Some air rifles have a ‘silencer’ attached.

Possibly the person claiming that rifle had a silencer attached is not gun-savvy enough to be qualified in making that claim.

More info required before commenting to be fair.

I wouldn't say there's many air guns that would outstrip a .22LR in terms of performance figures.

None that can be bought without a firearms licence anyway

Any .22 Air rifles, that could would have enough power would be getting into pre charged pneumatic specially dangerous category.

I was just doing some looking into the air rifle performance figures at the weekend.
My .22 gamo Maxim air gun shoots a 1.05gram pellet about 710fps.
Quick calculation rates it at just over 24 joules of kenetic energy
Which is what most air guns in gamos catalog are rated at.

The most powerful .22 break barreled air rifle I've see for sale locally the Gamo Swarm Magnum, at 36 joules its no joke...

But let's do the math, and calculate the impact kenetic energy of a .22LR bullet in Joules = 1/2 Mass(kg) × Velocity² (M/S) is your formula.
So a 40 grain standard Velocity .22lr bullet at 1070FPS
Converted and calculated is a 2.592 gram bullet at 326 metres per second = 137.73 joules

To match that a 1.05gram .22cal air gun pellet would need to travel at 512m/s or 1679 fps.
If you can show me a break barreled air gun that can do those figures I'll be shocked, impressed and may need to go shopping..
