Product Details



These are BLEM PREs. There is a slight misalignment with the factory picatinny side rails on these. They are fully functional, they however do not align with the factory side rails and are therefore being offered at a discount.




Parker Mountain Machine is proud to now offer the PMM Picatinny Rail Extension (PRE) for both the SCAR 16/17 Weapon systems.


We took the standard M-Lok and Keymod Rail Extensions and redesigned them to match seamlessly with the FN factory picatinny rails at the 3, 6 and 9 o’clock positions.


The PRE has been CNC’d in-house out of T6-6061 aluminum and then hardcoated per military standards. The PMM  PRE is a low Profile and lightweight solution to mounting mission essential accessories on the SCAR 16/17. PMM machined additional vent slots into all of the picatinny rails to lighten the PRE and also enhance the rifle’s ability to cool-down after sustained strings of fire.


By adding a 2″ of rail extension to their standard or SBR length SCAR, a shooter gains the much needed space to extend their support hand while still maintaining access to the SCAR’s gas block.
