The earlier FN's did come with a HS Precision stock.... but the SPR's now come with a McMillan..... PBR's... I believe have always had a Hogue overmold stock...
The HS would definately be better than the Hogue..
I have a FN PBR and I went with the McMillan A5 and have not had a bad day with it!! Everthing you want in a stock they have but I have never used a HS. just my 2c
