HK 416 & Colt .22 Match Trigger Upgrade Spring Kit

SKU: HKP-17340
HK 416 .22 & Colt M4 .22 Match Trigger Spring Kit - Set of 3 Springs

The HK Parts Match drop-in spring upgrade set will enhance your HK 416's trigger pull to an even smooth, crisp, and lighter pull that will promote better control, which in turn promotes consistent accuracy. This is accomplished by dropping the trigger pull of your HK 416 .22 by an average of 3 pounds. Each three part precision calibrated match spring set will deliver consistent force through the entire compression/release cycle to give you a lighter, refined trigger without sacrificing the reliability of your rifle. The high strength aerospace-grade springs are carefully made to ensure that you get consistent energy output every time you pull the trigger. You can also be assured that this spring set up will not degrade the ignition systems reliability.

  • Reduces trigger pull by 3 +/- Lbs
  • Provides a consistent, crisp trigger pull
  • Drop in spring kit that requires zero gunsmithing and a breeze to install

The HK 416 .22 LR was made to have fun with, and this spring set will make putting rounds down range a lot more fun! The match spring set can drop it to 4 lbs 6oz, or go to 4 lbs 8oz in the heaviest scenario. As measured The average I got was 4 lbs 5oz on the HK 416 .22 with the new match spring kit, and 7 lbs 10oz average with the stock springs in place.

Each match spring kit includes the following springs for direct replacement:
  • Match trigger return spring
  • Match sear pressure spring
  • Match hammer spring

  • HK 416 .22 rifles & pistol models

"Colt 22lr M16 SPR"

Chris Parrotta on 5/1/2016 5:08:59 PM

Overall Product Rating:


I ordered this spring kit for my Colt M16 SPR with a 21.2 in barrel. I used my trigger gauge before installing and it was maxed out before it went off. The max on it is 8.5. so I'm not sure what it actually was. Watched the video on the site before I installed the spring kit. After installing it the gauge read 6.5 lbs. I was extremely happy it drop down. After that I tried it out on my 4in sheet target at 100 yards. Then 180 yards with mil dot Nikon scope. I couldn't believe I was hitting a targ... More details

"Good Product But Installation Can Be Tricky"

Quinn on 11/22/2016 11:29:29 AM

Overall Product Rating:


The springs do exactly what you want them to. My trigger is now lighter and my shot is better. Definitely worth the $17. If you don't have a full toolbox or aren't familiar with rifle insides, the installation can be tricky. You'll need an extended 4mm allen key for the grip and a torx head for the trigger housing. The video is great but there are a few things that aren't exactly clear. I had to redo the spring installation about 3 times because I put the safety catch back in incorrectly. The sa... More details


"one works, one don't"

Ordered two sets of the spring kits to lower the trigger pull on KH416D, my buddy has the same AR and he installed one set on his and his works great, dropped it down to about a 4 pound pull which he is happy with. We installed it on mine and there was hardly any difference from my old set, still has about a 8 pound pull, not what I was expecting. Contacted HK and didn't get any results from them as to why or if they would send another kit, they only gave me a contact for Wather which led to now... More details

A 5 pulls average weight of 9.99 lbs., straight out of the box, went down to 6.70 after installing the spring kit. In a perfect world, it would have been nice to have additional kits (-3#, -4#, -5#) that would offer a variety of weight loss. Good luck getting the trigger assembly back together, you'll need it. )


"Colt M4 22 trigger pull"

Dave on 2/2/2016 9:45:17 AM

Easy project. When I measured the pull from the factory it maxed out my wheeler trigger pull scale somewhere above 8.5lbs. Suspect it was around 10lbs??? After changing out springs and no other mods it registers around 5.0. I would like to try Slide Fire on it - have not yet tried it out. Recoil probably not enough to drive the bump fire, but maybe. If anyone has any luck with Umarex Colt M4 22 and the Slide Fire let me know.


"416 Match Trigger Upgrade"

Rob on 11/13/2015 5:07:53 PM

Overall Product Rating:


Not sure if it is typical but this trigger upgrade took my trigger from 8.5 lbs to around 2.5-3 lbs. Had a little trouble getting it to work because the tab on the trigger off just a few degrees and my bolt wouldn't open. It took me 45 minutes to realize what the problem was. I had to pause the video many times and study it to figure it out. Other than that I love this upgrade.

"416 .22 Match Spring Set"

M.McPherson on 2/28/2016 9:01:56 PM

Video is comprehensive enough to get the install finished. Very light compared with stock. 1/2 the pressure or less. Makes for very smooth trigger break and faster shots overall. Highly recommended.


"Best $20 Purchase"

Best $20 purchase I could have made...reduced trigger pull on my HK 416d by half. Video is a great help. I snipped a still of the completed assembly for reference before doing the install. Must add another 5 stars for HKparts extremely fast service.
