  1. Brian S

    Great rifles with two handicaps- no QD sling attach points, and a garbage factory trigger. The Shooting Sight trigger is such a vast improvement from stock that it’s hard to believe it’s the same rifle. Trigger went from 12lbs to around 4lbs with a very crisp break. It’s not cheap, but no great trigger is and you definitely get what you paid for here. Installation can be tricky, but if you can change your own oil, you can manage this.

    In my opinion, this trigger is a mandatory upgrade for the ARX100.

    Glad someone finally came out with an improved trigger upgrade. Could have had better instructions, (pictures), but still did it with his u-tube video, even though there are some differences. The trigger pull is just right! Love the gun even more!! Now waiting for more barrels to come out.

  3. William

    Easy swap out and trigger pull is right at 5 pounds and it is crisp and clean….The best up grade for the ARX100…

  4. Brent C. (verified owner)

    This trigger will not disappoint you. Such a vast improvement over the stock trigger that it isn’t even comparable. Breaks nice and clean and has a very positive reset. It also retains the factory drop safety function.
    Money well spent, and Art is always good about answering any questions and concerns you might have.
    Great kit, great service and great pricing. That’s how you do business properly.

    Trigger pin may require some polishing, in my case it did. But the trigger and replacement parts are extremely high quality. I would give this 4 stars just because the you tube video has different variations from the prototype model. but the product is so fantastic I have to give it 5. Followed the instructions after having the trigger pin smoothed and now have one of the best triggers in any of my AR style rifles. Worth every penny.

    I had a little trouble getting the results I had wanted with my ARX. Art worked with me and my trigger and it now feels better than I could have hoped for. Extremely happy with the quality of this product and overwhelmed by the customer service.

  7. MICHAEL W SYDNOR (verified owner)

    Trigger is a huge improvement over the factory trigger. My groups are considerable more consistent now. The instructions leave a bit to be desired though. A video with the final version of the trigger would be great.

  8. Nick Z. (verified owner)

    Received the trigger in good time. Only two issues; the packaging was only a thin white bubble envelope (would like to see more padding) and there was no instructions included in the shipment. I emailed and they did respond within a day, giving me the instructions and apologizing for that. So that’s good, but as others have mentioned, pictures would be nice and I did note some gaps in the instructions but I was able to figure it out. Went to the Range and it shot well. My groupings where a little better. Overall I am pleased with the quality and customer service.

  9. Travis

    Really good trigger. Well worth it and makes the rifle that much better.

  10. Jeff E Rogers (verified owner)

    This turned my Beretta ARX-100 from a potentially great rifle into a really great one. The difference in it and the factory Beretta trigger is like night and day. Well worth the cost. Installation is easily managed if you use the directions, watch the prototype video, and have even a modicum of mechanical ability. If you’re thinking about getting rid of your ARX-100 because the trigger is so bad, buy one of these and save yourself the headache. Great product!!

  11. James franklin (verified owner)

    Well worth the price. I found it easy to install..and a dramatic improvement over the factory trigger..

  12. Tim W (verified owner)

    My factory ARX-100 trigger was not horrible, but I wanted a lighter than the 8.5 pound factory trigger in this nice rifle. Art’s ARX-100 trigger is very nice quality and it is a perfect fit with a 3 pound lighter pull and super crisp and smooth. I had a question about the trigger and the detailed answer was very prompt and helpful. I recommend this for anybody with an ARX-100 who actually shoots it and I happily recommend Shooting Sight.

  13. Mariano (verified owner)

    I love this trigger kit! It’s a vast improvement over the OEM version with a much smoother and lighter pull. The installation video was helpful, although an update would be nice since some of the production parts are slightly different from the prototype. While you can install the trigger components as shown in the video, I eventually found it easier and less time consuming using a padded vise to hold the lower receiver. Overall, a wonderfully engineered product that only serves to eliminate the complaints associated with the OEM trigger, while increasing the “fun factor” when plinking with the ARX-100!

