Sub-Silent Suppressors | #1024 – Rossi Survival Take-Down Rifle .22lr rim-fire and .410 center-fire Combo – & Shooting Adventure

Note: At the bottom of this project page, is an update on my Rossi with Polymer Internals and Weaver rail mounted on over-barrel silencer. 

Update: My first shooting trip with the Rossi:

Rossi Take-Down - 11

Although having had my Rossi for many months, I had yet to take her shooting in the field. Last week an opportunity arose for me to have a couple of days away in my caravan up north. Parking the camper, I had time during the afternoon to drive around in my van and scope out the land, looking for a place to return and shoot in the evening. An old quarry looked ideal with a cleared field surrounded by native and pine forest.

Right: Some developments on my Rossi. Set up for remote video activation. 

Returning around 7pm, I unpacked the Rossi from its short padded bag, mounted the rim-fire barrel with 2-6×32 zoom scope, and filled a pocket with CB-Longs. If you haven’t tried these in your .22lr, I suggest you give them a try. However, they do not have the strength to cycle a semi, so are really only useful in a bolt or hammer action.

Loading a CB into the chamber, I began a slow and careful walk across the open field.

One thing I’ve learnt, is to take extra care and stealth when rounding a corner or the rise of a hill. Chances are, there will be some sort of small prey or varmint waiting undetected. Only twenty meters across the field and over a small running creek, I spotted a Pukeko strutting in the distance around twenty-five meters away. These are off season, but a good opportunity to practice my skills of approaching undetected. With a large Willow tree to my left, I carefully scanned the field in that direction. Staring straight at me through the spindly branches and new foliage, was a medium sized rabbit, and black to boot! It’s been said that black rabbits are around 1 in 100, so if you see one – chances are that another 100 ‘normal’ rabbits are somewhere nearby. Well, that’s the theory anyway.

Carefully I adjusted my scope to 10 meters, and around 4x zoom power, pulled back on the hammer, rested my finger on the trigger, lined the cross hairs on the rabbit’s chest, and squeezed the trigger. Being absolutely silent with my compact over-barrel suppressor, I instantly heard that dull ‘thud’ of impact, indicating a successfully placed and lethal delivery of the projectile – that we have all come to love and recognize. Bunny did the normal 20 second twitching as the nervous system recoiled from shock, and then lay still on the grass, with another larger brown hare running off at the speed of light!

There’s a little trick I have learnt to do, in order to ensure the prey is fully expired and in no pain. That is to take a small twig and touch the pupil of its eye. If there is any life, it will react. If not, all is at peace. Now, I have an affinity for cats, especially my own two – Moo Moo and Judas. Yeah, I know, strange name for a preacher’s cat. I reckon every church has its ‘Judas’, and at least this way I know who it is! Picking up the bunny, it was soft and warm, just like my cats, prompting me to appreciate the health and condition of this fine little rabbit.

Normally I am happy with just one kill for the night’s shoot, but as I had only been on the field for around eight minutes, I decided to head the way of the other hare that streaked away. Strolling through knee high gorse and grass, I was amazed at the Quail that would only fly away in panic when almost standing on top of them, making me think they are probably not used (or afraid) of humans at all.

Rounding another blind, there in its typical ‘freeze’ before sprinting away, was another large brown rabbit. Again, I pulled back the hammer, lined up the crosshairs between the sholder blades of the bunny (it was pointing away from me) and let another CB hit its target. This initial shot crippled the rabbit, but did not extinquish life instantly, calling for another quickly and precisely placed shot to do the business. Another fine rabbit, and a most successful evening’s shoot. Off now to the takeaways at Matakana, for some well deserved fish and chips. Next time I’m up this way, I’ll come back here again. One thing I know – is there is at least one fine hare ready and waiting.

And my Rossi? I am very pleased with this little rifle. It is super short, light and accurate. Being single shot is lots of fun, and ensures a careful and well planned shot. One thing I also learnt, is pulling out a pocket of coins to pay for dinner, gets a rather surprised look from the takeaway owner, when several bullets are thrown into the mix!

Complete Set-up:

  • Rossi compact take-down rifle, single shot
  • Interchangeable barrels: .22lr rim-fire and .410 center-fire
  • Both barrels threaded 1/2″ unf x 20 tpi
  • Custom thread protectors
  • Hammer side-ways extension
  • Raised stock cheek pad
  • Remington folding bipods
  • Custom rim-fire over-barrel suppressor, bored out for Bird-Shot
  • Custom center-fire over-barrel suppressor with ported shroud
  • Custom compact rim-fire over-barrel suppressor
  • Rim-Fire barrel taped for Weaver rail
  • 3-9 x 40 compact scope, mounted on rim-fire barrel

UPDATE: While I really like the longer over-barrel suppressor for the .22lr barrel, I wanted something more compact as well.


Left: .22lr barrel with compact over-barrel suppressor.


In this configuration, rifle is very short, very light and very quiet.


Right: I have always had an affinity with the 6 and 8 shot revolvers, and have used that look as the style for my ported muzzle.


Left: I wasn’t happy with the bead-blasted matte finish of the above suppressor, as it appeared to be hard to wipe marks off the body surface.

Note: It just started to rain while I was taking the photos.


Right: My solution was to polish the body to a mirror finish, and bead-blast my company logo into the surface.


Enjoy the video. The first half is displaying the rifle, and the second half is of the rifle being shot

There’s nothing quite as exhilarating as walking in the forest on a fine sunny day, pack on your back, birds singing, the sweet musty smell of nature and native fauna, and not another soul in sight – especially knowing you have a take-down rifle in your pack that can be assembled in seconds – allowing for that opportune shot or some target fun.

