took mine to the range for the first time yesterday
Nova SP (ghost rings), with mag extension; great deal off GunsAmerica. Haven't noticed any rattle.
Only added the recoil reducer (girly man), which seemed to make a big difference over the time I shot Chaim's Nova.
With the GR at mech zero, I kept Remington RR slugs in a 4" bullseye at 25 yards, offhand, at the local indoor range.
Holy cow, this thing shoots.
Will take it out to 50 yards in the future when I zero the .308 on an outdoor range.
Would I be a nut for trying to bag a whitetail with a "tactical"
Nova?
Anyway, $299 new sounds just "OK." If it's not too late, I would check some of the online brokerages for good deals on a used one (I'm cheap that way).
I got mine barely used, including the ($50) mag extension and an Eagle detachable/covered buttstock shell holder, shipped from Tacoma WA to MD for $310 after talking the guy down (originally $310 plus $25 shipping). Then another $10 for my FFL, for a total of $320. (Another $75 for the girly-man recoil reducer & its mounting bracket.)
Otherwise it would have been:
$379 new (MD price)
$60 (mag extension, w/shipping)
$20 Eagle shell holder
