Nothing additional from the standard one for the most part. The 15MOA feature will give a bit more adjustment for shooting more than 100yrds. If you're not going to do that, you'll gain nothing. The Picatinny part adds additional slots for ring position but the scope itself has more than enough itself. You'd be spend $40 that just isn't necessary.
Funny to see ppl swear by the whole Picatinny thing mount their optics then move the scope. Better are the ones with dots where eye relief isn't as big of a deal. It's "tactical" so thus has goth abe better. :roll eyes: Have dozens of rifles with optics, 15 or so are 10/22 with various optics and I've yet to require additional slots offered by a Picatinny mount.
