Is a Stevens model 200 in 223 offered in a youth model?

No. Stevens 200 is not offered in a youth model.

Stevens is a value line of firearms made by Savage and is essentially a Savage 110 without the Accutrigger. It only comes in one size of gray polymer stock.

However, since it is the same action as a Savage 110, all 110 accessories will fit, and the stock can be replaced with a shorter one.
