This is our new, updated version of the Rail Mounted Compensator base for the P80 PF940 V2. Based on our fans and customers suggestions and requests, we’ve made quite a few changes that have led to many improvements. Here’s a list of what’s changed from Mod 0 to Mod 1 design:


  • Reduced total number of parts and hardware from 4 parts/6 screws to 2 parts/2 screws
  • Integrated side clamps into the uni-body design
  • Redesigned add-on rail to act as timing device, to properly locate body to frame to allow for space between compensator and slide
  • Reduced base size from  .770″ tall x 1.145″ wide to .595″ tall x .975″ wide
  • Reduce overall weight from 2.7 oz to 1.6 oz (41% reduction)
  • Increased rigidity while decreasing volume & weight
  • Maintains compatibility with Mod 0 Compensator


The Mod1 base attaches to your frame utilizing the picatinny rail, sliding on with a tight grip. The Timing Rail properly aligns the base with your slide/barrel, secured using the 2x 4-40 3A screws. As the base is now timed, it leaves a small gap between the Compensator and slide, allowing the RMC to be used as a stand-off device. Much like the Mod 0, the lowered compensator shelf height allows for slides to be removed for cleaning without detaching the base assembly.
