anyone else seen these?

Very popular for urban deer work. The USDA-APHIS-WDC folks here have used one ffor several years for urban work with good results.

i could see a thin arrow hauling some serious ??? out of a .22 if using a really hot blank. sounds like a neat idea

I believe these conversions use "powerloads" Which are NOT standard 22 rimfire blanks. They"re used to drive specialty nails & fasteners into concrete slabs. They come color coded indicating the power level. Believe Remington is the major manufacturer. Although they're not as loud as a centerfire, they aren't "quiet" by a long shot. That said looks like a neat concept.

Sounds like a hi-tech poachers weapon. Neat, but not very useful except in special circumstances.

Good Shooting

Drew one up in A'Cad/reverse eng'd & just waiting for The Bud to whip one out. Prolly require some tweaking. Curious about that outer shroud - maybe for gas blow-back ...?

The 10/22 is a very apt platform due to the barrel mounting. Depending on stock config, one could enlarge the receiver to hold just about any size cartidge (read that as a blank) as one would wish ....

Still , a pretty impressive idea all told.

If one is inclined to build something along these lines....
Researchin the Smith Model 17-2 could give some ideas on how they work.
The smith used .22 RamSet type blanks to propell an assortment of .53 caliber projectiles. from darts to paint to shaped charges.

do you suppose it takes that same blanks used in a hilti gun? (nailgun run on .22 power blanks?)

Years ago, my grandfather and his bother took the feathers off an arrow.
Then they remove the pellets from a .410 shell. The loaded up the 410 but
the arrow down the barrel and pulled the trigger.

Well, the gun held up to this little "experiment" and the arrow hit a tree
some 40 yards away and just wiped itself out to the point of not being sure
it was and arrow

The next problem is that, ya the arrow went 40 yards. The target they were
aiming at was only 15 yards away and about 8 feet to the right of the
tree.

Needless to say, I readed them the riot act on doing something so stupid.
My mom and grandma said it was the most amazing thing to see this 22 year
old Kid (at the time) yelling at his grandfather and great uncle and them
stand there taking it.

Best thing...... they never tried that again.

I've seen the same thing as Black Dragon. One of my friends cut the pellets out of a low brass 4-10 shell and loaded an aluminum crossbow arrow with the expandable braodhead (so it would fit down the bbl. of the gun). It was impressive to say the least. The only difference is that his was accurate (for the most part). You don't want to try to use a high brass or 3" shell for it though.

"did you build yours with a 22 cal inner barrel? or smaller for higher pressures?"

Not built yet. Just drew up the receiver & fed the file to the bud w/the shop ... waiting.

I dunno if the inner diameter of the tube matters all that much. The arrow's nock is cut off & slides over the tube. Seems the clearance between the arrow/tube would be the deciding factor all things equal.

Far as the shroud-thing, may get some gas blow-back when the arrow clears the tube end. Dunno.

The arrows used in these products are #2512 and 16†in length. Using 75 grain target points the total arrow weight is 305 grains. They feature a hollow aluminum shaft, with the back of each shaft left open, immediately behind the fletching for installation to the barrel.


The barrel used in these AIRROW rifles consists of two barrels: an outer barrel (shroud) with an outside diameter of .920†and a second floating inner barrel. The inner barrel fits inside the hollow shaft of the 2512 arrow. The fletching must roll over to fit inside the outer barrel (shroud) and the shooter is advised to use a rotating clock-wise motion as he first fits the arrow to the inner barrel and then pushes it down inside the outer barrel (shroud).

The Airrow blanks used in these rifles are available in two different power levels and each power level has its own color code for easy identification. Power Level 5 is colored Red and demonstrates a nominal muzzle velocity of 335 fps with the 2512 arrow, while Power Level 6 is color coded Purple and has an approximate muzzle velocity of 435 fps with the same arrow. The resulting muzzle energies are 76 and 128 foot pounds respectively.

i gather arrow firing rifles are not SAWs

"it seems to turn bambi into venison:"

I bet.

Talking about 1" groups at 50 yards & close to 500 fps ...

Still a "firearm" by all CO state laws, but there's a certain nicher here - for something or 'nuther ....

I mind you, we haven't a working model yet, but ...

"it uses the fletching of the arrow to center the inner barrel, "

Sounds like BS. As you pointed out, fletching varies.

Still waiting for the first model. I spec'd the arrows out for 2117 standard lengths (what I have on hand) & a .005" IO/OD clearance - arrow-to-tube. Rigid tube to rceiver fit- eiether thermal or epoxy .... whatever seems to play out best.

We'll see.

<sigh> So many toys, so little time. And money.
