"I drop this in my vsr 10 gspec and it shoots 549fps.

It is the only mod I did.

"This does not fit the stock cylinder of the Well MB03. The inside wall of the stock cylinder is too small for the piston. Piston must be modified to fit. Its best to get a complete cylinder and piston at the same time.

"Well it is a very nice set and is practically a drop in replacement however a small amount of sanding is needed. I have a well mbo3 and I sanded the piston itself down a hair with some 1000grit sandpaper and now it’s a good fit. A lot of people were saying upgraded Sears were needed so I purchased them but didn’t install them just to see how the stock ones held up and so far they look the same as before. Maybe I got lucky with a good set or well makes better sears but so far so good. Also it definitely shoots way harder and it sounds a little more aggressive too which I like. My buddies I play with are terrified of it now. I also added a tight bore barrel which helped even more with power. I’d recommend this product. It’s literally a drop in and if not it takes 2 minutes of sanding to make it perfect. I highly recommend this product
