Holes Under Butt Plates, Help Needed

[jimb16]

Understood! Now that I have a "complete set " of both carbines and M3 trench knives, I'm going to have to be very careful and discrete if I bring home any variants or line outs. One by each maker just isn't enough. I already have 2 NPMs and 2 Inlands in the carbine group and a couple of Utica and Imperial M3 variants as well as all variants of the Case M3s. And I'm afraid I might get hooked on M4 bayonets too since I already have the A.C.C. , AERIAL and Case. Plus I'm up to 4 Garands....
