Your cart is empty.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.
Note: The product image associated with this item is a sample only. You will receive the kit for your specific marker(s) that you order which will contain the o-rings needed for that marker.

I was handed a bag by my neighbor who no longer plays paintball and said I could do what I want with the stuff. Lo and behold there was this silver and blue old electro marker in the bag. As I began to pull it apart it was apparent the marker was played with a few times, not oiled, and stored dirty. Well I started looking for the parts needed to replace the internals, and since the R6 E-force marker is simple, its mainly o-rings inside. After doing some searching I found Captian O-ring, and I can say there is a reason they call him the Captain!I got the kit and was able to match up the o-rings, install them and rebuild the marker. The marker has performed flawlessly for being nearly 15 year old marker! Well worth the investment and I can rebuild it again, worth every penny.

They are definitely orings and not cheap flimsy ones I would recommend this product if it works for your marker

Great O rings to keep around

I wanted to rebuild an old marker (Piranha GTI) and was struggling to find information about the required o rings, so this kit was super helpful. The o rings come in a zip lock bag with a card that helps identify the sizes and lists what size to use where, but no diagram, so matching these descriptions with actual o rings was a bit tedious. I included a picture that can hopefully help.Overall, a great kit, with one disappointment - it did not include the softer o rings recommended for the hammer and instead suggested using the same one as for the ASA.

My old paintball marker sat in my basement for 10 years. The o-rings had melted. After a rebuild with this kit it worked great. Even the orings for the regulator were included. Excellent Product. Thank you.

I had three paintball markers I was replacing all the o-rings for and there was plenty assortment and quantity, of o-rings, to find all the ones I needed
