Hi all,
I was just wondering if anyone had tried using a Franklin Arms Binary trigger in a KS47 (pistol or carbine)…
A binary trigger should work fine in the KS47.
what is the SKU# so I know the one to purchase for the KS 47
Should be the BFSIII AR-S1 for the straight trigger, BFSIII AR-C1 for curved.
Finally tested my KS-47 with the binary trigger. It worked perfectly - with one exception that was not the trigger’s fault (will describe below). It ran great, and was GREAT FUN to shoot.
Only issue… With the binary trigger in binary mode ripping off 2-3 rounds per second, my 75 round Korean drum mag kept falling out of the rifle - unless I held the mag release lever. Yes, I know how to install a “rock and lock” AK mag. They were correctly locked in, 100%, but they fell out anyway. Why?? I think the weight of the drum mag, combined with the cyclic rate of the binary trigger, caused the mag to oscillate back and forth and “walk out” of being locked. If I held the mag release lever, it stayed in just fine. Using 30 round PMAG’s it worked perfectly without holding the lever.
Some tips… 1) Leave the buffer spring alone. Don’t use the Franklin Armory buffer springs that come with the kit. The KS-47 is beefier spring than either of the FA springs. You want the heavy spring slowing down that BCG. 2) Don’t use the Franklin Armory HAMMER springs. Move your stock KS-47 heavy hammer spring over to the Franklin FCG and keep that heavy hammer spring for the hard Berdan primers. Yes, the trigger pull will be heavier than FA’s springs. But trust me, in binary mode you aren’t noticing the trigger pull weight being heavier. You are focused on just trying to aim the beast!!
