A special bcg is not needed. A select fire as in 3burst and full auto will require an auto bolt(m16/m4) style + tax stamp and extra paperwork. For just those type of triggers NO on binary. They seem interesting and would consider purchasing? I had 3 various tac-con triggers that work well. They don't fire on pull and release, just pull only. They were costly about 3 years ago. Not sure if produced any more?
That is the extra paperwork.
My research suggests pros and cons to both the FosTech Echo and Franklin/s binary.
Agreed. All we need is for some madman to use one in a mass shooting and they'll be outlawed. Just like what happened with the bump stops...
I want one because I like the idea of a mode of trigger engineering that exists between selective fire and semi auto, and relish how it annoys the ATF because it doesn't violate the letter of the law.
I have installed the fostech in customer guns, I do not like the new manual of arms. Things like having to hold the mechanism down to put it together and the stupid triangle selector. The install is also harder. The Franklin acts just like a normal AR, and the selectior acts like a normal AR
Have you ever installed a binary on a PDW? They look like they'd be the ultimate platform for one, in a real self defense situation they'd pack that two round burst in a trigger pull and release.
Yes, on my personal pdw
Nice! Did you have to change the buffer tube to make it run correctly? The Saint Edge BCG is M4/M16 isn't it?
No, the PDW uses a proprietary bolt that is similar the the Maxim Defense bolt. It is shorter than a standard AR bolt and the buffer fits inside the bolt carrier and lives in the upper, not the buffer tube. Thats why on the PDW you have to push both the take down pins to remove the whole upper to remove the bolt same as the Maxim PDX. Springfield and Maxim teamed up to release the PDW so the PDW and PDX share DNA. The PDX was originally designed to try to win the Socom PDW contract for personal defense weapons for the teir 1 community. there are plenty of videos of the little Maxim guns running full auto. So a double tab is no problem. Smaller bolt or not, It still travels the full length and cycles the same as any other AR. By the time you could even think about letting go of the trigger to let the second binary trigger action happen the gun itself has been back in battery waiting for the slow human to react.
With your Echo installations for customers were you replacing their buffer springs or were they running with out of the box buffer springs pretty well?
And it edit myself (I apologize for annoying you with so many questions), I meant did you put the Franklin Armory spring that comes with trigger in the PDW buffer, I accidentally said replace buffer tube, but I meant spring.
