Upgrade Spring for X-Shot Pro-Series Longshot – CQB Performance

This spring is specifically made for the X-Shot Pro-Series Longshot! This CQB Performance Upgrade Spring is a great option to upgrade if you have the 8+ version of the Longshot, or a great option for a lighter prime if you have the 14+ edition of the Longshot. The CQB Performance Spring is about 15% weaker than the stock 14+ edition spring. With the Metal Plungertube this leads to a decrease in FPS according to our testing. However, when used with the stock plastic plungertube it can achieve performance similar to the stock 14+ edition spring. These upgrade springs are made from High Quality steel and have flat grounded ends, so they apply even pressure to the plunger.