  14. Bob (verified owner)

    Excellent product. Easy to follow instructions included. Texture on the trigger is a cool upgrade and of course the reduced pull weight is exactly what this rifle needs. Shootingsight was very fast to respond to a question I had also.

  15. Vic Suarez (verified owner)

    This is what the AR 100 was needing…. what a difference from the OEM and this trigger. I would recommend this any any other product from shooting sight to my friends. The customer support is top notch….

    I received the kit a couple of days ago and the finish on the machined parts is very nice. The added texture to the trigger hook is a nice touch (looks like some form of rhino liner) and the added tools are also a welcome addition. I am looking forward to installing this trigger in my gun. Here’s the caveat tho. The parts kit has changed. I’m assuming Art has made modifications from usage/ testing and customer feed back but with the new parts selection the original install video is less than helpful. I did not receive any instructions w the package, just the kit and I can’t find a pdf or vid on the new install. Can I get some help here please Art?
    Thx E.

  17. E. devito

    *edit unavailable to append last post.
    I found the PDF but could use some images ( I assumed it was the original install instructions as its dated 2016)
    Jobs done but it’s a challenge . That being said it’s a frickin sweet trigger. Thx for putting it out there Art.

  18. Brian Somerford

    Just finished installing the trigger and whoa…this is a game changer. Only downside is that it’s a bit of a pain in butt to install, but if you’re mechanically inclined shouldn’t be too much of an issue.

    If you’ve got an ARX, this trigger is a must have. Very crisp on the pull and very well built. Thanks Art!

  19. DGonzo

    So I would actually give it 4.5 stars, because most of the pain is the actual process of swapping the trigger like most have mentioned. I will say after doing it once if I had to do another it would be much faster since dealing with the pains with the first. I have built may AR’s and worked with many parts of an AR and can build them very quickly from stripped lowers and uppers to full functioning rifles as a point of reference….this trigger took me 1hr 30 min. That was mostly getting the trigger/washer/pins all lined up without falling and re-reading and watching the prototype video just to make sure. I do agree a new video for the product is HIGHLY recommended, or pics in the instructions. But the finished product is well worth the work, so 4.5 stars because it can be easier with some updates for the user.

    I installed my new trigger yesterday and WOW what a difference! Smooth as silk. Great replacement and an unbelievable upgrade.

  21. States R Aycock III (verified owner)

    Trigger is great!! Talk to the owner while he was walking his dog answered all my questions……Trigger took about an hour to install (my 1st ever). Did I mention the trigger is Great!!! Service was a 10 with good packaging, highly recommend!!

  22. Adam Walters (verified owner)

    Art is a helluva engineer! Great trigger. Did the install my self. Youtube video was great even though it was outdated but was great for visuals of point out landmarks.

  23. Mike Rouse (verified owner)

    Significant improvement in the trigger. The factory ARX is clean but heavy. The RPS trigger cuts the total pull wight about in half. Very crisp and improved accuracy. With the factory trigger, there were times I checked to see if I was empty because the pull was so heavy. Installation wasn’t bad. Definitely will help if you are mechanically inclined and know your way around the weapon before you start.

  24. CLARK BAKER (verified owner)

    Must have upgrade. Great product and support by Art.

    If you aren’t familiar with fire controls or very mechanical and meticulous, take to your gunsmith.

    Buy a pin punch that can remove the roll pin holding the right safety selector to the shaft. It can be used to press out all the other pins.

    If you’re not familiar with FCGs, take Good pictures of how things are currently oriented, springs are seated, etc. Use as reference but not gospel as the kit has variances. Watch the youtube video as a guideline (it’s helpful, but some items have changed). Read the instructions. Watch the video again (it’s short), and then get carefully to work.

    When testing the FCG that OUT of the rifle, make sure that the hammer is not half cocked as that made my safety hard to turn. Don’t let the hammer Bang forward on the plastic.

    My 2cents from someone quite mechanical, but a FCG novice.
