This comes of a NM rifle,it goes in place of the factory stripper clip guide and has a hole with threads on the left side for securing a scope mount? probably works with the Springfield Factory mount 2 screw design,I'm really not sure.
Was going to toss it but thought maybe somebody could use it.
If you know what it is please im me with info,I guess it might be worth.... make an offer.
I would love to trade for an M1A green sling if you have one.
