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. Your will receive the kit for your specific marker that you order which will contain the o-rings needed for that marker.

I purchased this kit to replace all of the O-rings on a Matrix 5, and while the color coding and nice size chart make the replacements as easy as possible; I didn't receive any size 13 or 7 O-rings, which are needed through various locations on the marker.An update on this review, I contacted Captain O-ring and received great customer service. They shipped the size O-rings that were left out of the original kits and all is well now. Thanks Captain O-ring.
