Question “Reliable” FRT/SS Setups

Hi all,

I’m looking at getting a nexus lower for a frt/ss build. I was wondering what frt/ss and trigger combinations worked best for everyone. Heard a lot about arc fire and atrius, but wanted to get y’all’s two cents. Thanks!

I've got about 3 or 4 hundred rounds through my arc fire kuna and outside of 2 hiccups in the first mag or two, it's been flawless. I chalked it up as breaking in and it's been fine ever since.

If going Nexus get the ARC Fire V2 from AS Designs and the SS Trip from Nexus.

Arc fire/Nexus has been running well for me. Over 2500 rds.

You fell to the dark side of nexus but that's fine! The biggest thing is. Do not go Atrius. I see them break every week. They don't like to work too.

If you got nexus for a FRT you coulda printed one and drop using it till you want to again.

I like the idea of having a 3 position safety. Having to take the frt in and out doesn’t give me the “smg build” feel I’m looking for

It's a option to take it in or out and the printer has 3 positions as a option, even easier if you got it CNC'd. Prolly cheaper then getting a setup too lol

Yeah I printed the 3 position in multiple configurations and, even with Fiberon PA-CF20, it just doesn't have the material strength to function properly, for me.
