Quoted: ... but what are the A1 or A2 FENCES on a pre or post ban lower? Doe the compatability of the upper and lower relate to the fence configuration?? Need some help here. Thanks. I am not expert at AR15s by no means, but I will take a stab at it. A fence usually means there is a little area built up around the magazine release button to HELP prevent accidental release of the magazine. I think A1 versions don't have it. It doesn't have anything to do with pre/post ban lower and upper/lower receivers compatibility. |

When I was in the army a had and saw plenty A1 with this fence. I believe the early one did not have them. My last A2 I had in the Security Police was a conversion. this did not have a fence.

A lot of the early M-16's (A-nothing, no forward assist) did not havve them. |
