These two look the same, but CDNN is telling me it won't fit the Saiga? Looks like the same item but quite a bit difference in the price.
CDNN unit $29.99:
QD mount CDNN
Gilberts unit $42.95:
QD Gilberts
I would like a QD unit, and would like to save some money if possible. But would rather spend the money to get the better quality and better fit if they are different. Picture looks identical as well as the description.
