Method of Suppressing 15-22

Suppressed SBR in .300 ACC (Game Over)

No need to play around with a suppressed SBR in .22LR. Why give up accuracy and distance for something that looks cool.

Spend the money, have something that looks cool. And still have something that will out perform any other caliber suppressed in SBR.

While I agree on a 300 BLK SBR as being awesome, it has a few disadvantages. The 300 BO is a special purpose tool. It's well over a dollar a round now. That right there can take the fun out of plinking. It's not close to being as quiet as a .22LR, even with the best suppressed integral, the Liberty Suppressors Leonidas.

Here's mine. I much prefer to shoot my suppressed SBR 15-22 on a daily basis over my suppressed 300 BO SBR.

crofoot629: I just spoke to the company and they are using a 10" barrel, ports, and their can. Interesting setup that appears well thought out , to maintain accuracy, sound suppression, cleaning ability. It will be quiet with bulk ammo and still be user friendly. I watched their videos- impressive- and will let you know how mine sounds, works when I get it. Be Safe,

Thanks for the I formation.
It still seems to me that a 10" barrel would shoot high velocity ammo at super sonic speeds?

A 10" AR that was suppressed and stayed sub sonic would be a hoot!

OP ( or others) how does the intregally suppressed keep the bullet from being super sonic out of a 16" barrel? Does this method slow the bullet down?

How's the intregally surpressed rifle work if it has a 16" barrel to keep rounds subsonic? I'm clearly missing something here.

Emory

All these methods don't slow bullets down. They keep bullets from reaching enough velocity to break the sound barrier.

Standard velocity or subsonic ammo keep their ammo from reaching the sound barrier on long barrels. Short barrels or ported barrels keep the high velocity bullets from reaching the sound barrier. Here is a guide. BBTI - Ballistics by the Inch :: .22 Results

You would need to use subsonic or standard velocity ammo for that. Most people pick which ever velocity ammo stays subsonic and maintains reliable function of the host.

Yep, hence the 3.5" barrel on my MKIII.
So the 10" intregally suppressed barrel has "ports" that bleed of gas never allowing the bullet to go super sonic. Because a 10" barrel would be super sonic with most 36 grn HV ammo with a Can on the end of the barrel.

I am actually waiting on stamps for a 7.62 suppressor and SBR for exactly that caliber.

It has a totally different purpose than a .22 though.

vipermd · Jul 30, 2013

crofoot629: I wish a 10" 223 were "super quiet" but you are dealing with a velocity of 2700+/- compared to a 22 lr that is in the 1100 +/- range, so it is just easier to get there from here! Physics still rules. Be Safe,

Partially because I don't want to have to rely on buying a specific kind of ammo. Also, I was shooting some "subsonic" ammo that still went supersonic out of the 16" barrel. I have a bunch of CCI standard velocity that stays subsonic, but I have thousands of more rounds of other ammo that is supersonic. And this type of bulk pack ammo is readily available, under typical conditions (ignoring current ammo shortages). Much nicer for me to walk into Wal-Mart and pick up a couple of bricks of ammo and be able to shoot it suppressed, or use whatever ammo my friends have brought with them.

I have other suppressors in different calibers, and realize when using them that ammunition selection is key to effective silencing. However, I do not want to have to be picky about ammo with a 22. I know I mentioned price as a factor, but freedom to use cheap readily available ammo and get the same results is worth it to me. My question was regarding weapons, not ammo.

The problem with that is that even with 40g Minimags rated at 1235 FPS to get the velocity consisently below 1126 FPS (sea level) the barrel has to be somewhere in the 6" range. If you live higher than sea level the SB is even lower and it decreases even more as the temp goes down. For Fed 550 bulk it would have to be even shorter. Are you prepared to have a 15-22 with a barrel as short as a Ruger or Browning pistol? Might as well find a 15-22 pistol instead.

Like others have said most who want to suppress a .22 and use HV ammo either get a short barreled pistol made (or a Tac Sol 4" threaded barrel added to a Ruger or Browning)or buy a Browning Buckmark Micro (4").

fire any suppressed weapon into a good backstop 10 feet away and you will not hear it since it can't get up to speed.
You need to learn something about firearm ballistics friend. As soon as the bullet leaves the barrel it starts slowing down because there is no longer any gas pushing it. Anyone who has ever used a chronograph knows this. There is only one firearm in the history of personal weapons that this does not apply to, the Gyrojet Rocket Pistol. Look it up if you don't know why.

In my original post I mentioned a 4.5" barrel, so I am well aware it would be under 6". And I also mentioned already having and using my Sparrow on pistols. I don't want another pistol. I want a gun with a shoulder stock, proper 2 hand grip, and a cheek weld. That length barrel with a shoulder stock and a handguard covering most of the suppressor would be about the same length as a 7-10" barreled ar15. Shot some of those and that is a quite handy length.

