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

Installed this kit on my Hammerli Tac R-1, installation was fairly simple thanks to the video. I don't have a trigger pull gauge so I can't give actual numbers, but a big difference in pull and grouping is better on quick follow up shots. A+ product!

Once installed, it made the gun 100x better. My gun wasn't the same as the install video, had some different things to navigate but with patience I got it installed. The gun shoots so much smoother, great product don't hesitate just buy it now.

While I don?t have a trigger pull device that calculates the weight of the pull, there is a significant difference in both the weight and ease of pull. The installation however was a pin for the Hammerli. I don?t know what it is, however getting the trigger group assembled after installing the springs was a real challenge even if you follow the instructional video on YouTube to the letter like I did. If you have a Hammerli I suggest you take this to a gunsmith Instead of taking the risk of losing a spring or small part from flying across the room like I almost did. However, as far as just the spring kit is concerned, it is a phenomenal product

This spring kit was easy to install that any DIY could do with a quick YouTube search. Would highly recommend $17 well spent. Trigger is much nicer now.

My Hammerli came with a heavy trigger. These springs made a big difference. I would recommend these on your stock Hammerli springs.

I ordered a trigger kit. For my HK 416 After watching the Install video. It took about 20 minutes to complete. My only heartburn was with the video. And the trigger return spring orientation. It Had A hand in the way. But I figured it out. Trigger works GREAT. Thank you Reid

Great trigger setup. I dont have anything to measure it yet but just by testing the OEM to the new one is a big difference to me. I think for the price, its worth the upgrade on Hammerli R1. I wish the trigger housing was metal but I'm sure it comes from a weight perspective and what not.

Everything went together in my Hammerli and the trigger pull is much improved

Awesome ! Makes a huge difference in the trigger pull in the Walter hammerli

Worked well in my Hammerli TAC R1. It has a plastic trigger housing not the metal one that the HK has. Reduced mine by the advertised 3 lbs. from 8 to 5 pounds.
