| So I'm kicking around the idea of putting together a dedicated upper. I'd like to use a Spike's bolt... but Spike's doesn't make a barrel I want. So, what I need to know is whether a Spike's dedicated bolt collar will fit on, for example, a Model 1 barrel. Seems like the Spike's/CMMG/Ciener bolts are the same; are the barrels standardized? |
