i have recently bought a remington 700p tactical rifle and now im looking for a scope (tactical). im really interested in the leupold mk 4 pr 3-9 or 3.5-10 power my question is will this scope be good out to 1000 yds. im not concerned about having enough elevation cause i know it dont, that can be fixed with a tapered base. my main concern is theres no parellex adjustment its set for 150yds will this be okay.
