Quiet time, at under $1K
So ARMTAC is marketing the coolest little (and I do mean little by design when compared to a 10/22 with a screw-on can) rimfire rifles.

They have taken Ruger 10/22 rifles, added a Hogue Overmold stock, and equipped the whole thing with a ARMTAC Monotube integral suppressor. Brand new assemblies run $975 plus stamp (which hopefully the HPA passes next year so…)
Of course you could buy your own 10/22 ($309 MSRP for base 1103 model), forgo the overmold stock above (-$90), get a replacement threaded barrel (starting at $100) and get a low-end screw on can for $99 (Rebel markets a decent one for that price plus stamp) but it’s not integral and certainly won’t be as smooth as the above. Mileage varies.
