I'm thinking about getting a binary trigger
Recommendations? Can they be used for piston ARs? Reliability? Three position binary triggers: Franklin Armory BFS3 $429 Fostech Outdoors Echo $479 Digitrigger with PR mode $599 Evello Mortem EM88 DT $250 Two position binary triggers: LGW Liberator Bidirectional $250 Double Tap Arms AR-15 DT $199 |

I have the Fostech in my ar pistol. Took a little shooting to get my bolt to slide in the new carrier freely (wouldn't always go into battery when firing) and now it works fine.

I didn't realize the Digitrigger was shipping, has anyone done a review of it yet? It seems like the most promising to me if it works like it's supposed to.

I just sent digitrigger a message asking about the max allowable ROF. I know it's supposed to cut you off if your going too fast. It would be nice if they had different options for max speed. I would put a light weight carrier in and cycle it at 900+ RPM.

I just got an email back from digitrigger and it's electronically limited to
They also said a faster version would be available later, but it's still in the works. This will be nice for guys who want to run a lightweight carrier or shorter gas system and keep their cycle speed up. ETA: I put the wrong speed down. 780 is the current limit. |

All I keep thinking of now are those e-triggers you can get on paintball guns

With these products getting better and better they need to just do away with the full auto laws. They are pointless.

I wrote the wrong speed limit earlier. The correct number for the digitrigger is 780.

Both are nice but have differences. First if you want this trigger for an AR9 the ECHO wins hands down. I have had 0 hammer follow with the ECHO on my AR9 setup. For piston the jury is still out on the BFS3 becuase I had hammer follow issues with my blackout piston but Franklin Armory recommend changing up a few things to get it to work I have not done that yet. The ECHO on the same piston gun ran fine. I had to dremel off a little on the carrier but it was not a big deal. The ECHO semi trigger is great but the ECHO takes a little getting used to. You have to pull it all the way back to activate echo mode on the release. The BFS3 imo has a better binary trigger but the semi mode is like a mil spec trigger. The trigger lock is the best feature of the ECHO because it stops all hammer follow without tuning the rifle. To the best of my knowledge the ECHO and BFS are the only two triggers that have had the ATF return letters on there legal opinion. The ECHO is public but does not have a letter for the trigger lock design and Franklin Armory says the have an? approval letter for the bfs but they will not release it I wish theyd repeal the Hughes amendment so we could do this right |

I ordered an Fostech and a BFSIII. I received my BFS3, but lost patience after 7 months with the Fostech. I am using the BFS3 in a 14.5", carbine length, 5.56 with a standard buffer, and it works like a champ. Nice trigger in semi mode, and binary rocks.
P.S. While I canceled my order with Fostech, they were super nice to deal with and refunded my money no questions asked... |

Gimmicks. Do not waste your money. Just get a nice lightweight single-stage or 2-stage trigger and have fun.

Once you shoot one you'll take back that gimmick thought. The BFS3 and ECHO are NOT gimmicky hellfire devices. I like my hiperfire 3 gun trigger but it's not comparible to the way the BFS and echo work. View Quote |

I finally took out my BFSIII last week and will say it works so much better than the bumpfire stocks that I own. Not inexpensive, but much cheaper than FA.

Update on my BFS3...
Last Friday, I took my carbine (home built with WW chrome lined 14.5" 1:9 4150 button rifled barrel with FSB, carbine length gas system, AIM Gen 3 Nitride bolt, standard buffer weight) and put 540 rounds of M193 through it (my reloads, TAC, Hornady 55gr, PMC once fired brass, 5.56 velocity) without it a single hiccup! 18 magazines (pmags and D&Hs) in less than 30 minutes all as dumps or quick doubles without a single FTF, FTE, anything... I could not out run the BFS3 as hard as I tried. Absolutely awesome. I'm hooked! - AG |

Coupled with a bumpfire stock. How fast can you go through a case of Wolf FMJ?

I have a echo in my LWRCI piston rifle and it's been good for about 1k rounds. I did have to modify the BCG but it's been great shooter.

Your chamber will heat up and your Wolf will start to sieze, requiring a hammer and a rod to clear. After that happened to me, cases of Wolf went very fast.............on backpage. I sold 5. Go ahead and ignore this advice. |

Is it controllable?
FA M4s don't seem too bad to control But pulling the trigger that fast looks like it would be unstable |

At short range (10-15 yds) I can dump a full mag mostly in the A zone of a USPS target with my AR9 and the ECHO. The double taps are what really makes the triggers valuable for defense imo. It's like having a burst pack on your AR. It's controllable and the semi trigger is sweet too View Quote |

Still not sure if its worth 475 bucks Maybe when prices lower |

my BFS Gen3 worked fine with my 14.5" 5.56 mid-length Adams Arms piston conversion. Spikes T2 buffer and standard M4 CS buffer spring. no hammer follow on the mag dump.
(going back to the OP question about piston AR's) incidentally, street price on the BFS3 (e.g. GB) seems to be about $375. |

That makes sense...2 rd burst like the CZ 805 Bren. and a good SA trigger too Just thought the FA rate was a bit of a gimmick. Still not sure if its worth 475 bucks Maybe when prices lower View Quote |

Anyone have any information on the Evello Mortem EM88 DT ??
Their website says shipping in three weeks but I think it has said that for a while. There are only two videos on Youtube. I'd like to know more about this system and how it works? T2 |

Most forums call these triggers bad names and dismiss them. The videos on the Fos-Tech look impressive to me. I don't mean the mag-dump part, I mean the control the shooter has of each shot while shooting fast---totally unlike full auto. The other impressive thing are the double taps. The shooters on the videos report increased accuracy and of course it comes very fast. So double tap, double tap, double tap, aiming and controlled all the time---how do you go wrong here? The safety can be employed from any firing position, anytime. The semi-auto setting has a double stage trigger. What is not to like except the price?