Normally the Papoose has been my choice of take-down rifle. The trouble is, that I buy one, modify and suppress it – and someone offers me a price I just can’t refuse! So, having sold my last Papoose to a very happy customer several months ago, I decided it’s time to replace it and begin a new project.

With no Papoose rifles available at a reasonable price, I decided to purchase a similar unit – a Rossi Survival Take-Down Rifle .22lr and .410 Combo. It is around 150mm shorter than the Papoose, meaning it is that much easier to carry in a back-pack.

With this Rossi, I will mount the scope on the removable barrel, meaning accuracy (with scope aligned to barrel) remains perfect every time it is assembled – unlike the Papoose which has the scope on the receiver, meaning alignment can be affected each time the barrel is connected. To be honest, this has never been that much of an issue, and possibly only results in a 50mm variation at 25meters or more – but it is always in the back of my mind – and causes a lack of confidence in a humane and instant kill.

The beauty of the set-up with the Rossi, is that I will be able to confidently hunt and shoot varmints with the .22lr barrel, and if a larger beast comes along, I can switch barrels in around 60 seconds, load a solid .410 slug or shot-gun cartridge into the chamber, and have a decent powered larger game rifle – that I can also hand-load for sub-sonic stealth.

Right: Photo – my Rossi as I purchased it.

This model is advertised as a Youth Combo, and is around 3/4 normal size. However, the stock and focus length is perfect for me.

Rifle is single-shot hammer action. This is something new for me, as all my other take-down rifles have been semi-autos. It’s actually a lot of fun, and gives a very different ‘feel’ and shooting experience and increases the skill required to ensure a well placed single shot.

Semis are always louder than bolt actions, even when suppressed – as a portion of noise escapes out of the chamber every time it cycles.

This hammer-action should prove to be as quiet as a bolt action.

Project List: Remove barrel sights. Thread .22lr barrel to 1/2″ unf x 20 tpi. Make over-barrel suppressor, drill and tap receiver in order to mount scope rail, attach butt cheek-pad raiser.

Left: The red unit is the end-cap with reverse flow venturi (cone shaped) extension. The silver item is the threaded mounting unit that screws onto the end of the barrel and allows the gasses and noise to port into the over-barrel portion of the suppressor.

Right: Beautiful anodized red finish on the end-cap unit.

Left: Ported muzzle. Very nice.

Right: Custom inbuilt muzzle-brake with skull and flames graphix permanently etched into the anodized finish.

Unfortunately I was holding the suppressor body in my lathe to align a unit inside it, and scratched it against a very sharp blade, meaning I have to strip the anodizing and start again.


The muzzle-brake/air-stripper is totally unique. As I began to make it, I had no idea how it would turn out, and just let my creative energies lead the way. I have never made one with a ‘slotted’ port, and are quite happy with the result.


Left: I decided to do a bit more with the re-anodizing, and went for a two tone, black to red muzzle.

.Click photos to enlarge.




I wanted the skull and flames to be a bit more of a ‘decayed’ look, as apposed to the clean lines of my first results.

Hopefully my ‘darker side’ isn’t coming out!


Left: Suppressor internals. I want this rifle to be as quiet as physically possible, for stealth hunting and shooting. With CB-Longs, this rifle will be absolutely silent, and with subs there should be a dull pop.


Notice too, the raised cheek pad on the stock, and the Weaver rail mounted on the .22lr barrel with fore-stock attached.



Right: Different view of suppressor internals.



Left: Photo showing multiple internal reverse-flow venturi units.

I will be able to fit in 25 suppression chambers – for optimal noise suppression.

You won’t get a quieter suppressor than this.


Right: I mounted this 2-6 x 32 zoom scope and low profile rings. The previous scope was too long and due to requiring high-rise mounts. The closer the scope to the barrel, the better.

However, the new lower scope presented a problem with the hammer. I just couldn’t fit my thumb between the hammer and the scope.

Left: I purchased a hammer-extension, and had to modify if to fit.


Right: From left of photo to right, .410 over-barrel suppressor with ported shroud, .410 barrel threaded to 9/16″ unf x 18 tpi, .22lr over-barrel suppressor, .22lr rifle barrel with 2-6×30 zoom scope, fore-stock with Bullter Creek pods, stock with cheek-raiser, combo safety lock.

Right: .22lr barrel threaded to 1/2″ unf x 20 tpi – with over-barrel suppressor mounted.



Left: .410 center-fire barrel fitted to rifle.

This barrel is threaded to 9/16″ unf x 18 tpi, as the rim-fire and center-fire suppressors can not be interchanged, being made from an entirely different construction technique.



Right: .410 over-barrel suppressor fitted. Suppressor has military hand-grip, ported muzzle, Matrix one piece suppression system and spiral pattern over-barrel ported shroud.

My next stage of the project will be to mount a Harris scope rail, and probably a red-dot scope targeting system.


BELOW: Update on this rifle project


Weaver Rail on Silencer Body - 13

NOTE: I can retro-fit a Weaver rail to any silencer that I have already made.

This is my own project for my Rossi Take-Down .22lr. I previously had a 20mm diameter carbon-fibre over-barrel silencer fitted, and while it worked excellently, due to the smaller diameter it had to be longer past the rifle barrel. I have decided to make a shorter custom over-barrel silencer out of ‘left over bits’ from other projects.


Specs: 34mm diameter, full body grip-strip, fully threaded and take-apart, custom suppression spacers individually hand-made from blaze polymer solid rod, custom splash anodizing. Very light, very quiet! Note: I have also retro-fitted a Weaver rail for accessories.
