difference from the upgrade Match Spring Trigger Upgrade than the OEM Factory trigger. Fantastic shooter now.

Boggles the mind how a manufacturer can assemble a trigger group and fail on such a simple item as the springs. Night and day, do not hesitate to buy this set. Parts do want to fly all over the place, so go slow and easy, for sure polish up the sear, and disconnect. Some good tips on YouTube for how to.

Just what I was looking for for my HK416. The video made the task easy. Trigger pull was cut in half by the new spring kit.

The HK 416D is a great rifle but the 9 pound trigger pull is excessive. With this kit I'm guessing it's down to 4.5 pounds. Easy to install.

Well worth the money to take my stock trigger from 8#s 6oz to 4#s 2oz

Worked perfect most definitely improved the trigger don't own a pull guage but I'd say cut the pull close to 1/2
