Very simple to do on your own, just watch Mcarbo video and it takes about 10 mins. to do.
Saw this trigger spring on a forum somewhere with a positive recommendation so I looked up M-carbo. The listing showed it was primarily for a Mossberg but in the comments someone mentioned it would also fit a TriStar G2 Viper. I ordered it and the evening it came I decided to install it. I had done this before to another gun so I was somewhat familiar with the process. So, aside from finding the tools, the install took maybe five minutes. Yes, it’s that simple. Two pins out. Install spring. Two pins back in. Done... I don’t have a trigger pull gage so I can’t say precisely how much of a reduction there was, but I can say this. I could hang the gun on my finger, by the trigger and I’d have to jiggle it to make it go off. After install, the trigger would go off before the entire weight of the gun was on it. Made that trigger as perfect as a factory trigger, without polishing and lapping, is going to be. The reduction of pull weight is in no way near the “danger zone.” Just a comfortable reduction that will make your shooting experience that much better...
Great product , fast delivery and super easy to install. I bought this for my 6 year olds turkey hunting gun , because the factory trigger pull was too much for him . Now the trigger is crisp and easy for him to pull and stay on target . I’m very happy with this product .
Spring work as advertised. Reduced trigger pull from around 6.5 lbs, to a little less than 5 lbs. Easy install after watching the video.
Easy install and does the job.
Used this spring in my Tristar 410 viper and it dropped the pull from 61/2 lbs to 5lbs.Happy with results.Would do again
I used this on my new Tristar viper G2 .410 turkey. The Trigger was at 6 1/2 lbs before the new spring. Once installed and some synthetic grease it took my trigger down to right around 4 lbs. My 5 year old is now able to pull it with easy now. Install was pretty fast and easy.
This will work on the tristar viper g2 12ga, trigger pull feels alot better
Product installed in minutes with no prior experience. Reduced trigger pull tremendously and was worth every penny.
This spring kit works perfectly in a TriStar G2 28ga. Adam was very helpful and prompt in helping get this spring kit. Fast delivery. A+
Completely my fault but I ordered this kit in hopes it would work given the similarities of the Mossberg SA-20 and Weatherby SA-459 trigger assemblies. The gun will fire and the trigger pull is crisp and greatly reduced but the trigger will not reset after firing. Too bad because the SA-459 is an awesome turkey gun and deserves an improved trigger kit.
Easy to install and happy with the changes.
Great fast shipping, very easy to install, dropped my sa-28 trigger by 3#. Great product! Would highly recommend
Reduced trigger pull by 3 lbs. it was easy to install
I installed this spring in my TriStar Viper G2 410 shotgun after a skeet shooting buddy installed one in his 410 TriStar. The trigger pull on my shotgun was 7.5 # +/- 4 oz. from the factory. After installation, the pull weight is 5.5# +/- 4 oz. I was hoping for a greater decrease in pull weight, but I am pleased with the results. These TriStar Viper G2 shotguns are great guns. The quality at their price point is outstanding. My 410 has had no malfunctions of any kind in over 500 rounds. Planning on purchasing a Viper G2 28 gage, so I bought 2 springs. Thanks M-CARBO . Good product, great service. Bob H
I installed this spring in my Tristar Viper G2 410.I don't have a trigger gauge but the weight of the gun (5.2 pounds) will now break the trigger.It feels so much better.I picked another one up for the Tristar Viper G2 28 gauge that I have ordered.I would highly recommend. Mcarbo service is world class!
