    HKP HK 416, COLT M4 .22 MATCH TRIGGER UPGRADE SPRING KIT

    Posted by Karl Rossman on 29th Apr 2024

    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.

    Necessary upgrade - TAC R1

    Posted by Rick on 27th Dec 2023

    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.

    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.

    After reading the reviews I bought this kit. The factory trigger on my HK416 was pretty heavy although I don't have a gauge to measure it. After installing the kit I would say it reduced the pull weight by at least 1/3. I don't know that it changed the take-up or overtravel but the trigger feels much smoother and more controllable. As others have said there are some things to pay attention to. The excellent video shows a pot metal trigger housing and talked about the four nuts that back up the housing screws falling out. On my 2022 vintage 416 the housing is plastic and is threaded for the housing screws - no separate nuts. Also, the housing screws on my gun are a small Torx head screw - not a socket head cap screw. So you will need a Torx driver set. There is some fiddling required to maintain the geometry and proper position of the hammer, sear, and trigger. And the pivot pins for the hammer and sear don't necessarily want to stay in place so you have to pay attention that the inner end of both pins is in the hole in the trigger housing. The video shows it and I too had to rock the trigger to straighten it so that the near end of the pin also goes into the hole in the trigger housing. And the loose nut that accepts the grip screw also wants to reposition and fall out if you tilt the not fully assembled housing. I did the work down inside a MTM rifle cleaning stand. I would certainly recommend doing all the trigger housing work inside a shallow open box lined with a white towel inside. This is always a good idea to capture dropped or spring-loaded small parts that might otherwise get lost. None of the above is meant to discourage anyone from installing this kit themselves. If you have ever done any AR work or are handy with tools you can easily follow along with the excellent video and do this work. Just be patient and pay attention to how the inside of the trigger housing looks when you disassemble it. All in all an excellent products with thorough and easy-to-follow instructions, and a rewarding result!

    This fit perfectly in my HK416 22lr. For those wondering if it will fit in the 416s with the plastic trigger group housing, it will. The installation steps are the same.
