So the firearm used is a Phoenix arms HP22A. The exposed barrel is not enough to thread with out machining down the barrel slide.

To make a long story short how well do you guys think JB welding a bolt that is larger diameter than the barrel to the end of the barrel. Then using a MtM threaded adapter attaching the suppressor.

Would the muzzle blast or recoil of the slide knock the bolt off? Firing the HP22 into a bucket filled with memory foam I found that quite a bit of sound is escaping from the ejection port. probably because the break on the slide is the whole top of the handgun. Unlike say a MKII or a 1911. its more like how the Ruger 98 is. Wrapping a rag around the handgun fixed this but it can interfere with firing multiple shots. Is this because the brass is not expanding enough and the gas is being blown back? Or is this just the case with this gun? I'm using Federal Classic
 
What do I think about it? I think you've created or will create an illegal device. But then I'm no lawyer and I didn't sleep at Holiday Inn Express last night.
 
Guys, he didn't say he has an unregistered, illegal suppressor. He said he's trying to make an adapter for a Phoenix pistol so he can use his suppressor (assumed to be lawfully owned) to that gun.

Even though it's a Phoenix, that's not illegal. :D

Now, I don't think JB weld is going to be the right choice. Threads for suppressors have to be machined very precisely and square to the bore so you don't get baffle strikes and destroy your expensive, lawfully owned, suppressor! JB welding a drilled-out bolt won't be nearly precise enough for this critical task.
 
Look to how its done on guns like the Walter P22 and S&W M&P Compact.

The barrels are basically flush with the slide but they have been turned down and threaded so an adaptor that fits inside the slide opening can be installed that extends the barrel outside the slide for the suppressor. I doubt anyone markets one for the Phoenix pistol, but if the barrel has enough "meat" I suspect you could have it turned down, threaded, and a custom adaptor made -- although it might be cheaper to just buy a .22lr pistol with a threaded barrel.
 
One of the big selling points for the Phoenix is its ability to take an accessory long barrel to make it more suitable for target shooting/plinking.......

why not start with the longer barrel unit?

DO be aware that suppressors are highly regulated and taxed and some states frown on having barrels threaded for them.

Are the barrels solid steel or a lined zinc based material?

He isn't talking about fabricating anything that even closely resembles a silencer as far as the ATF is concerned. He is simply asking about a homemade adapter to attach the suppressor to the host firearm.
 
Most of you got the point here. none of you could possibly know if I have my ffl and class 3. Anyway he legality is not of discussion I simply want some incite on suppressing a Phoenix Arms hp22

As for misalignment is concerned. The attachment would be fabricated after the adapter is fixed to the barrel ensure its alignment... Basically it will be a suppressor unique to that build...

I did a laser alignment of my barrel and found that my rear sights can not go far enough right to line up dead nuts with the front sight and the line of fire from the barrel.:scrutiny: I thought she was shooting a little to the left but damn for a fixed barrel its not very accurate. I mean at 10 feet it is noticeably firing left and the sight adjustment screw will fall out if i turn it anymore. Thats a story for another day.:uhoh:

Something to consider would be to convert the extended barrel into a suppressor of its own. The issue of the escaping gases from the breach is still going to be an issue though maybe just an ammo issue as I am stockpiled on Federal classics. I have yer to try other ammo. So far wrapping a towel around it kills the noise, but can interfere with ejecting shells/ hammer hitting/slide closing back .ect :banghead:

I think the project is doomed to failure since JB Weld will not hold up supporting much in the way of lateral forces that would undoubtedly impact the suppressor at various times.
 
Given all the safeties on a Phoenix is there one that holds the slide shut that might be modified to not be a safety but only a slide lock?

JB weld won't work. Not enough "meat" there for it to grab onto.

You have a couple options. You could weld the bolt (or other threaded adapter) to the barrel. I would use my TIG, and be VERY careful how I set it up to ensure concentricity.

Option two is to put the barrel in a lathe, spin the front sight/shroud thing off and thread it for a custom adapter. The lathe will get you concentric.

Option 3 (Ghetto) would be to use a bigger bolt/adaptor, notch it to go around the barrel and have enough meat to Epoxy it. (I still wouldn't use JB weld, but rather a more industrial metal epoxy.) This would be a much more "Garage" style and I would recommend using a large bore on the silencer to avoid baffle strikes.

Realistically, if you don't already have the tools, you'd spend more to do it correctly then a threaded .22 host would cost. The ghetto way is not good for long term use.

As far as sound escaping the breech, it's a blowback weapon, so by design the breech opens with some pressure there. Adding spring pressure or weight to the slide will delay opening and decrease the pressure release, but could impact cycling. You'd have to experiment a bit. The suppressor will increase pressure and make that worse, so experiment after you have it mounted.
 
If you really want to reduce the noise of action and any blast escaping from it you'll have to lock the slide closed in some fashion. This will convert the weapon to a single shot pistol, but it will be dang quiet if you have a good can on it.

Check with EWK Arms. Eric can back bore the muzzle, and install his custom adapter. That way you retain the front sight, and have a solid, concentric attachment. He has quoted me around $90 for other barrels, so I would think the job would be in that price range.

Very little sound comes from the ejection port on a properly suppressed 22 pistol.
 
Ditto... no go on the JB Weld. Every shot fired will create micro fractures in this brittle compound. I would be surprised if it survived one mag full. Beyond that, your barrel would be ruined forever.

My thoughts: anything worth doing is worth doing right. Have the barrel threaded by a gunsmith and buy an adapter.
 
just ordered the longer barrel. I have a MIG welder so I'm gonna chop the barrel and weld the threaded adapter.... Or possibly.....weld the suppressor to the barrel and make it more like a MKII hush puppy. The removal of the barrel would be faster than screwing anything on and off anyway. hp22sup.png Ill post pictures when i finish it. Ill have to make one of those maglight suppressors because no way am I welding my gemtech or any quality suppressor to anything. lol.
 
Attaching a $200 tax to a $98 dollar pistol?

Seems questionable as do some of the proposed notions for implementing it.

It's walking like a duck...

Phoenix, JB Weld, Maglite suppressor...got all the bases covered, I see :rolleyes:

"...oh btw, I'm an SOT"

Sounds like troll-bait. But for fun's sake; turn down the zinc shroud enough to get some threads in the barrel (or an adapter) and that's the only solution.

"back bore the muzzle, and install his custom adapter"
And single cut the threads blindly to an inside shoulder using a very small tool. Guaranteed scrapped barrel or hundreds in labor (assuming you aren't laughed out the door). Or maybe a press-fit mount wouldn't blow off during the first magazine?

"weld the suppressor to the barrel"
Try not to get any melted zinc on you, or breath any of the fumes, bud :cool:

Yeah - they kinda are when it comes to supporting the impression of buying in to the point to be doing this legally.

Or - is the guy asking how to tape a turbo to his Yugo likely to be serious enough to upgrade the brakes, clutch... etc. Turns out the car isn't even registered or insured - who'd be surprised?

EWK Arms has been doing S&W Model 41 barrels in this manner for years. If you dont think its possible, maybe you should call them on the phone, have them explain the process, and you might learn something. The barrel has to be thick enough for the threads, so they only do bull barrels

Zinc poisoning sucks!

If you could make an alignment tool, a rod that would fit through the suppressor and into the barrel.

If you can make a bushing that has the proper thread pitch that would protrude from the suppressor.

If you can align all this with your alignment rod while silver soldering the bushing to the barrel.

Its easy!
