| Noob here. I am thinking about building a AR chambered in 7.62x37. Can I use a 5.56 lower or do I need to make sure I get a multi lower? |

Welcome the the disease-infested dark side. The caliber on the receiver isn't anything legal –– only the serial # matters. Your standard receiver will be just fine. I also have a 7.62X39 built on a .223/5.56 labeled lower. Watch out for magazines! There are very few that will feed the 7.62X39 round reliably. I bought a ProMag and it required mods to work at all. I now have three ASC mags that are flawless.
ETA: [Edited To Add] You'll also need a different bolt [standard bolt carrier] and an enhanced firing pin. My barrel came with a matching bolt and I got the firing pin from Model One. |
