It looks like a medical injection gun šŸ˜‚ I hopped on the bandwagon after having a mark3 22/45 lite I decided to build this new member of the family out. It will be run suppressed 100% of the time with only subsonic rounds to help keep it clean. Yesterday I installed the Volquartsen competition kit and bolt/spring upgrade. With the upgraded rod/spring kit and internals, itā€™s tuned to run subs/suppressed and oh man such a nice trigger compared to the factory!! Super excited to take out it this weekend.

Thatā€™s a nice suppressor setup! Which can are you going to use?
 
Iā€™ve got one in stainless. With the can on it fits in a specific holster.
 
I have a big collection on MKII guns.
Have been wanting to do a short one threaded for some time now just never got around to it.
Have a factory none threaded MKII with 3'' barrel if I recall.
 
Cut mine to 4 in. No can. Runs all the lr perfect. I assumed less than 4 in and I'd need more changes for reliability.


I didn't buy new internals. Just modified the mag lock out to function like the expensive blast shield thingy so it runs mag out. Converted the mags to 11 rounds and polished the factory sear. Added a dot to the factory front sight.

Thatā€™s still up in the air. I was thinking about the surefire ryder but then took a look at the rugged mustang, but after watching a dead air video where they compared a couple, it made me indecisive. Iā€™m trying to keep the diameter small to keep a streamline look. Any suggestions would be great

Does the bullet stabilize?

Short answer yes

Long answer: This past weekend I was shooting at some steel targets mainly just to test for function to make sure the proper springing of the newly installed parts were copacetic.150 rounds and not a single hiccup, and I did a comparison it sounds just as quiet as my MK3 22/45 lite with its normal length barrel. I would have to say that it stabilizes enough bc there werenā€™t any baffle strikes the red dot was not cited in so I couldnā€™t really do anything past 20 feet but the groups were nice. Iā€™ll take it to the wake county range tonight and see what it can really do. Iā€™ll keep an eye out for what the bullet holes look like on paper if theyā€™re keyholingā€¦ but I was just happy to not have any failure feeds, failure to eject, stove pipes or short strokes so thatā€™s a win in my book. Now I just need to get the suppressor choice down. It just stinks that I have this newly built toy and Iā€™ll have to wait 270 days for the suppressor. Well, at least thatā€™s how long it took for my rugged obsidian 9 to clear.

The mini mamba is perfect!! I was seriously contemplating that. I just like the rounded classic look. I do wish that the new MK4 had a barrel that was the same diameter is the receiver so the suppressor wouldā€™ve mated up perfectly like it does on the Lite. But the lite canā€™t be cut down according to the gunsmiths I guess because itā€™s a fake bull barrel set up
 
Thanks, I'll appreciate your feedback on keyholing.

I bought a Ruger Mk3 I think with two uppers and the "mini" upper keyholes. I'm not sure if that's specific to the particular round I was shooting or what. I too had no baffle strikes but at about 20' the holes were oblong.
 
Thatā€™s the first thing the gun smith cautioned me about was having the barrel under 2.5inch would present a keyhole problem,I built this gun strictly out of novelty to be cool, quiet and to be reliable/function. Just a fun shooter for everyone

I have a Thunder Beast Takedown 22 In jail. I compared the Dead Air, Silencerco, and Thunder Beast. I donā€™t think you could go wrong with either of them.

First thing I thought seeing that was "New and Improved Deer Gun by CIA".

If your going to run it suppressed the volquartsen dlc bolt is nice too. I bought a blem mk4 bolt off eBay for mine.

Very smart move. There was another forum where someone had built a poly80 gun and immediately put on a suppressor and couldn't get it to consistently run. There were many people who noted that it would be best to make sure the gun ran well before adding a suppressor (I don't think he liked the advice).

I know it's not apples to apples to this post, but I think it's worth the time to fire the gun and a few ammo choices (especially .22s which are ammo picky) before adding a suppressor to the mix.
 
Really want to cut one of mine down like this, since trying slackers.
 
I also cut mine down really short and found there isnā€™t enough pressure to blow back without the can. I cut another one down to 2ā€ and it mostly shoots without the can. Iā€™m still working on tuning that one.

Help me out on this. So the logic here is that subsonic ammo will contain less powder and therefore burn cleaner/eject less crap from the muzzle? Do you know this to be true?

I'd be worried that combination of barrel length and subsonic ammo could not only have difficulty cycling and/or stabilizing (you covered those issues) but the velocity being so low having to hold over shooting just 25yds, lol.

Yeah I was doing just fine til you brought up the clarification questions. Now I am confused.

Normally I would disregard all that, but now that these days there is such a profusion of "Subsonic .22" ammo I presume that everyone is describing factory-designed (and advertised as) subsonic ammo.

But since we are talking sub 3 inch barrels here, which have a hard time even keeping Stingers supersonic, if ya'll wanted to be a little more specific with what you mean by -sub-sonic- (by design vs by default in short barrels) I wouldn't complain.

The trade-off is you blacken the can with all the excess powder

from my experience, I use a 3 inch barrel to make supersonic ammo subsonic. this way you can run cheap bulk ammo without having to buy the more expensive subsonic ammo.

Excellent, that's the kind of clarification I was looking for.

So in your experience, have you come across any bulk pack ammo that goes supersonic, or just loud trans-sonic with the 3 inch barrel? Or do they all stay under?

I know I never had any issues with a Beretta 21A (nothing going Super out of it) but with longer barrels, like 5inches and up I have had to be careful (which I hate, as that usually translates into more expensive per round) because, depending on the temp and Extreme Spread, often there will be some significantly louder (like nearly as loud as a crack) rounds that spoil my trust in that particular round.

Barrel lengths between a Bobcat and say a Kel-Tec CP33 I haven't had much experience running bulk pack stuff with.
 
When I got my can originally I tried from 16ā€ to 1.5ā€ and found that 3-4ā€ performed the best for bulk 22 ammo. Anything less and it had gas pressure problems and longer was much louder.
 
Silencershop now has a Ruger exclusive mark IV model. similar idea. Personally I just run CCI standard velocity and a standard barrel length. Iā€™m not willing to give up the sight radius. But itā€™s a cool idea nonetheless.

I actually saw them for the first time at Blackstone in Charlotte a couple of weeks ago, which is why I thought this thread was so interesting since the OP and others have obviously building their own versions of this presumably well before they were being offered for sale on retail market. Of course Blackstone has a Silencershop NFA kiosk on site which is perhaps why Blackstone has them in stock.

You guys are ahead of the curve! True enthusiasts!

Makes me think of the time years ago when I walked into my local shop and saw a Ruger Charger for the first time. Everyone was crowded around "Ooooing" and "Ahhhing", remarking on how neat the concept was.

I was like "what's the big deal guys? I've had one of those for years". Amateurs.
