so, i've got a 10/22, and a low-level (under $200) nikon scope. after zeroing in my rifle, i decided to take the rest of the day off, and go home. when i got home, i proceeded to disassemble and clean my rifle, leaving the scope on. so... i have to zero it in again, right? well, i went to zero it in again, and noticed the base plate (?) (the thing on which the scope rings go) was loose. so i had to take off the rings, and tighten the screws sooooo, now i have to zero it in, again, right? also, will http://www.tufferbuffer.com/ this prevent/delay the loosening of the screws on the base plate?
