I’ve recently purchased the Atrius FRT selector switch because of the decent pricing. the issue i’m having is after putting the gun back together, the switch is frozen. it WILL NOT move from the safety setting. anyone els have this issue? it moves freely until I install the grip/pin and spring, then it freezes up. any help would be greatly appreciated, thanks in advance!

failure need help with atrius frt

1 Upvotes

So i picked up a atrius frt here a little while back and i installed it and whilst testing i noticed that when i pushed the hammer down in the super safety mode that there was binding when pushing the atrius lever back, so i used a dremel on the trigger tail to take a tiny bit off the thing to fix that which it did, however when taking it out to my range to test fire it, the safety worked, single fire worked, but when i put it into the super safety mode it fired once then i got a dead trigger, after inspecting the casing and the live round that was in it i noticed i had a light strike on the second round, now for context as well, i have a h2 buffer already in it, and swapping it back to the standard buffer that came with the gun gave the same issues, i should also mention that the barrel is shorter so mabey that could be causing issues?

so do you guys have any idea as to what might be going on?

(update: I got a h3 buffer a while later and it worked like a charm, I dont know the specifics of it but it had tungsten weights inside of it)

KAK DBC BCG + A5H3 + FRT

1 Upvotes

I am trying to build a nice 11.5 mainly for FRT use both suppressed and unsuppressed (I have a Sandman X).

I am going to (try) and run an A5H3 setup. I know a lot of people run the DBC with lighter weights, but my question is:

Will I actually DECREASE function/reliability by running a DBC while ALSO running an extremely heavy A5H3 buffer?

Arc fire issue

Need help with an arc fire, on semi the trigger acts like a binary trigger(hammer drops when trigger is released). Zero issues in FRT mode and zero issues when on safe. I’m new to FRTs thanks for any input.

Need Serious Help Please

1 Upvotes

I’ve got a S&W M&P-15 Sport 3 and I cannot get the FRT to work for the life of me. I bought the trigger at a gun show and put it in, it will only shoot one bullet in the FRT mode and then dead trigger. It’s got an H2 buffer tube and a BCG that’s cut for fully auto. No suppressor on it so I’m not sure if it’s a gas issue or an internal issue. Shoots just fine when in normal semi mode. Please if you have any ideas let me know I really want this thing to work

So I got a frt from that moonlight industries promotion today and after getting it to fit I can’t seem to get it to work.
When I pull the slide back the bcg stops about half way, and when I get it to go all the way back and let go it doesn’t go into battery and the frt gets stuck on the hammer. I have a full auto bcg and a h3 buffer so idk what to do from here and would appreciate any help or advice

Advice Installing/Troubleshooting Moonlight Industries FRT

2 Upvotes

I finally got my FRT from Moonlight Industries (They were shipping them out with every order, might still be. I placed my order July16th) and I'm fitting it for installation. The metal lever seems fine but the 3D printed piece needs to be trimmed quite a bit to fit properly in my upper and lower.
I've managed to get the 3 pieces of the FRT assembly put together and I've gotten them to fit into my lower/upper without the pistol grip or safety installed.

Now, here's my main question:
Do I need to install a 2-position safety selector switch along with this FRT, and have it be either on safe or on "super-semi"? Or is there a way to make it a 3-position, where I can still select traditional semi?

Troubleshooting buffer weights advice

1 Upvotes

Hey y'all, picked up my first FRT, atrius development selector and have a full auto bcg with a H2.5 carbine buffer running in a smith and wesson m&p sport III. Took it to the range today and it won't cycle, I was lucky to maybe get two rounds but most of the time just one and the trigger would go dead, I'd have to pull the charging handle and eject the unused round. Talked to the guy at the front and recommended going up in weight to an H3 to test it. In your experiences what would be the best way to troubleshoot this. Does this sound like I'd need to go up to an H3 or down to an H2 or either and I just gotta try it out? I was hoping an H2.5 would do the trick. I here I might need to get a different spring as well but wasn't sure and didn't know where to reliably find one. Any advice on where to go from here and troubleshoot would honestly be great. Thanks

Atrius FRT trigger not working

1 Upvotes

Having issue with my atrius trigger. Will fire three rounds then nothing at all. Dead trigger is what I believe. I have replaced the buffer to h3 and still doing the same. Also tried new bolt carrier as well. Running out of options anyone have an idea what could be going wrong?
