When I built my first smoothie, I ordered a turtle front sight. 20 ga barrel is round, bottom of turtle is flat. I rounded out the base, but things didn't look right, anyhoo the 4 little feets stick out, the head sticks up. :cry: Still do. I know these must be pounded down to contact the barrel. But I fear the brass or g silver, whatever, don't remember, may break at the bend???? :hmm: Heat and bend down, will the solder loosen it. Any recomendations?? :: good pics to see what it needs to look right??
