Hey BPS, great idea on the tape. Never thought of that or heard of it. Great idea as to getting the right height measurement. I have done some work on N-SSA guns and new sights. Don't know why one of the guys didn't think of that trick before.
Didn't work on the stock yet, but know it should work. I'm basically a cheap guy and really want it to work so I don't have to go out and find a replacement stock. I just know it would cost me a bundle to replace!!!
