No ........... the Pheonix (175 lb) has the standard stock. The Equinox (225 lb) and the Vortex (200 lb) have the thumb hole stock which is shorter by 1 inch in length. The thumb hole design is also about $60 (I think) more in price for it.
For taller or larger people I would recomend the standard stock. FOr shorter arms and smaller hands, the thumb hole would be better (more comfortable).
