Franklin Armory 5550 Binary Firing System BFS Trigger Gen 3 Metal Black

Franklin Armory's revolutionary Binary Firing System (BFS) is ideal for three gun competitors, tactical shooters, and recreational enthusiasts. It features a three position selector - Mode 1 for Safe, Mode 2 for traditional semi-automatic Mode, or Mode 3 for Binary Mode. In Binary Mode, the firearm will discharge one round with every function of the trigger, whether a pull or a release. A user can negate the round that would otherwise be fired during the release function by moving the selector back to Mode 2 and then safely releasing the trigger. Franklin Armory's BFS is easy to install with no custom fitting. The BFS Gen 3 offers a trigger pull of 4.5 lbs. (+/- 0.5 pound), the release phase now has a positive reset, and an updated design eliminates backup disconnector. The stronger buffer spring (included) reduces the possibility of hammer follow. It works in Franklin Armory's F17 series in .17 WSM without modification. It works on .22LR and 9mm uppers without modification. The BFS works in every AR application: AR10, AR15, MPX, etc.

Great trigger. A little crisper than a milspec trigger. Easy to install and easy to use. Had to swap the buffer springs a few times to dial in the right tension when shooting more rapidly but the kit came with several to use so it was an easy fix. The screw holding the safety switch comes loose after frequent use so a little lock tight would be recommended if you don’t plan on swapping it out often. Would recommend to anyone looking for a binary.

Installation was not too hard and it livens up your AR platform Firearm no doubt. Thanks Franklin Armory!

Be careful with the screwed outer end of the safety selector. Mine came loose after firing about 3 mags of ammo and I could never find the part. Now needing a replacement for that part if this trigger assembly. It was fully secured and tightened fully prior to use. Besides that very nice trigger and works very well. They got fix this part to where it doesn't come loose so easily then it'll be perfect!

Very easy to install, there is a great video on the manufacturer page if you need help. Shoots amazingly.

Good trigger. Easy install if you've ever dropped in a trigger before.
The binary function doesn't always work. It seems a light / or extra hard pull of the trigger doesn't allow for the hammer to be captured in the first stage of the reset.
This doesn't induce a malfunction or interfere with the cycle of operations in any way. It just means the hammer wont fall again upon release of the trigger.
(Keep in mind my sample size is one, so this could be a one-off problem only I am experiencing.
As for the semi-automatic setting, 5lb on the pull scale with no take up and a very clean brake. (Without CLP or being worn in.)
All in all, definitively worth buying.

It only works as Binary on my Sig MPX K...the semi shot is having FTE & FTF...but the Binary is a BLAST and fun to shoot ...

I installed this on a 10" suppressed AR build with a Maxim CQB stock - the kit comes with extra springs to tune the bolt, but everything worked great just by dropping the trigger group in. It does need the AR to be clean (hard to do with a suppressed gun). Quite honestly, more fun than I expected. Well worth the price.
