Which bullpup AK?
Valmet? Norinco? Century International Arms?
If it's a Valmet, then congrats! You just scored on a excellent piece of Finnish engineering and you are in a select ownership club (less than 1000 were imported into the USA).
If it's a Norinco, then congrats! You just scored on a good piece of Chinese engineering and you are in a select ownership club (less than 2000 were imported into the USA). Watch out for the charging handle, it likes to bite when you operate it.
If it's K-Var/Century International Arms bullpup kit gun, then I hope you can find enjoyment in the crappy/mushy trigger and overheating issues.
