just bought a 15-22 and it has a ser no starting with DEP, anyway to figure out when it was made?

Try this or contact them.

Serial Search

thanks, but tried it previously and came back as it did not fit the search

The link above is to look for guns under factory recall, so you don't want to find yours there!

Factory customer service will have the information, or the original box end label will also if you have it.
