Reply To: Vortek PG2 kit question
The stock spring will not fit the Vortek guides. (Vortek spring is smaller in diameter). You can get the TBT guides from air rifle tuning.com that will fit your fac spring. I have the Vortek SHO and the 12fpe kit and found them to be good but I now am using the TBT guides with the fac spring and ARH piston and breech seals with very good results. Highly recommend the TBT guides with the fac spring.
