Ruger’s all new short 10/22 with a built in suppressor (Video)

Ruger is back with another great option for their iconic 10/22 breakdown.

They’ve recently introduced the Silent-SR ISB, 10/22 with a built in suppressor.

Is this legal without a permit?

My thought exactly. Of course that is the List price.

BS!

You cannot silence a super-sonic projectile!

(More physics, less BS)

[robroys woman]

Sure you can. Acoustic feedback.

You can’t send acoustic feedback along the entire track of the projectile.

[robroys woman]

Not yet. ;-)

Wait...What!??

What You talking ‘Bout Willis?

[Big Red Badger]

Oh ..And you s..k...noob.

"BS!

Sure you can. Just slow it down. Which it's going to do of its own accord anyway ...eventually.

This rifle only has a 10" barrel with a 6" permanently-attached muzzle device (the suppressor). Any permanently-attached muzzle device is included in the BATF's accounting for total barrel length, which is how this weapon dodges the additional $200 tax for a short-barreled rifle.

Most "standard velocity" .22LR is subsonic when fired from a barrel as short as 16" (all .22 match ammo is), and I dare say even most "high velocity" ammunition will be subsonic from this 10" barrel. So I think you could shoot most any ammo you want from it and it still will be subsonic at the muzzle.

If it isn't SSS, it's easy to tell even without a chrono because the crack of the supersonic bullet makes a very discernible echo. It can be difficult to hear the difference with an unsuppressed rifle because the muzzle blast (which is only a couple of feet from the shooter) overpowers the echo (which is coming from some yards away) but with a suppressor, you can hear the echo of every shot that's supersonic (unless you're in the middle of the Bonneville Salt Flats and there's nothing within a mile for it to echo off of).

Offend..OFFEND!

The term "integral" when used in reference to a suppresor usually carries two connotations. The first is that it doesn't (substantially) lengthen the barrel. The second is that it somehow reduces muzzle velocity so that bespoke subsonic ammunition is not necessary.

It probably is more common to find integral suppressors made using a standard length barrel. Both the dual-objectives are served by "porting" the barrel, drilling a series of holes into the bore, then surrounding the barrel with a shroud containing the (sound and pressure-reducing) baffle stack. So propellant gasses are tapped off from the barrel and redirected into the shroud, leaving less pressure contained behind the bullet, reducing its velocity at the muzzle. The OSS's High Standard HDM of WWII was made this way:



And the ported-barrel integral suppressor is still common. That's what HK's MP5SD uses. And some of the aftermarket integrally-suppressed barrels for the Ruger MKIV and Browning Buckmark pistols.

But Ruger didn't want a barrel any shorter than 16" in this application because that would have made it necessary for the buyer to buy two $200 NFA tax stamps, one for the "silencer" (the term used on the BATFE Form 4) and the second for the short-barreled rifle (SBR). And starting with a a 16" barrel and porting it to achieve the desired effect only would have driven up manufacturing costs.

BATF accepts any muzzle device as part of the length of the entire barrel provided it is attached by a method they consider "permanent." Probably the most commonly used "approved" method is pinning (like bradding) used in conjunction with silver-soldering. For instance you could take the barrel off your AR15 to any NFA gunsmith and have him trim it down to 15", then add a muzzle brake or flash suppressor/hider or quick-disconnect for a suppressor, literally any muzzle device, so long as it extends >1" past the end of the barrel's muzzle, then have it pinned and silver-soldered. So long as it's at least 16" from the breechface to the end of the muzzle device, it dodges the additional SBR tax, even though the barrel itself is <16".

So Ruger skirted the whole SBR issue (reducing the buyer's tax liability by $200 in the doing) by permanently attaching a shroud which extends 16.12" from the breechface. From the perspective of the law, it's still a 16" bbl regardless of whether there's a baffle stack inside, otherwise the baffles couldn't (by the letter of the law) be removable. Which they need to be because rimfire powder is foul-burning stuff, and all rimfire cans need to be dis-assemble-able so they can be cleaned from time to time. But you'd be perfectly legal to shoot it with the baffle stack removed, because the shroud remains in place.

And I stand corrected. The barrel in this rifle is actually 10.62" in length, not ten even.

The 10/22 action cycles with subsonic rounds, no problem.
