Looking for a suppressor for the Springfield Armory Saint pistol 223 with the 7.5" barrel. Springfield Armory will not tell me anything. I have been looking at the full auto cans but can"t find one for that short off a barrel. Can you put a Suppressor on that short of a barrel? Any help would be great.
 
Since springfield doesnt make suppressors they would be of no help. You need to look at the suppressor specs.
I run a Crux on my 8" SBR. Let me tell you what, it gets hot and hot FAST. If you shoot high volume it could damage the can. 40rounds in under 60 seconds will put the can near the 800 degree limit for Titanium.
 
I have one of these also. It has NO barrel retrictions. Read the discription.

Full Auto rated down to 10.5, but full auto rating doesn't mean much to you. Full auto can do a 30rd mag dump in under 10 sec. You have to not over heat the suppressor is all. That is why I have multiple supressors and multiple firearms. I let mine cool down after a quick mag.
22lr is one you can shoot hundreds through. My 22lr can rarely gets warm to the touch.

Thunderbeast are nice, and the take-down looks to be an excellent price. The take down and the other rated for 7" SBR are made of stainless and inconel. they can handle more heat than TI but are a lot heavier. Everything is a trade off.
 
New here ... sorry if I sound a little dim. Just getting into these forums although I've been distance shooting for years. Preferences are my LWRC .308 and 6.5 REPR's with my SilencerCo Chimera. I also have several AR's and a safe full of SIG pistols.

Here's my issue ...

I've had a Saint Pistol for about a year and generally like it, but it's very loud and I'd love to suppress it. The problem is that the hand guard is tight (1.25" diameter) and it covers the threads, making the ASR mount for the Chimera generally useless. I've looked at shorter hand guards from MI and SLR, but I'd dearly love to solve this problem without ripping the barrel apart and replacing gas blocks or barrel nuts.

I was reading this thread (and others), but none of the suggestions would actually work for suppressing a Saint Pistol without extensive (and expensive) modifications. I'm interested to know if anybody has actually figured this out, and is using a suppressed Saint Pistol, and can share their actual working solution? Thanks!
 
Thanks Smokin' ... but I need a little more guidance. I went to the Aero Precision site and searched every "thing" and every "product" there, including a search specifically on "forend". Nothing that works .... no grips that don't require a new barrel nut. Am I missing your intent? Can you share a specific link of "the thing" that gives me that simple fix? Getting ready to buy the Midwest Industries MI-SP7M ... looks like it will work, but I'll have to change out the barrel nut. So be it ... the video makes it look OK, and I have all the right tools.

I was hoping to find a slightly shorter hand-guard built for the same Saint barrel nut, but I've decided that's going to be an unanswered prayer.
 
Have you tried contacting s&w to see if it's a standard nut?
 
It's a very odd nut design with the barrel screws set much further apart than anything I've ever seen ... also I contacted Springfield for help, and this is what came back when I asked for advice:

Good Morning,

Thank you for contacting Springfield Armory. Unfortunately, we do not customize or offer any upgrading services with the Saint line of rifles.

If you change hand guards, you will have to change your barrel nut as well, most likely. I wouldn't plan on finding a hand guard that uses the same barrel nut as the Saint. You may be able to. But just plan on changing the nut as well. It's not difficult, with all the correct tools it shouldn't take longer then 20 min or so. If you don't feel comfortable doing it, you can always try and find a smith or something close to you that will do it.

Cheaper option, you could take the existing hand guard off. And take a saw to it to take off an inch or however much is needed. I wouldn't recommend this, I say just get a new handguard, but it will work.

Yikes ... taking a saw to a barrel for me would fall into the category of "Cruel and unusual punishment" (for the barrel). Besides, I have the opposite problem where the barrel is too short (or the hand guard is too long). I bought the shorter hand guard from Midwest Industries and I'm going to give it a go. I've replaced muzzle brakes, triggers, stocks, and stuff like that ... I even installed a Law Tactical Folding Stock Adapter ... so I think of myself as a "Unsupervised Situational Novice Junior Amateur Apprentice Gunsmith". But never a barrel nut or gas block. I'll report back with photos of my glorious victory (or descriptions of my dismal failure).

I said take off the end of the handguard, not the barrel.

