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

What a difference this spring kit made in my Colt M4 22lr. Nice easy clean break now. Took it to the range and oh my, what a wonderful shooter. It was fun before, but now it's at another level with comfort and accuracy.

A little pricey for (3) Springs, but considering the improvement, well worth the investment.

The springs were perfect. But a challenge putting the trigger box back together. Springs plus honing the seat made a tremendous difference. Putting it back together was a Bear lol I do gunsmith work on the side. Easier on the other guns it fits. If you run into a problem with the Hammerli contact me. Contact me before you take out the four screws.

Went in fairly easy and made a difference in trigger pull for sure happy camper here so far so good

3 tiny springs for $17.49 plus shipping seemed a little pricey! But I took the plunge. It was fairly easy to change and the video was a great help! Putting back together was a little tricky lining up. Once together I pulled the trigger and wow! What a difference these springs make! Made trigger pull smooth and lighter! Great improvement in shooting! I would buy them again in a heart beat! Hammerli tac r1

you have to get this trust me - big time difference in the trigger pull

Easy to install, found out my trigger housing is plastic instead of metal, would like to upgrade that if possible but none the less it makes a huge difference!

The installing of the trigger springs were not that difficult and certainly have a positive effect when shooting the HK416 22lr. Would highly recommend to those considering purchasing the spring set.

Does exactly as advertised. Certainly helps kids and adults alike.

I installed the spring kit and did see a reduction from an average of 8.8 lbs to 3.8 lbs on the trigger pull. I haven?t been to the range yet but do not see any issues with the spring kit.
