Stock crawling is not a technique but a function of how you are built. A short guy with a narrow chest and short neck might need extension rings. For the typical guy, the regular rings work just fine. Just happens that almost any factory dimensions, rifle or shotgun come "readily to eye" for me.
The position of turrets and distance between ocular and objective bells also play a part. I have a nice German 1" Zeiss (long before Conquests) that has long bells and won't work on a #1 with standard rings.

As for the liar, welcher Bricktop, his day is fast approaching.
Coward trolls won't accept PMs.
How's the phantom "campfire" coming ?
