Liberty made 300BLK as I recallI have to wonder who built the integrally suppressed barrel combination as to if it has any value. I might be able to scrounge up stamp money is it well built, and gifted to me.
Much easier to sellA SBR/ SBS can be removed from the registry, but why?
Hell yeah why not I can shoot my 300 Whisper through it. If the OP wants to gift it to me I'd pay a stamp for an internal 300 Blackout. PM me some photos of the complete upper with internally mounted suppressor. If It looks good I'd adopt it.Liberty made 300BLK as I recall