Oh ... sorry ... in that case it would be "Cruel and unusual punishment" for the hand-guard. Also, the pic-rail is smooth until it gets to three slots at the end, so if I saw off the hand guard, I get no chance for backup sights (ever). I've got a new hand-guard on the way, and I'm going to try that.
 
New handguard is definitely the way to go. You just seemed a little apprehensive about trying it in your earlier posts, So I was just giving you an alternative.
 
If "apprehensive" translates to "friggin' terrified" ... then you assessed me correctly.

I'm going to give it a try anyway. Hey ... I've got tools, YouTube, and spare guns.

What could go wrong? :oops:

It's not too bad. Only thing that may cause issues, is how much loctite was used when it was assembled at the factory. A torch or heat gun will come in handy.
 
Got it ... good advice. Normal threads ... right? Lefty-Loosey / Righty-Tighty? Not that weird left-threaded stuff that SIG does on their barrels.
 
Worked out GREAT ... got the one below, and it came with a barrel nut (extra $4.99) that worked perfectly. Now my Saint Pistol has plenty of room for my suppressor, and it shoots quietly and accurately. One of my favorites. Also had to buy a special barrel nut wrench to remove the stock nut. I'll put that link below too.

Which suppressor did you go with to actually quiet it down a good bit. With a 7.5” barrel on a 5.56 I figured it’d still be a cannon even with the suppressor

The SilencerCo Chimera-300 ... it's terrific. I have ASR brakes on all my rifles (5.56, 300-BLK, 6.5-CM, 300-WM, 308-Win) and it just pops on and off all of them. I bring welding gloves to the range to take it on and off (and back on) even when it's hot. I have 7 suppressors, and two of them are Chimera-300's ... definitely my favorite multi-caliber can. (Photo of my "Can Briefcase" is below.)

Fantastic, that’s the one I’m looking at as well.
You'll find that even on a short barrel, it's got great sound suppression and recoil mitigation. Even on my 300-WinMag ... it's damn near hearing safe. That said, anybody that shoots anything without hearing protection, is asking for hearing loss eventually ... except 22's, and subsonics like 300-BLK. I have an Adams Arms 300-BLK pistol that I shoot subsonic, and it's super quiet. The only things that hear it on my ranch ... are the Rock-Chucks ... just before they die.

One you might want to look at is the SC Omega 36M ... modular, multi-caliber, works on pistols too. I just got mine and I'm liking it a lot so far. If you want to suppress literally "everything", it's a great option. Rifles only ... then the Chimera-300.

Agreed, I always wear hearing except when hunting usually. Lol I’m gonna have to do a 300 BlK out one of these days

What all did you have to do to get that ION handguard on your Saint? I got the same one and it came with a threaded nut inside it and it won't fit on my Saint 7.5"
 
For anyone curious, I have one of these 7.5" pistols with the 8.5" handguard, and I'm working with a company that makes custom muzzle brakes and suppressor mounts, and they said they could and would be willing to make one for me, that is slightly extended in length to be able to clear the factory handguard to allow me to run my Dead Air cans with KeyMo mounts, without any modifications, but installing the new extended length KeyMount brake.

Once I get mine made, and get permission to announce who it is that is making it (VERY renowned company), if it is a popularly requested item, it might become one of their stocking items, and they might make more of them. So, just posting this up for any SAINT VICTOR 7.5" pistol owners in the future, who are wanting to suppress their gun without having to replace the handguard, and modify anything, other than swapping out the muzzle device. 👍🏼

Also, incase anyone is curious, the Dead Air Sandman series and the Nomad-30 and Nomad-L do not have barrel length ratings for 5.56. The Sandman would be the heavier duty option with the solid stellite baffle stack that can handle full-auto SBR's in 5.56. The Nomad cans can also handle it, it's just recommended that you time your shots about a 1-2 seconds apart, and don't do any full-auto, binary, echo, or mag-dumps.

I removed the Saint barrel nut and used the barrel nut that came with the SLR hand-guard. You need that special barrel nut tool from BCM to get the Saint barrel nut off. It's really hard to remove, but I was able to get it off using that tool and a long breaker bar.

I bought that tool after I saw your post. Just didn't know how to use it. Thanks for the info!

I bought the SiCo Saker ASR556K can with the Dead air key mo charlie mount. I'd like to use my factory handguard, so your option would be better for me. Please keep me posted.

