Dart Zone Pro MK-2 Low-Power Spring (90-100 FPS)

Excellent

Great for when you want to tone your mk2 down to kid-level. It's also super easy to prime now. Easy to swap out too - just need to take the slide off and compress the spring and bend it out.

Excellent customer service

Always answer my questions,fast shipping. What a great business.

Exactly what I wanted

So this was my first order from OOD and this is exactly what I wanted. I normally play games with friends and siblings who are younger and we will have a 100 fps cap and I love the ergonomics of the dzp mk 2 so I needed a spring to bring it down into that range and this did the trick. Super easy for natal just 3 screws on the priming handle and it was done. Thank you OOD, fast shipping and good customer service
