Yes and no. The #1 is attached like the 452 Varmint 1 action screw and a barrel screw, other 452 models have 2 action screws and no barrel screw. The #1 i have will fit my 452 v stock altho the barrel channel is not the same, and the trigger guard is different. So it will not be a easy dropin with a little bit of wood work and some glass bedding it will work. The 452 line has several differnt models and different stocks so their may be one closer. I don`t know off the top of my head which 452 may be a closer fit, but i wouldn`t be overly concerned about the mods to the stock myself. Depends on how much stock works you do and what it`s worth to you.
