Almost immediately - I $hitcanned that thing from Ruger and installed a Spike's Dynacomp. Giant difference in the shooting of it. That little, light, 16"-barrel .308 bolt gun kicks pretty damn good. Enough that it takes you off target after a shot, and you can't see where/what you hit. It needs a muzzle device change, right from the factory, so plan on doing that right away. It takes a Torx T60 bit to get that damn thing off, and just go ahead and take the action out of the stock and block it into a vise - that Ruger muzzle device is on there pretty damn tight.
There's pics of mine with the Dynacomp installed somewhere around this site... I'll be damned if I know where they are, but they're here... <lmao>
