Is there anything out there that discusses measured ROF with different platforms/components with 9mm? An AR9 sounds promising, but the videos I've seen look like the ROF is very high and the vibration will knock my fillings out lol.

I started this morning posting ROF numbers for all the people who post SS videos. https://www.reddit.com/r/supersafety/

I tried a SkoPrints AK-47 FRT today on my old Romanian AK. It's an odd system, not like the RB or SS at all. I was not expecting much, in fact I was expecting failure, but I was amazed that it worked the first time I used it. I ran 4 30 round mags through it. You can feel the trigger being pushed forward but like the AR-15 it's not bad. For the money saved over a full auto AK I'll take it. I got a Taurus TX22 on order through my dealer as well. This FRT thing is a game changer.

Did Sko take forever to ship? I found them really bad. No reply to emails and months of waiting. Apparently I’m not the only one

I’m glad it worked! I put an AK FRT in a Mak-90. It took some work but it runs really well now.

I got it more or less right away. That was a few months ago. I just recently got around to getting the appropriate trigger to go with it. Communication is non-existent but they have a decent tutorial so I printed that out and followed it. I was completely expecting to have to go back and forth several times like I did with the Super Safety but it ran the first time.

Has anyone tried an Atrius rotating FRT/SS? Work well? Easy to get set up/adjust?

There seems to be some fake sites out there, which one is the real one?

 

[skoda]

I tried my CMMG unit with the BB trip and it doesn't quite have enough umph to recock the hammer. It does work without the trip in place. With the trip and the bolt weight it doesn't do much at all, it seems that the weight is adding a lot of drag to the bolt. Any suggestions on what to do? It seems that people are increasing spring weights but that's not going to work for me. I had to take the forward assist out because that was catching on the added weight and keeping the bolt from going all the way back.

I'd appreciate any suggestions because it's not making sense to me.

This is the real one. https://atrius.dev/products/

I was not impressed by the design. It looked flimsy. Reports of broken ones got out in a week of shipping.

I have no experience with either, just read the internet

What is the weight of your antibounce weight?

Are you running the chamber insert or dedicated barrel with collar?

What ammo?

 

[skoda]

I started with the stainless weight with steel rods at 674 grains or 1.54 ounces.

I have the chamber insert unit.

I tried CCI Mini Mag 40 grain round nose because that's what everyone including CMMG suggested.

Like I said, it runs fine in the standard semi mode but won't cock the hammer with the trip added. It also will not cock it with the weight (no trip) in it.

I bought the BB 'Tuner's kit' so I have other weights and springs to try. But that it won't fully cycle with the trip confuses me.

I hate to say it...but my experience with the chamber insert with a FA M16 was a frustrating failure.
I eventually bought a dedicated barrel and collar and all my problems went away.

I THINK I installed a lighter hammer spring too. Double edged sword though; it's generally believed that you need full power hammer springs for .22LR. I'm not convinced though.

 

[skoda]

Besides the obvious physical things what is the difference between the two systems? Does one get a better recoil impulse to the bolt? Does gas leak more on the chamber insert?

Think I'll try a lighter hammer spring, thanks for the thought.

Super Safe 249S SAW. ROF 557 RPM. Nice. An open bolt would be better, but pickers and all.

I got the FFT for the TX22 and it runs 100%, and it’s stupid fast. I’m 2/3 on getting the SS to work. The working 2 are in a Ks-47 and another in a standard AR lower with a Cmmg 5.7 upper. Both of these are also a ton of fun, especially in these 2 calibers. The frustrating SS is with .22 uppers..

If you haven't seen it, BoreBuddy has a video demonstrating bolt bounce and the efficacy of their weight to minimize it.

I think the simple answer is that when you lock in the bolt assembly to the barrel then most of the issues are eliminated; light strikes, directing all spring energy in one direction instead of moving parts simultaneously forward and rearward.....

I spent many, many hours and thousands of rounds of all types of .22LR ammo trying to get my FA to run decently with the chamber insert. I tried all types of magazine / ammo combos, even had the nice folks at CMMG custom bend several trips to see if timing was an issue. Nothing worked.

At their suggestion, I bought a dedicated barrel and the matching collar and everything just worked.

At one point I was researching a cure for this that involved drilling a hole in the receiver and bolt and installing a spring loaded ball detent that at the moment of hammer release would have locked in the bolt. I chose not to reinvent the wheel, but the lesson here is that this is a known issue and has been for a long time.

Hmm, not to be a pest or doubt you but the chamber insert is attached to the bolt assembly but of course the bolt itself can move within the bolt assembly. The chamber insert is the first couple inches of the barrel.

I've seen the bolt bounce video and got the tuners kit with all kinds of weight combinations but I need to get the trip working before I can play with weights much. Like I said, I wasn't getting full bolt travel with the trip or with the weight. I found a lighter hammer spring in my parts box. I'll try that first.

I found the CMMG barrel with the attached bolt assembly piece. I might have to buy that next. This "cheap shooting" super safety is costing me a lot!!!!

 

[ScottinTexas]

Without the collar and detent I was getting light strikes / failure to ignite…and lots of jams due to failure to eject and or clear the upper receiver.

It is possible to assemble the bolt, trip and weight incorrectly….I managed to do that one day at the range during a particularly frustrating day. I think I had the weight too far to the rear. Probably not your issue though.

My opinion is that in semiauto the insert design is fine, but in a FA / super safety gun the collar is mandatory.

I think something else is going on with your setup aside from the chamber insert. I have a 10 inch barrel with the same setup as you and it runs like a Swiss watch. Do you have the adjustable trip? What lower are you using ? I have one lower where the ss doesn't go all the way back even though its supposed to be a low shelf. Is your trip or rails of the cmmg kit warped at all ? Are you using a pressure plug ?
