Hey guys, I have a question about the buffer and buffer spring in relation to a Magpul UBR stock.
I have a "H" stamped buffer in my AR... assume this is a Heavy buffer correct? I don't even know what kind of spring I have. How can I tell? I bought a UBR stock and installation says I have to have a carbine buffer and buffer spring. I'm not sure what I have... My AR is a factory built Daniel Defense DDM4V2 if that helps. |
