Quick question about upgrades, ok well im new here im a big fan of snipers and im a huge fan of the M40A1 MC sniper. But im new to getting out there and shooting and what not. But i have my grandfalthers remington model 715 bolt action rifle. And i would love to make it a gun i can go long range shooting with target practice at ranges like 400-800 yards on torso size targets. Its a remington 715 in 300 win mag takes 3 round long action mags and has a 24in barrel and also has a tasco pronghorn $30.00 scope on it sighted in to 100 yards. Now i would like to make a couple upgrades like a new scope such as the Bushnell Elite 4200 6-24x50mm Tactical Rifle Scope http://www.snipercentral.com/bushnell4200.phtml OR Weaver Tactical 3-15x50mm http://www.snipercentral.com/weavertact.phtml . And i got a little nervious watching the news thing about the remington 700 factory trigers so i would love to change my factory triger in for a remington x mark pro triger but im not sure if thats even possible. So i would like to no if the scopes are any good for what i want them for and if it is even possible to put a x mark pro trigger in my gun ?
