I get the feeling that not everyone understands what a picatinny rail is. It's nothing more than a weaver base with slots that are wider, and placed at fixed intervals along the rail. The width of the slot allows you to use rings that have a much stronger ring to base interface. The fact that these slots are along the entire length of the base guarantees that whichever scope you mount to the rifle, it will be able to be mounted with proper eye relief for the user. Although you can purchase any configuration that suites your fancy, picatinny rail does not automatically mean that you're adding anything forward of the receiver. This short article explains the difference. http://blog.cheaperthandirt.com/weav...catinny-rails/