After getting some info via pm and phone calls though, it is looking like I may give the integral 15-22 from Innovative Arms a try. Still mulling things over for now

Trying to understand your logic... not put you down. This interests me as I'm awaiting my stamp on my 22Sparrow.

Since you already have a 15-22 and a 22Sparrow, what does the Innovative Arms gun give you that you don't already have? Would that suppressor not be much more difficult to clean than a Sparrow?

What it would give me is a firearm that shoots bulk ammo that stays subsonic out of a shoulder fired weapon. Quiet like my pistol with the sparrow and no sonic crack.

As far as cleaning goes, the integral gun has a shortened and ported barrel. The baffles on the end of that are a monocore baffle stack exactly like what all the easy to clean silencers from Silencerco, AAC, or etc use. Take endcap off and remove baffle stack, then clean and reassemble. Only difficult part seems that it would be swabbing out the sleeve over the barrel where the ports might let some crud out. I think a cleaning rod would get that done just fine.

Besides, part of my shooting ritual is to come home afterwards and clean my guns while sitting in front of the tv. A couple of tv episodes or a movie later and I am done. I don't see frustration in that, more like meditation

jonniemactyler · Aug 1, 2013

Also Redneck, you won't be disappointed by the Sparrow. It is a great can that I would recommend to anybody. 1 of the best options out there for a 22 silencer.

Good luck on getting consistent quiet reports with HV ammo, no matter what you do to your firearm. Suppressed operation IS very ammo-dependent. There a reason subsonic ammo is below 1,000 fps.

You can't change the laws of physics.

The Major is correct in all respects on this, but for one small exception: the speed of sound is 1,126fps.

Almost all match grade 22LR is below 1,060. Most is around 1,040fps.

If you want to assure the bullet does not go supersonic out of the barrel, use ammunition designed for the purpose.

I shoot CCI SS and SS Segmented out of my 15-22 with an AAC Element and it is very quiet, both at the muzzle and down range. Any match ammo that I have used is equally as quiet. If that is what you desire, use the right ammo.

As for the comments about shooting dirty; that's any can, on any gun, with any ammo.

Is the baffle stack Stainless?

Do you have to purchase two stamps... one for being SBR and one for the suppressor?

Seems like a cool gun but doesn't make sense to me. But that is not important because a lot of what I have doesn't make sense to others, and in the US of A you don't have to justify play things... well maybe to the wife. Just seems like this gun looks, feels and acts just like your 15-22 with the Sparrow. Looks like you are spending $1500+ just to shoot bulk ammo. Even during these trying times, I have still been able to purchase thousands of rounds of subsonic ammo. That is pretty much all I purchase nowadays.

So if I do some simple math and assume my subsonic ammo costs .03 more than bulk (just throwing numbers out), that means for that $1500 I could purchase 50,000 rounds of the more expensive ammo. That is a lot of shooting. Even now on Gunbroker, with those high costs, I can purchase 5000 rounds of CCI Standard Velocity for $ 575, so there is plenty of ammo out there.

Once again, you don't have to justify anything to me. I just don't see the importance of shooting bulk ammo in the purchase equation.

jonniemactyler · Aug 1, 2013

Redneck, the baffles are stainless.

It is only 1 stamp for the suppressor, which is an integral part of the barrel. The length of that unit is over 16", so it isn't an SBR. Same way an AMD-65 is not an SBR even though the barrel is 12", it has a permanently attached muzzle brake that makes it over 16".

The msrp for that Innovative Arms gun is $1150, but it is much cheaper than that if I just send him my upper and let him build it off that.

Maybe I am crazy regarding the ammo, but another way to look at it is this...In every type of shooting except suppressed shooting I prefer my rounds to have as high a velocity as possible. That said, if I am going to buy up ammo then I would prefer the high velocity type. As I said, maybe crazy to you but it makes sense in my twisted little mind because I don't believe in having a stock of ammo that I am only going to use in 1 gun, and only when that gun has a can on it.

Just to be clear, I did not say, or even intimate, that the speed of sound was 1,000 fps. I simply stated that subsonic ammo was generally below that figure.

ken158 · Aug 1, 2013

If you want to suppress a .22 in an AR platform - SBR a regular AR lower and then you can get a dedicated upper in any caliber ie: 22 LR, 300 BO or whatever. Use a dedicated integral or screw on suppressor. (I have both and works well) I have not found that sub sonic ammo works very well in a .22 auto but standard velocity and even high velocity does and suppresses well. As far as the 300 BO comment about $1 a round, anyone that shoots one of these should really reload... I sure enjoy mine in a bolt gun and semi auto. Considering the 55K backlog of ATF form 4's, I would say that 99% not having funds for toys is quite a bit off. Most of the guys here have plenty of "toys" as well as safe queens (which are a real waste of $$$) And - as long as the bills are paid, I will buy anything I want.

Understood and I stand corrected. Most of the sub-sonic stuff is around 1,040fps.
