  7. What is the difference between an 18 and 20 round square head magazine?

    The 18 round magazine is the first 18 round magazine on the market to continually and consistently feed 18 rounds. The time tested rotating channel inside allows First Strike to feed consistently without adding fin pressure that can damage or flip your First Strike rounds. 

    The 18 round magazine uses a high tension spring to exert more force on First Strike rounds. This is necessary because you will often run into flashing or burring on the fins of the round from the manufacturing process. In order to force the rounds through the magazine, a higher tension spring is required. 

    Due to the higher tension spring, it is recommended that you use a harder shelled paint in the 18 round magazine if you are not using First Strike rounds. We'd list off suggestions, but availability changes based on regions so we can't say what is best in your area. 

    The 20 round magazine is designed solely for the use of standard paintballs and has undergone over 8 generations of revisions to earn the title as the most reliable paintball magazine on the market. 

    This magazine holds 2 extra rounds, and has a lighter spring than the 18 round magazine in order to ensure reliable feeding with a variety of different brands and grades of paintballs.

  8. How do I know if I have a warranty?

    The user manual for your MILSIG marker outlines that all markers carry a 1 year parts and labour warranty from date of original purchase. This warranty covers parts and workmanship that stem from regular usage.

    Physical damage is not covered under the manufacturers warranty, but will be assessed on a case by case basis to determine the best courses of action. 

    Please note that Warranty is covered within the country of purchase ONLY. If you have purchased your MILSIG marker from a source outside of Canada, you will need to return it to your vendor to be serviced.
