I just got my 3 rd upper in
I now have a del-ton 5.56 16" , DPMS 5.56 20" and a CMMG 22 upper 20" all 3 ar the A3 style noticeded on the Del-ton and CMMG I see what looks like an "F" stamped ion the side of the front sight and the CMMG looks like it has an "E" stamped in the front sight What does the letter mean? |
| The "E" is probably a forge code, while the "F" could either denote that the FSB is of the taller "F-marked" type, or it could be a forge code as well, depending on what side of the sight base it's on. Simply put: If the "F" is on the left side of the sight base, it denotes that the sight base is the taller type (taller sight post shelf). If it's on the right side, it's a forge code. |
