Franklin Armory BFSIII BFS Gen3 Binary Firing Arrangement Trigger Review
On Independence day (2016), Franklin Armory released an updated version of their Binary Firing System; dubbed the BFSIII; also known every bit the BFS Gen3. While this is being referred to as the tertiary generation of this trigger, many of y'all may exist wondering what happened between the last BFS, and this one? Well, the "original" BFS we tested last year was actually the 2d generation of the BFS, which we'll be referring to as the Gen2 in this article. The offset generation of the Binary Firing System was never released to the public, with only a prototype drawing existence displayed at SHOT Show 2015. Later on some suggested changes from BATFE, Franklin adult and released the BFS, aka the Gen2.
See our YouTube video review hither:
Franklin Arsenal was kind enough to send us a pre-production sample of the Gen3 prior to its launch on July fourth. This unit was pretty much identical to the full production models they are aircraft at present, save that our pre-production trigger lacked whatever type of finish on the disconnector and IDS. I dropped the unit into my brand new Daniel Defense DDM4v11 rifle, and hit the range. The results were impressive from the start, with the most noticeable deviation in performance being the trigger'southward pull weight; we'll become into that more later. Subsequently about a week with the pre-production model, we sent it out to the next media outlet, and patiently waited for our full production sample to arrive.
The original shipment date was gear up for early on to mid August, which Franklin held pretty close to, starting shipments past the terminate of the calendar month. Unlike some companies out there, Franklin was open up and upfront nigh any and all delays, and they worked tirelessly to get the Gen3 trigger out as fast equally possible. Nosotros received ours in the beginning week of September, and tore open the box like a child at Christmas! Inside was the BFSIII trigger components, forth with two sets of trigger/hammer springs, an extra IDS bound, and their extra power carbine buffer spring.
Improvements over the Gen2 BFS:
- A simpler design that is non restricted by existing drop-in AR-15 trigger patents
- Easier to install (no shimming of the trigger pack or machining of your lower required)
- A lighter total pull weight of approx. 4.5 LBS (+/- .5 LBS)
- Uses a standard hammer, making it uniform in just well-nigh any rifle that uses a standard AR-15 fire control grouping (.308AR/AR10, Sig MCX/MPX, blowback ARs, etc.)
- No BUD (aka Back Up Disconnector)
- Lower pricing than the competition ($429.99 MSRP)
Close up look
BFSIII kit as received from Franklin.
Above you can see the BFSIII kit, which includes: BFS trigger assembly ( Intermittent Disconnector Spacer, disconnector, disconnector spring, and the IDS spring captured by a dummy pin), the trigger spacers, standard semi-auto hammer, Franklin'southward Ambidextrous prophylactic selector with ane short and ane long paddle and paddle screws, 2 mil-spec trigger pins, 2 sets of trigger/hammer springs (standard mil-spec + lighter ready to suit pull weight), a spare IDS spring, a sticker with safety selector markings, and finally their extra power carbine buffer jump.
Install
Ane of the key benefits of the Gen3 over the Gen2 is easier installation. Due to its simpler design, the Gen3 BFS drops in much easier, and requires very few boosted steps over a standard fire control group install. The but expanse where you need to be careful when installing this trigger is when inserting the trigger pin. Franklin has a slave or dummer pin installed in the trigger assembly prior to aircraft, which captures the IDS spring. When you insert the trigger pin, they recommend inserting it from the right hand side of the lower, using the hammer pin on the left side to guide the slave pin and keep everything lined up. This ensures the trigger spacers on both sides of the trigger are lined upwards properly, so the trigger pivot and slave pin can move easily.
I did come across a little chip of resistance when installing mine, which ended upward requiring me to push down on the back of the disconector to allow the IDS to slide back. Be sure to scout our in-depth trigger install and function check video earlier you install yours. Franklin does include a very detailed set of installation instructions, however sometimes it's easier to watch someone else do information technology, earlier attempting it yourself (I do that all the time, thank God for YouTube).
Lookout our BFSIII install video here:
One time installed, we highly recommend y'all run through Franklin'due south detailed part checklist. This will non only ensure the BFSIII is operating properly for the all-time performance, but it also ensures that its safety functions are working properly.
