Flawless working order on psa akv-9 - Franklin Armory BFSIII AK-C1 Trigger - Binary Firing System for AK Platforms

TL;DR: fits like a glove into the PSA AKV-9 with ease. Semi-easy install, no jams/misfires after 1,000rnds

Longer version: I was a bit hesitant after reading the negative reviews on how well this will work, but after using it myself and going over it with some tedious manner, it hasn't failed me at all. The only few problems I ran into while installing, but to get the main thing out of the way, there is a rivet at the bottom of the receiver that sits underneath the item. If it's sticking up, you'll have to cut it down until it's flush or just barely. If not, the trigger will sit at an angle and will cause damage to the thing. Fortunately, PSA already cut the rivet down, so I didn't have to.

The other issue was the hammer. It was ever so slightly misaligned and took a bit of fiddling before it finally got in. When pushing that pin in for the hammer, push down on the right side of the hammers spring while pushing the pin at the same time for it to fully go through.

Next, was the retaining pin for the hammer, which the AK-9 I have has a blind spot, so it was really more of feeling around until it 'clicked' in and a bunch of awkward head tilting and light adjusting.

The third was the selector switch. Which I thought it'd be as simple as putting it on 'safe' and then tightening down to be done. Not quite. Put it on safe, tighten down, then on 'single fire', tighten again, then on 'binary', tighten down again. Then it'll all click together just fine.

You will leave out more parts than you started. That's okay. The rivet boss that sits in the pistol grip will be left out. The original retaining pin that came with the AK will also be left out, and the rear pin is also left out. Congrats, you have more items to work with on your next AK.

The Binary works exactly as intended with practically no issues at all since installation. It definitely beats out FRT's. 5/5, would absolutely give 6/5 stars because it made my buddies smile like they just threw on the giggle switch when using it, too
