Definitely worth it. Lighter spring is nice, still hurts! Kind of similar to stock spring. Stronger spring is killer! Flew through a cardboard box no prob. I don’t think i’ll be taking a bullet from it lol.

A S. 5/5
As DZ's high-tier pump-action pro springer, the refreshed DZ Max Nitroshot+ MK4X is everything the original MK4 wished it could be. A blaster that's close to perfect, now made perfect! The prime is smooth, feeding is reliable, and boy, does it perform. The spring pack is a must-have, offering rough velocity tiers of 100, 200, and 300 FPS with each spring. My club is getting a chronograph soon, so I'll be able to provide more accurate numbers across both barrels, using six-shot averages. It's modular, powerful, and yes, it's a very large blaster. However, even at 300+ FPS, the prime is lighter than any NPX2 or Stryker Pro I've used. DZ now seems to have a pump-action pro springer available at nearly every price point. At $35, the NPX2 gets you the bare minimum needed to compete at around 200 FPS. The Stryker Pro offers more upgrade paths and a roller BCAR for $70. Meanwhile, the MK4X brings fully metal internals, a roller BCAR, greater modularity, and even more performance potential. At $110, it's a solid value, especially when compared to Worker's Swift and Harrier, which are similar in size, power, plunger volume, and internal build quality. Make no mistake: this is a premium product. If you're looking for the bare minimum to get yourself on the field, check out the NPX2 or Stryker Pro. However, if you're looking for the best money can buy, or want 300+ FPS with a surprisingly light prime through nothing more than a spring swap (yes, longer barrels via collets can get the NPX2 and Stryker Pro into the 300 FPS range, too), then splurge and get yourself a DZ Max Nitroshot+ MK4X!
