this has really got me. Every Savage bolt I've taken apart has a ex bolt at the end that lets you remove the guts. This Elite Precision only has a small button. No slot, no hex...nothing. How does this come apart? Here's a pic I've taken. If it's something simple I'll be very pleased to feel stupid.https://scontent-ort2-2.xx.fbcdn.net...64&oe=602B1D8F
