Product Details

Parker Mountain Machine is proud to offer our redesigned M-LOK Rail Panel Heavy-Duty (HD) for both the SCAR 16/17 Weapon systems.

We took the standard M-LOK Rail Panels and redesigned them to withstand the rigors of battlefield environments by adding extra material and support structure. This guarantees that weapon accessories will not shear from your rifle if they are caught on windows, stationary objects, etc. during high-stress combat scenarios.

The M-LOK Rail Panels HD have been CNC’d in-house out of 6061-T6 aluminum then hardcoated per military standards. They are a low profile and lightweight solution to mounting mission essential accessories on the SCAR 16/17. The M-Lok Rail Panels HD are designed to compliment the PMM MRE-HD & PMM M-LOK Lower rail, which have also been designed to add additional durability in high-stress environments.

Product Features:

  • 2x PMM M-LOK Heavy Duty (HD) Rails Panels finished in either a Black or FDE 8625 type 3 class 2 industry standard hardcoat.
  • Mounting hardware and locktite 242 included.
  • An additional .050″ of material have been built into the M-LOK HD Rail Panels on each side to prevent shearing of weapon accessories.
  • Limited Lifetime Warranty.
  • Installation is simple using the factory intended 1913 Rail Mounting points on your SCAR.
  • M-LOK HD Rail Panels install in minutes with no permanent weapon modification.
  • Ultra lite weight/Low Profile design.
  • The only aftermarket SCAR Rail system on the market that utilizes a “captive” Front barrel bolt.
  • All PMM M-LOK HD Rails will work with any Magpul Designed Accessory or M-LOK “T” slot Style Mounting system using the Supplied PMM 10-24 x5/16 Mounting bolts.