They said they are VERY busy right now with the current run on things, but once they slow down some, they'll make me one. So, I'll keep this thread posted.

Ok, thanks. I spoke to Capitol Armory this morning and Jorge stated that this wasn't a good option because it's a Dead air product and likely won't be from hardened steel. Said there'd be license infringement on behalf of any other company if they make one that fits the Dead air mount, so they can't market them. Makes sense, but I'm still interested if it works for you.

Jorge WOULD normally be correct.... BUT... It's a company that already makes tons of custom DA mounts... They are already licensed and approved BY Dead Air to produce them. It will be legit. And YES, they can market them. I don't know for certain, but they might actually be the company that makes ALL the mounts FOR Dead Air in the first place? 🤷🏼 I wouldn't be surprised. So, you have nothing to worry about, with the product being legit and correct. They're a very well-known and legit company that's been around forever, I just can't announce who it is right now, because I don't want them to get bombarded with phone calls and emails about it. 👍🏼

I understand. Did they give you any kind of time frame? I may just use the SLR handguard until the other option comes available and I can switch it out. I appreciate all the info you guys have put on this thread!

No, they didn't. I did tell him that my stamps should be back by May, so hopefully before then.

When you swapped out that barrel nut, did it affect the gun in any way or did it shoot or sound differently?
I didn't remove mine, but I've built lots of AR's... Are you talking about the barrel nut that holds the barrel in the upper receiver? If so, then it shouldn't affect how it sounds at all... Any time you remove and reinstall the barrel, I'd re-check your zero to make sure your optic is still on.

You're not talking about the big round compensator that is screwed onto the end of the barrel with the holes in it, are you? If so, then yes, it can affect how it shoots, and will affect how it sounds.

I’m waiting on a Nomad-30 for my SAINT. What parts or accessories would I need for the can to the barrel such as adapters or disconnects?

You don't need any adapters, you just need the extended mount. It will be 1 solid CNC machined piece for consistence and concentricity, just like a regular KeyMount Brake, just a longer distance from the thread to the locking lugs. If you try to use an adapter, you're likely to have issues. That's why this mount is being made by a professional company that builds and designs such things.

My question now is, what to do about the gas tube that's in the way?
How is the gas tube in the way? We're talking about swapping out the big round compensator on the OTHER end of the barrel...The muzzle end, where the bullets come out...

Are you trying to remove the barrel/nut? Drift-out the gas tube pin with with a gas tube pin punch and small brass hammer. There's a tiny little pin holding it into the gas block. Just be VERY careful with it.

If you are trying to do this, and have no prior AR or gunsmithing experience, I'd consult a professional before attempting to remove the barrel/nut to swap on a new handguard.

I have some experience and I've changed alot of parts out, but nothing like this. Just been trying to research and do as much as possible by myself. But I don't want to mess anything up. I believe I'll take it to the gunsmith when my flash hider arrives and just let him do it all.

Hello All,
MudRunner2005, I'd be interested in the same muzzle device you've commissioned to be built. I also have a SAINT 7.5" and have a Dead Air Sandman-S working its way through the ATF process, about 7 months to go I think.
Question for others who are still on this thread, any reason why you chose the route of changing the handguard -vs- changing the barrel? Bear Creek arsenal has an 8.5" 5.56 barrel I've also seen 9" 5.56 barrels as well. I was thinking/hoping that 8.5" would be enough to clear the handguard for the Keymo muzzle brake. I really like the handguard on the SAINT and don't want to swap that out or modify it.
 
I like the handguard, as well. That's why I don't want to swap mine out either. I looked into barrels. Rainier Arms also makes a 8.5" 5.56 barrel with pistol-length gas system (out of stock, of course from all the panic-buying 🙄). And I've been running Rainier Arms barrels for years. Amazing quality. I've heard a lot of bad about BCA, so I'd personally steer-clear of them. Then again, how accurate can a 7.5" 5.56 actually be, and how far are you realistically going to shoot with one... 🤷🏼

I need to contact them back to see if they ever got around to making one of those muzzle brakes. I'll let them know more people are asking/interested in one. Thanks for the input! That might help spur them along. If you know any other Saint 7.5" owners that would want one, tell them to join and post up in here. The more interest we get, the more we have a chance of making this more than just a 1-off custom.
