Here is waht I posted on an other forum:
I have the basic Slavia 630. It is an excellent airgun. It is made of
quality material, real steel and wood. The quality of construction is
excellent, the finish is good, the blueing being not as shiny as higher
priced rifles.The stock made of hardwood has a somewhat rough
finish wich I simply polished with steel wool and a coat of linseed
oil over the varnish (I haven't remove the varnish just polish an aply
a coat of oil to protect and shine it).
The big plus is accuracy, .25 inch at 10 yards with Crosman
Copperhead wadcutter. Almost same accuracy from Ruko Match
wadcutter, both 7.9 gr.
Consider too: low velocity/power, maximum I chrono, 545 f/s for
5.1 FPE with 7.9 gr Ruko Match wadcutter.
Also I mounted a Bushnell 3-9X32 airgun scope on it with no problems
for compensating for a barrel drop, but the grooves on the receiver are
non-standard or Europeen standard (11 mm I think) so the mounts
furnised with the scope are rather wide open when clipped over the
grooves. If you can get the right mounts for it every thing should look ok.
But the combo is fully fonctionnal as is and I experienced no scope or
mounts movements, the rifle being very kind to shoot.
Last note, the rifle is best "balanced" with 7.9 - 8.0 gr pellets. Lighter or heavier ones cause more clang an twinkles.
I have mine for two and a half year and still appreciate it very much!
