Parker Mountain Machine P320 X-Comp

Parker Mountain Machine (PMM) is now offering their first custom firearm package – the P320 X-Comp. PMM mates one of their custom compensators with a P320 Compact slide and a X-Five frame. The result is a hybrid/integrated comp gun where the compensator nests almost entirely within the footprint of the frame. This combination of parts and features blurs the line between competition and full-size duty gun.


  • PMM Compensator: Our own single port design made of 7075-T651 Finished in a 8625 type 3 class 2 industry standard hardcoat with aesthetics to match the P320.  This design does not use set screws like most offerings, instead using a shim system similar to muzzle devices found on rifles.
  • Custom compact slide: With added ports to the slide to bring down reciprocating mass and added “X-COMP” and “PMM” markings for a distinct and identifiable look, this system utilizes a factory recoil spring  and factory slide internals, keeping the known reliability of the weapon.
  • Apex Trigger: we have utilized the Apex Tactical action enhancement trigger kit and flat face trigger.  This results in almost no take-up, with a crisp break and short, tactile reset.  
  • Custom stippled X-Five frame: With forward reference points and 360 degree coverage, this frame has a “mild” texture with more traction than factory.
  • Available with an RMR mounted and zeroed or factory suppressor sights with a cover plate for the optic cut (both options will come with a cover plate)
  • All PMM X-Comp pistols will come with a test target proving zero and accuracy.
  • x4 21 round magazines included.

Parker Mountain Machine Ruger PC Carbine M-LOK Rail

Parker Mountain Machine’s (PMM) new M-LOK Rail will likely be welcome news for many Ruger PC Carbine users. Ruger got a lot of things right on the PC carbine but unfortunately, the integral light rail isn’t one of them. The original light rail places many popular lights right up against the sling stud, if they even fit at all.

PMM’s Ruger PC Carbine M-LOK Rail completely replaces the polymor forend that comes standard on the Ruger PC Carbine. The machined aluminum rail is longer than the factory hand guard and features 5 M-LOK slots at the 3, 6, and 9 o’clock positions along with 4 QD sling swivel sockets. It hard anodized.

Parker Mountain Machine (PMM) just put the finishing touches on their SCAR 16/17 M-LOK Rail Panels. These low profile aluminum panels are drop-in replacements for the side and lower Picatinny rails found on the SCAR’s original hand guard. The panels make your existing SCAR hand guard compatible with Magpul’s M-LOK accessories.

PMM also make KeyMod versions of these panels for those who prefer that attachment system.
