| Is Busmaster using barrel extensions that have M4 feed ramps or not? |
| I'm looking at the 20" A2 Gov't profile barrel assembly. Last time I used one of their assemblies they did not use the M4 extension, however, nowadays it seems like most manufacturers do use them. Normally, it wouldn't be as big an issue, but I already have an upper for a build and it does not utilize M4 ramps. |
