Semi fun switch - Franklin Armory BFSIII HK-C1 Trigger - Binary Firing System for HK 91/93/MP5

Purchased this item for my clone MP5. Wanted to have more fun shooting than your typical semi auto. Have purchased Franklin Binary triggers for other guns and it makes for a fun time at the range. If you’re on the side lines of purchasing this trigger…don’t be. It’s a lot of fun….the legal way.

The trigger has three stages. Safe, semi auto and binary. It’s pretty straight forward and is the easiest trigger to install of all the Franklin Armory triggers. Just take apart the mp5 and drop it in.

Depending on your mp5 you have, you might have to adjust the extractor. This was my only issue I had after a few hundred rounds fired. If you get failure to feed or double feed, this is more than likely your issue. Just adjust the extractor and you should be good to go. Stick with 124gr fmj ammo also. The Binary trigger and firearm does very well with it.

Only down side I would say is the price! Try and get it on sale. I think The price is extremely over priced. If money is no issue though, go for it!
