"A direct drop-in for my CXP UK1 Captain. I use this to switch to a M110 spring for CQB. Sure, the system already has a quick-change spring function. But for a few bucks more, I get the full upper gearbox assembly and don't need to use tools to swap.

"Fits perfectly, works gear. I got an extra for my ICS MARS Komodo so I could quick swap uppers at fields that have different FPS/Joules limits. This upper was shooting 440 out of the box, I lowered it to sub 400.

"Works as described. The quick spring guide is great. Makes swapping springs to fit the different field limits easy.
