It passed all its checks.

16” mid gas FSB, Atrius, rise 140 h2 carbine spring

So, is it gonna work, blow up or need more spring?

I don't have any experience with Rise triggers but in my experience with other FRTs you will need a heaver buffer.
I don't need therapy. I just need someone to rob me at the gas station so I can let it all out.

There's a good chance it will work.

More spring is not automatically a good thing with FRTs. They increase bolt speed, which exacerbates bolt (carrier) bounce. Only use as much spring as you need.

Your H2 might work, might not. Go shoot it to find out. Make sure it's a real H2, with three sliding weights, two of them tungsten and one steel in an aluminum body.

When was your Rise trigger made?

Rise 140 and Cornfires - I have 2 - soon three. The first 2 have H3 buffers and fun fine.  Plan to use another H3 from Tony for the buffer

You rarely if ever want more spring. Heavier spring = bolt bounce.

You would be surprised at how many setups work with just an H buffer.

I have seen a plain old carbine buffer work 100% with a Super Safety even.  

So I bet yours will work.

It's obviously not a direct quote. I'll add more emojis next time.

I've been told repeatedly that the odin heavy will not function as an FRT buffer. I have seen it posted here, reddit, etc. I can appreciate that you notice trends (I believe this), but not everyone is as reserved with their conclusions.

In 5.56? Blows my mind haha. I haven't had any issues...but I really want some of those DBCs to try to run in the SCW style/sbpdw braces with the short buffers. I *think* it should allow them to run without bounce...that DBC is very cool. And if I do run into issues, that Tromix seems to take care of it.

Funny that you mentioned Odin.

I just got in one of their buffers. If I can get up early enough tomorrow morning to beat the sun up I'm going to try it out in several different rifles in different configurations (Gas systems, FRT triggers, etc.).

The one on the left is newer, and it works with the Atrius. The one on the right is older, and doesn't pass the standard function test. Both are Rave 140 triggers.

Have you seen a 140 with a SS cut? I have one and I don’t know where the hell it came from. The rear of the trigger bar is cut (right side cut). It doesn’t have the rave 140 markings my other does but it looks like the same trigger. No springs. I thought maybe I should pick up an Atrius for it…but they usually run with an uncut 140 yeah? feels pretty silly to have a clearly FRT-cut trigger and have no idea what it is for…but here I am.

@BKenton I dont think its a Rise brand trigger. The housing and the hammer arent right for a 140. It should work with an arcfire or a ss , but not an atrius

Thanks for the input. I’m sure you are correct. I’ll have to wait on trying it out, I’ve got Gisselles in my arc-fires, and I don’t have a normal SS.

I don’t suppose AS is going to sell the safety/SS lever part separately from the trigger…but of a bummer having these cut triggers laying around.

So, I had a chance to shoot this in several guns. It didn't create any problems and did solve problems where the 3-ounce buffer wasn't enough.

One thing I tried that was a failure for me was the Odin Heavy Adjustable Carbine Buffer. I thought having a buffer I could change and test with would be great, but I could set it as the same weight as one I had that was working and it would create problems, put the original in and the rifle would run fine. Anyone have this issue?

I have several AZR 3pos, A Triggered Company Disrupter, an AS Designs ARC Fire with a Geissele SSA... and a FRT-15L30 from a company who's name should not be spoken.

The AZR 3Pos will run great in a mill spec rifle. A 20" A2 is just install and shoot it. Shorter barrels with less dwell times need a heaver buffer. Greate price on this one. It will not work in the Colts I have and the upper need to be cut to mill spec. This one seems bullet proof and my impression is that it would be the most durable.

The disrupter runs fine in FRT but its trigger really kind of sucks. Gritty and will even stick half way it you let off before the brake. Possible shooting it more would help.

The AS Designs Arc Fire & Geissele SSA trigger runs like a scalded cat and is of course great at single shots.

The FRT-15L3 is a good trigger and works fine but it has trigger slap and is expensive and a mill spec selector is $35 extra.

I have a Atrius (G-Lever) on the way to try out... I expect it will run like the AS Designs. They look very similar if not exactly the same.

The Atrius…looks similar to the AS. It really is a significant step down in pretty much every respect. It has a thinner less substantial lever, requires a spring to move the SS lever around…the AS is pretty obviously a much more robust and more intelligent design.

Atrius ran well in my carbine. H2 buffer felt pretty smooth, but still ejection at 2 o’clock. Had 1 light strike, but that was 1 in 150. So, I think I need to try the blue spring before the H3. Your thoughts?

Extra power springs make carrier bounce worse. H3 buffers make carrier bounce better. Go with the H3, if it's cycling then you do not need an extra power buffer spring.

Well, I received the Atrius, installed it and it was dead trigger in semi unless you moved the safety back just a bit past the detent, then it would fire.

Looks like the detent pocket was machined a bit out of alignment. It also didn't "feel" as good in semi, like it was interfering with the G$ trigger from operating correctly. Didn't have this problem with the AS.

Requested a return.
