About this item

  • O-rings are color coded by size, eliminating the headache of matching up sizes.
  • Included color/size chart helps with your first time rebuilding your marker. After that, just replace orings by color when it comes time to rebuild again.
  • All of the o-rings you need to perform a standard rebuild of your marker three times (other quantities available).


Your marker can fire thousands of rounds every week, puts up with the beating of countless rainy Sundays, and withstands a number of slides through the dirt and mud. Through all of this, you still expect your marker to perform week in and week out. A small bit of maintenance is key to ensuring that your marker functions and performs at its best. One major aspect of marker maintenance is replacing your o-rings. The o-rings in your marker wear down over time by withstanding thousands of cycles along with coming in contact with dirt/debris. Our kits provide an easy and inexpensive way to keep your marker in top shape by swapping out your o-rings. Use our exclusive color o-ring schematic guide, which shows drawings of your marker showing what o-rings go where. Rebuilding your marker couldn't be easier! Color o-ring schematic guides can be viewed/saved on our website as well as in this items product images. Note: The product image associated with this item is a sample only. Your will receive the kit for your specific marker that you order which will contain the o-rings needed for that marker.

Exactly what I needed! Rebuilt the whole marker with this kit (lpr, hpr, bolt) and works great! Only oring I noticed missing was the internal asa oring (004) but most will not need that one

The o-rings did not work well with my DM8. They didn't feel like the real thing.
