Have not played in a year or so, (I was using A&K MK243) had lots of fun, but starting to get old(43 in two weeks

) and wanted to do a not so much in your face roll.
Could anyone give me advise on a solid base sniper rifle to start with. And yes I know I'll need to upgrade it.
Please everyone,dont be shy to give your advice.
ps budget is no big deal
