Highpockets...
Someone spent a bit of money to put it together that way from the original factory configuration. Change anything you don't like, and keep what you do. If it's the way you like it...then you scored a great find!! You didn't have to mess with it to get what you wanted!
It's only more desirable to someone who wants their rifle set up that way. If you're happy with it... It sure beats having to source all the aftermarket parts and do the work yourself... You get the benefit without the hassle!!😁😁😁
