| I recently put together a Nosveske lower, when I tested fired it I could hear a -for lack of a better term- springy “boing” noise coming from the buffer tube. For comparison I have a factory built 6920 which doesn’t make a noise at all. Spring, H buffer, buffer tube are mil-spec CMT, I think. Any ideas? Thanks |
