Christensen arms 4 in bottom picatinny rail - Christensen Arms 4 in Bottom Picatinny Rail

I needed a steel rail Christensen Arms and Optic planet both advertise this item as made of steel

I purchased the rail from Optic Planet assuming it was "as advertised" I cut the rail to fit a modification

I found out that the product is made of aluminum.

I contacted both the manufacturer Christensen Arms and Optic Planet both did not appear to be concerned about my issue,

Optic Planet would not give me any credit as I had modified the product
