I seen a Saginaw slide with the angle top.On the bottom it is marked D-7161843 and under that is SG.I wasn't able to see what was inside the slide well,because it was a picture. I am not sure but I thought Inland and Winchester only made these slides or did they ship them to other manufactures. Thanks for any info you guys could give me
They are the only ones to use that type 6 slide BUT Inland had a contract with SG to make this slide for them as they were having some trouble making enough slides themselves as their production had increased so much. So your slide was made by SG for Inland's production of the M2 carbine.
