Same details as the kit above. Includes the same items with the exception of a white bushing that slides on the rear spring guide- trigger end. Otherwise the installation is the same.
Only the full power kit has a steel bushing. This kit uses a thicker white bushing instead.
About 20% less cocking effort then the regular Pro Mac Kit.
Velocity is only down on average of 5% or so.
Still above factory FWB specs. Very high 700's to 800 fps in a good gun ( 7.9 gr)
Great for sub 5000 serial number guns as they tend to be harsh if sprung too hard.
But designed for any FWB sporter.
Spare springs to kit owners are available.
Easy to install
