Were the 'SMG' marked 635's (9mm) built on A1 or A2 type lowers?
I haven't been able to find a wealth of marking or SN information on these. Thanks |
| My original 635 upper was black anyway. I bought two of the blems, one black, one grey, intending to SBR the black one - I ended up selling the whole thing a couple years ago when things were tight. I still regret it. The grey lower is now holding a 6933 upper built as a pistol. |
