-------------------------------------------------------------------------------- I picked up a 20" chrome lined upper awhile back in a trade. The receiver is a key hole marked flat top with the white t-marks. I was told it was made by Cerro Forge. The barrel looks to be a medium contour has M1S HG 1-9 on it in front of the A2 flashider what doe's this stand for I know the 1-9 is the twist. It has a round free floating tube with a railed gas block. Do's this sound like factory built upper if so who do y'all think made it. Thanks for any help y'all can be. __________________ |
