Fantastic Trigger

Only complaint is that the gun took forever to take apart and put back together but fortunately they provided a installation video to help me with that. A little bit of sponginess before a crisp break. Better than any tavor or aug trigger for sure. cant wait to try doing some rapid fire with it. 10/10 must have for the RDB

The stick trigger is great, but this makes it amazing

This drastically reduces the weight of my trigger. I highly recommended this for anyone looking to get a lighter pull. The installation is a little tricky, but the install video is very useful and informative. It took me about twenty minutes to install.


Simple, cheap, yet an absolute must if you own an RDB

Part came in no time flat (that could be that it was shipped less than 50mi away) and included some cool brand decals and such. Nice to support a local company!

The part itself was on par with the quality of oem if not beyond it. The video made on the website was super helpful and intuitive and made install a cinch.

Once installed the trigger pull is significantly lighter than the stock 5lb.(Or so) trigger spring although that one isn't a slouch either for a bullpup. The most noticeable change is the reset being improved and the much smoother takeup before the hammer is dropped.

All in all, great product for the money and 100% useful if you're looking to improve your RDB. A no brainer. Customer service is also quite impressive!

WOW! Really great trigger upgrade for a really cool rifle!

This is the upgrade you want if you want a competition grade trigger for your RDB! It took me about 35-40 minutes to install as there are a lot of screws to undo and redo. Good needle nose to compress the spring on the spring rod is essential!

Sorrento, LA

Easy install great feel

Actually installed this before I got to go to Range but did dry fire before install to get a feel of before and after and it is much improved great job mcarbo on a great install video
