Franklin Armory BFSIII HK-C1 - Trigger Group For  MP5 .40/10mm- Universal Housing

Our new universal binary trigger group will come set up as a MP5 40/10, but with our Navy 3 position universal housing you will be able to install in a MP5/SP5, HK 93, HK91 or clones just with the simple swap of the ejector lever. Our housings have been clipped and pin to accept any style  receivers that are in spec. This is the best option for those that have multiple receiver. A quick and simple swap that takes less then 5 minutes to accomplish.

This binary trigger group will come completely assembled and ready to drop in on your MP5 40/10. Our upgraded aluminum selector levers are anodized and lasered engraved for quick identification of current position. Our selector lever lines up much better than other selector levers on the market made with 6061 aluminum for a more durable and resistant lever. Only the best levers for these complete trigger groups.

Limited quantity available, once they are all gone there will be no more! 

Includes:

  • Franklin Armory BFSIII HK-C1 trigger pack
  • HK German - 3 Position pictogram housing - bolt hold Open cut out on housing for clearance for receiver.

In position 3 it will fire 1 round on pull and 1 round on release. This makes it the fastest semi-automatic trigger on the market.The BFSIII is ideal for tactical and competition use. The BFSIII provides greatly reduced split times between rounds and the ability to place two separate shots into a tighter group.

Trigger Operation:

  • Position 1: Safe- Will not fire.
  • Position 2: Semi- Fires 1 round per pull.
  • Position 3: Binary- Fires 1 round on pull and 1 round on release.

Specifications:

For use on a 9mm caliber you will need to swap out  the correct 9mm ejector lever and hammer spring that is included in your packaging. This trigger group comes installed with the heavier spring that is intended to be use for 40/10, .223/5.56 and .308/7.62 calibers.

    Hkparts will have at your door in days, a ready to install giggle switch that costs 1/50 the cost of pre86 toys and none of the headache. The only downside is the dent it will put in your coveted supply of 9mm. Yes you can buy the kit and erector set your way into an allen wrench yielding frenzy.. or you can just click, wait, shoot and buy mode ammo.
