"M.F.R." marked on Olympic lower . . . .

Gents . . . .

Anyone know the meaning of this marking?

I can't find it in the Blue Book.

Thanks much for your input, --Jim

MFR, which stands for Multi-Functional Rifle, replaced AR-CAR as the Olympic Arms brand came into use and continued until September 13, 1994.

Many thanks, GWP, many thanks . . . . .
