HKP HK 416, Colt M4 .22 Match Trigger Upgrade Spring Kit

The stock trigger on my HK 416 was approximately 12 1/2 pounds straight out of the box! I was absolutely shocked at how bad it was. I ordered this kit after seeing the reviews and it surely delivered. I took apart the ticking time bomb of a trigger pack using the videos that HK Parts has on YouTube and replaced all the springs as well as polishing the sear surface that contacts the hammer. I also used two tiny e-clips to put on the pin on either side of the hammer strut that holds the main spring because I was noticing that as you were pulling the trigger that strut was twisting and causing an unnecessary grittiness between the wiper plate that the spring pushes agaiisnt, as itwas twisting the strut and causing some rear interference with the disconnector on the trigger. Together with the springs and fixing some of these issues, I was able to drop the trigger weight from about 12 1/2 pounds down to 5 –5 1/2 pounds. It really transformed how this gun shoots. The stock trigger is absolutely horrid for any kind of accuracy.

Awesome! Great buy. Triger feels way more better! Much softer and smother. No reliability problems with the rifle. Very happy with this product.

This is a great upgrade at any price and dramatically improves the trigger, just be aware that your technical skills and personal tendencies toward becoming frustrated may be challenged by the procedure. Are you a technical person? If so, it probably won't feel like a huge chore. Are you very definitely NOT a technical person? You might want to get someone who is, depending on how easily frustrated you get doing unfamiliar and delicate work. On the other hand, if you're curious and patient, it's probably not a bad first job to get into it.

installed on a Hammerli TAC R1 .22 rifle. It took me about 10 tries to get the hammer/trieger group back together. Im very happy with the results. It took the gritty break considerably. Haven't measured the revised trigger pull but I'd say 4.5lbs is about right.

The horrible trigger pull was completely fixed with this upgrade. ...but... don't believe what anybody tells you about how "easy" the install is. I was eventually able to do it myself, but you really need 3 hands, and a cat to chase down the parts flying all over the place.

This simple spring kit completely changed the attitude and accuracy of the HK 416 22lr. Best $17 spent in a while!

I haven?t tested lbs pull on trigger but it a definite improvement for a small price.

Video made install easy. what a diffence. Thanks.

Spring kit is a little finicky to put in. Totally worth it for the upgraded trigger.

Pretty straight forward. If you?ve never done this the video they provide is enough guidance that someone who is clueless about firearms can do it. Trigger pull is definitely smoother. Haven?t gotten out to shot it yet.
