"Much better than stock spring guide. My P90 one was made of clear cheap plastic with bubbles and did not have a ball bearing. This allows the spring to move around while the piston is cycling which lowers the chances of a spring snapping. Also, due to the free movement of the spring it may help increase rate of fire due to less resistance. I think it's great! It fit in with no problems.

"I got thisfor my KA P90 Version 6 gearbox. A slight problem... The tabs sticking out the sides are too thick, and wont slide down into place properly. The tabs on the stock guide measure 1.5mm with digital calipers. This guide measures 2.0mm, and the clearance hole measures 1.7mm. It hits the back of the piston guide. I can modify it to work. But if it says "(Version 6/7)" it should work with a version 6 gearbox.. Just saying. Now, as for the rest of it, the bearings are so smooth its crazy. Not only does the back spin.. but over 80% of the shaft spins as well, excluding the tip. That is the main reason why I haven't sent it back, I will make it work. I give 3.5 stars because it didn't just fit in. If it just dropped into place 5 stars for sure.
