Super Safety Review

[strobro32]

5.56, 300 Blackout, GMR SS, H3 buffer
22 LR = RTB dedicated 9" barreled 22LR upper + RTB 22LR kit +GMR SS, BoreBuddy pressure plug, BoreBuddy adjustable SS trip and CMMG full auto solid stainless steel bolt weight. The BoreBuddy ambi 22LR charging handel is very nice too.

AS DESIGNS has a good trouble shooting guide now that GMR has taken down theirs.

Sell every other FRT maker's product.
The GMR SS does not bind bolt with heavy trigger pull like all the other FRTs.
No learning curve.
No focusing on the trigger when shooting.
3 POS.
Currently legal.
The only way to improve it would for the next gen to use a traditional rotational safety design in stead of push through cylinder.

Awesome!
I’d really like to try one of these.

 

[strobro32]

You really should.
Caution: Product may cause regrets about buying registered MGs.

 

[StenAtopia]

I agree!!!!

 

[StenAtopia]

Member “Haris1” should be here soon. He goes ABSOLUTELY NUTS over these things!!!!!

 

[strobro32]

He's going to regret spending $350+ on each of his other FRTs.

Unfortunately, FL has law against a device that increases the rate of fire. The problem is that it’s so vague, that you can easily say that replacing an AR-15 trigger with a fancy 3 gun trigger could violate the law.
I’m hoping someone will challenge it (GOA or another organization, one of them might be doing it). There’s really no teeth to it, as I’ve seen dozen of people with the FRT’s here and the law was to target bumpstocks. Naturally, they went way over board and made it to where it could encompass anything and everything.

 

[strobro32]

Sorry to hear that. I hope pro2A organizations jump on that.

I’m happy that I bought a RB FRT when they were first offered since those guys took the fight to the ATF for these.

The RB FRT is now surpassed exponentially by the SS.

 

[strobro32]

I'm happy I bought RB FRT too. I feel like I supported our freedom.

EDIT 4/19/25 Rare Breed -ABC LP, LLC has sent Cease and Desist letters to all the small SS metal makers claiming they own the rights of ALL forced reset trigger designs. The far superior SS design has very little in common with the FRT-15. I regret supporting RB. I will not do so in the future.

I did sell it after blowing through 2K rounds of 223 in a month or 2. I made my money back on the sale of the trigger but not the ammo.

I did need to remove some material from the top of the lever with a rotory tool, to keep the BCG from jamming. Then it ran flawlessly.

A better way to keep the bolt from binding during fuction testing is to remove a little bit of material from the back/bottom of some uppers. Details at AS Designs.com.

Another good resource for help is Reddit's r/supersafety section. Be sure to read back a 2 dozen posts to get the down low on what to expect.

Anyone know if the SS works with the CMMG Banshee 45 pistol? If it does, it may be time for me to buy it.

 

[root]

Nice think I'll buy one.

Also after looking at the site I really want one for my H&K SP5 but I'm not sure what all I need to make it run.
I'm guessing everything they have listed for the SP5.
Would that be correct?

 

[strobro32]

I'm not sure. I don't have one. I have not looked into that.

Interesting discovery if running a GMR 22LR super safety kit. It does not work for me when the buffer and spring are installed in a stock or brace.

The GMR 22LR kit uses their steel cam, their 3D printed lever and their 3D printed bolt trip. (did not try the additional GMR adjustable bolt weight) ** The Bore buddy also makes a metal super safety "adjustable" trip but it did not work with the steel GMR lever or the GRM 3D printed lever

I put a brace kit on the pistol AR22 with the 4.5" Ciener/CMMG/Borebuddy dedicated 22LR upper kit. I was using a lower receiver pistol plug and plate for the lower receiver. This is Spikes plug and it was not putting enough pressure on the CMMG BCG. I had to tape together 3 quarters on the plug to put pressure on the CMMG kit.

The GMR 22LR parts did not function when I added a brace kit. It would shoot 1 round and jam the next round 1/2 way in the chamber. I'm not sure why.

I removed the brace kit, reinstalled the plug and it functioned perfect.

Put the brace kit back on an it jammed like before.

Removed the buffer and spring from the tube and it functioned perfect.

Be sure to remove buffer and buffer spring from the tube if you are have function issues GMR 22LR kit.

I shot a CMMG Banshee MkG .45 ACP 5" pistol with a Super Safety this morning. Worked like a charm with a H3 buffer. I will need more than 13 round Glock 21 mags. KRISS 30 rd mags extensions ordered.

10 rounds, 751 RPM.

Thanks gonna go over it better but took a quick look.

Need to order the parts before they are EO'd out of existance.
Kinda gonna suck to replace genuine HK parts on a SP5.

 

[Deerhurst]

Thanks man. Just had to order a SS. You are costing me money!

Printing a debounce and trip setup for the CMMG 22LR right now.

 

[strobro32]

I used the steel GMR steel cam and lever and BB adjustable SS trip to make the dedicated 4.5" suppressed barrel Borebuddy upper 22LR function.

The GMR bolt weight would not function with any combination of W weights for the 4.5" barrel BoreBuddy dedicated upper. The OEM CMMG solid stainless FA bolt weight worked.

The GMR steel lever did not work with the BB 22 kit.

Edit: The plastic parts combo lasted less than 200 rounds.
