ASI 4x10 Scope

[no good to me dead]

I've been looking around ebay...
and have found some scopes for $5.00 Buy it Now's.
Is this normal?
Yet they arn't ASI

also.... how long is the scope... so if I buy one for cheap that looks pretty much the same, I'll get the right length.

found this...

The "real" scope should be 11.5" long. The front and back lens pieces are slightly adjustable, so there's a bit of variance there... With eBay, a lot of people list compatible products in their description, so if ASI is referenced, it could mean the sight will work with Airsoft rifles.
