Most Helpful Positive Review Great service
I had a self inflicted mistake on a recent order. Customer service was great and fixed it immediately.
Most Helpful Negative Review Disaster for me
I've been putting triggers in my AR's for years, and I have never had a disaster like this one. It just takes a few minutes to switch out a trigger, but this took me hours. The instructions are not helpful. The Rumble video is. But after trying this trigger in 2 different rifles, the trigger doe...

poor assembly

by Tom T, Verified Owner from IN, United States Written on June 29, 2026
This is my second Franklin Binary. If I had not bought one prior I would have sent it back. Installation is really easy. However function check failed. After numerous failures I took the IDS apart and found it had been assembled incorrectly. Whoever assembled just forced the shipping pin through breaking the IDS spring. They were thoughtful and at least put another one in with the safety selector.

OK at best

by WayneTX, from TX, United States Written on May 30, 2026
I don’t like writing unfavorable reviews. But it’s honest. Installation was OK until it came time to install the 3 position safety. It would not fit. I had to use a fine grit Emory cloth to sand it down and reduce the diameter. I finally fit it to my Springfield Armory Saint Victor receiver. Operation was clunky. I personally didn’t care for the binary operation. I guess I could get used to it, but I tested the ability to cancel the trigger release shot, by holding the trigger and moving the safety to the single fire position. I couldn’t, so once pulled I had to allow the release shot, like it or not. Overall safety operation was gritty. I’m going to replace this trigger with an FRT.
Pros:
  • works
Cons:
  • Fit
Would recommend: No

Legal Fun Switch WO/Spending a Fortune

by JD Daily, Verified Owner from NV, United States Written on November 4, 2025
I occasionally have a lot of fun reliving my VN experience burning mass quantities of 223 55 grain cartridges shooting rates in the Cu Chi dump.
For defensive use of an AR-15 it delivers fast & accurate double taps once you master its' use. Otherwise it turns an AR-5 into a bullet hoae.