I installed the Gen3 BFS into 2 lowers while testing this trigger. The first was my Daniel Defense DDM4v11 lower, which can be seen in our install video in a higher place. The next was my Colt LE6920 lower. The reasoning for swapping information technology into the Colt was to prove many of y'all that it drops correct in, different the Gen2 which could take required the lower to exist machined in society for it to fit.
As you lot can encounter from the summit view, the BFSIII fits perfectly, with the Colt sear web is still intact.
Performance
I tested the BFS with various DI gas system rifles, from carbine through burglarize length. The first affair that impressed me about the Gen3 was that it required much less tuning to prevent hammer follow. Now, I want to be completely upfront and tell you that hammer follow is still possible. Considering the BFS triggers do not have an added sear trip to control timing, there is no real way to eliminate information technology without tuning your rifle a chip. Thankfully, the Gen3 seems to run much more reliably with a wider range of platforms. Many users are reporting that it runs not bad in their 5.56, .300BLK, and even 9mm ARs with no changes. I personally didn't meet that "out of box" 100% functionality, but I didn't have to change a agglomeration of parts either.
One matter to remember virtually tuning the BFS is that it's very dependent on ii things: one is your rifle, 2 is your finger. If you can move your finger very apace, information technology'southward possible you'll have a higher chance of experiencing hammer follow. That said, it all depends on your rifle. Every bit I stated earlier, I did not run into 100% function with my rifles right out of the box. I did see very good operation, but I was still getting hammer follow ever other magazine or so. Because I've been playing with these BFS triggers for quite some fourth dimension now, with close to 5000 rounds over them, I can become my finger going pretty fast.
When I got the pre-production BFSIII in for a quick exam for the launch of the trigger, all I needed to get 100% office was a SpringCo Red Extra Power buffer spring (carbine). This was with the trigger installed in a Daniel Defense mid-length burglarize. However, when I got my full production trigger in later this summertime, I found that the heavier spring (whether using the included ane from Franklin or my SpringCo) did not assist reduce hammer follow in my rifles. Neither did swapping in lighter or heavier buffers (I tested carbine through H2).
Because of my by feel with the Gen2, I had brought quite a few parts with me to the range; from lighter and stronger carbine buffer springs, to lighter bolt carriers. In the end, all my rifles needed to run 100% was a lighter bolt carrier. This was the case with both carbine and mid-length gassed rifles, nonetheless not the case with my burglarize-length upper, which uses a Faxon Firearms 18″ GUNNER barrel. The xviii″ upper actually ran the all-time with a standard M16 carrier. Below are the setups I used with each to become 100% role. Annotation that each setup was used with a lower configured in carbine format. I did not get to test the BFS with an A2 setup. As well, notation that your mileage may vary. What works for me may non work for y'all and your rifle.
Volition'southward setups for 100% function:
- Carbine gas: stock carbine buffer spring, "H" buffer, AIM Lightweight Commodities Carrier
- Mid-length gas: stock carbine buffer spring, "H" buffer, AIM Lightweight Bolt Carrier
- Burglarize-length gas: stock carbine leap, "H" buffer, stock M16 style Bolt Carrier
- Ammo used with all three setups was a mix of Winchester 55gr Q3131, Wold Aureate 55gr .223, GECO 55gr v.56, and ZQI SS109 (M855 clone)
Terminal Thoughts
Franklin Armory continues to lead the way in the Binary trigger marketplace. The refinements and improvements we accept seen with the Gen3 are much appreciated, with the spotlight falling on its improved reliability and trigger pull. The pull weight has been reduced significantly compared to its predecessor, offering a much more pleasing trigger when using the BFS in Semi mode. Our trigger's total pull weight was right in line with Franklin's claim of 4.5LBS (+/- .5LBS), offering a prissy break and reset.
With a MSPR of $429.99, some will say these triggers are overpriced. However, I feel that it's a great bargain for the functionality your are receiving. With some practice, and possibly some slight tuning, you tin reach faux total-automobile fire at circadian rates that match the M16. Basically, if you're into doing mag dumps, this is the trigger you seek. If yous're wanting something for faster controlled pairs, the BFS has you covered at that place as well.
For those of you asking, "would y'all use this trigger to hunt with your AR?" The reply is aye. In semi way, the pause is light enough to use for hunting, peculiarly mid-sized game. For varmints, I'd prefer a two-stage trigger though. Binary mode might as well show useful when hunting hogs or predators, where a fast double might assistance ensure a quick and efficient kill.
