Thanks for your sharing.

Wood, Cement, and Brick are the surfaces you can mount them too not a color of the rack.

If you tilt the guns a little bit side ways they will clear without touching the wall

I have several rifles with scopes on them in mine. Minimum distance to wall is still about an inch. Better piece of advice is to make sure you measure between the upper and lower rack very well, to ensure your shortest and longest barrels will all fit.

Yes

Yes, because you pick the spacing height. Place them on the wall accordingly. I have some spaced higher for rifles with 5-30x56 scopes and some spaced closer for things like my X95, PS90, Bren etc
