If you have a Polymer80 PF940SC build that's a bit rough and being funky, you might need this smoothly machined replacement part from Rook Tactical!
Locking Block Rail Upgrade from Rook Tactical is a precision-machined from proprietary steel, a definitive upgrade from the MIM (Metal Injection Molding)
part that comes standard with the P80 kits.
This front rail will fit PF940SC frames ONLY! Will NOT fit GST-9 models!
