So I have a few options:

1) Buy a new 10 FCP-HS and get a blind mag when I really want an detachable box and add an EGW rail.

problem: Which EGW 20 moa scope rail? Round rear or Flat rear??

2) Buy a new 10 FCP-SR with the extended box mag I want and add an HS Precision PST114.

problem: Stockystocks website says that the PST114 WILL NOT FIT THE MODELS WITH THE ACCUSTOCK

3) Buy a new 10 FCP-SR with the extended box mag I want and add a Boyd's Tacticool stock I have one for my Mark II FV and love it

Problem: This stock is for a blind magazine and the FCP-SR has a detachable box.

I searched the forums for this info for awhile before posting, hope I haven't overlooked something.

Thanks,
Bobby
