Cva Hawken 54 cal trigger spring

[milkman6748]

I had my trigger out to clean and figure out why the set trigger was not working. In fiddling with it the spring up front flew off. I heard it ping across the garage but for the life of me I cannot find it. Does anyone know where I can buy one of these springs pictured? Picture is taken from the net this is not my assembly it's just for reference.

TIA
