CAA GEAR Micro Roni Stabilizer: Suppressor Host Mod

[CDR_Glock]

Recently, I wanted to modify the CAA Gear Roni Micro Stabilizer for Suppressor use.

The opening of the enclosure was too narrow for a Can on a standard Glock 19.

I have seen people cut the plastic opening. Not something I wanted to do.

Thanks to Solscud a Youtuber and reviewer, and LOS from AR15DotCom suggesting some mods, I did what I did.

I acquired a 10” threaded barrel from YRS, Inc, by IGB Austria. It protrudes beyond the Roni frame for my Suppressor.

In summary, I tried different brands of ammo, but the Roni as it stood, was not working with the suppressor. I was getting FTE after FTE. It was OK without a can (limited test of 10 with 1 FTE)...

I initially changed the Guide rods and spring, thinking the higher power spring was creating resistance causing the FTE. I saw a YouTube video of someone with a 16” using the mod which appeared to work. But again, FTE after FTE so back to the drawing board.

I ended up cutting the Concussion device as was suggested, as the barrel was contacting it. I could see a small segment of wear on the top margin of the barrel.







You see the rub point on the dorsal barrel margin.





I took off the excess steel, but questions were raised if the barrel would still contact the concussion device.







It was not pretty, either.





I mounted it onto my Bench vise and I let the dremel have its way. Because of the protruding end of the Concussion device I was just going to cut it first, then trim the edges.








I sanded and polished the near finished piece.








The daunting task of reassembly was intimidating.





Because the rail screws did not loosen I did not bother removing them.


I placed the detent spring of the rail release and pushed the parts together, and I hammered with a plastic mallet.








The rest was easy





I now have clearance for the barrel.








So I went from this:

Did you try it again yet?

We have had very poor success with the Micro Roni and suppressors. I recommend the Mechtech uppers when people ask about suppressed Glock carbines. Not much more expensive and turn the gun into fixed barrel straight blowback, which doesn't care about suppressor weight or backpressure

I just did the work last night. I’m going to try it after work today.

It worked apart from the slide not returning to battery by a few mm. I have 13# springs in it. I think I’ll go back to factory springs and try again, tomorrow.

Well, I cut it down to this.


I still had some failures to eject. I used Lawman 147 grain, Brass.


I had 4 shots work in a row, though, right from the start.


Then I had 2 in a row, followed by 3.


It didn’t feed aluminum cases, though. Blazer Brass 147 grain.


It had FTE for PMC 115 gr Brass...

After that trial, I had to rethink what to do.


So, I did the following:


I used a Dremel to open the port of the Roni, and I also widened the Concussion device or aluminum muzzle of the enclosure.


I cleaned the suppressor using my ultrasonic cleaned, and I used lithium grease/Teflon.


I lubricated the Glock, and I used a 15# recoil spring.

As an update I tried a couple of different rounds of ammo. Fiocchi 158 gr and Lawman 147 gr.

My friend shot it in the video.

The sound of Fiocchi from a 10” barrel is much quieter than a 147 gr.

I did do a rapid fire 10 round run but I didn’t record it, unfortunately. It did run without an issue.

I have not seen an IMI Kidon Suppressed, so I will try my hand at making it work.

As for an actual PDW, I’m going to do a CZ SCORPION.

What if you had used the 7" Glock barrel from YRS IGB for the Mod on the MCK? I will have to mod the barrel shroud for the 7" on my G17 to fit but will I have a problem w/ the cycle?? Thanks for your thoughts.

 

[CDR_Glock]

I just saw your question. I still think you’d have to fiddle with the shroud
