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. 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.

Mine was missing the 2x16mm o-ring. The firebolt wouldn't seal properly when i tried the thinner o-ring either, so i had to order others.Also, they mislead with the title of 3x set -- I might have received 3 of each size o-ring (besides the 2x16mm which was missing entirely), but a single complete rebuild requires the use of multiple o-rings of the same size. So you can't actually rebuild the entire gun 3 times -- rather, you can rebuild the gun once, and replace select o-rings 1 or 2 times after that.

Terrible product. I usually don't write reviews but this one really got me annoyed. This kit didn't have the most important o rings needed to rebuild the gun and it had a ton of extra random super large orings that did not have any place in this gun at all. A complete waste of time and money.

I rebuilt my marker with these and had major air leaks! Try another brand, very dissatisfied with the Captain O-Ring product.
