Lol, no tape i used flat piece of Wood for between Scope and Rail. After i used Fiberglas and two pieces of sheetmetal + Nut´s and Bolt´s to make it to one solid Piece. Reason why, cause i had this cheap scope for a long time and not used it and don´t wanted to waste Money for a mount that cost more than the scope and i also like building things ! Look doesn´t matter to me, as Long it works it´s good for me !!!
