Rws model 52 rebuild

I rebuilt my Diana 52 and put a Vortek high power kit in it, its shooting at 23 ft/lbs.
it is also my most accurate and favorite springer.
if you are mechanical at all you should be able to do it yourself, just take your time.
If not, talk to Tom at http://vortekproducts.com
ask him what he recommends and who he recommends do it.
Jim at Precision Airguns & Supplies did my Beeman R-10, helped me do my Beeman R-7 ( I did some major rework on the R-7 as it had some major issues from the factory )
I did the 52 and my HW 77 myself
