This might be a silly question, but here goes. If I install a mil-spec tube (5 or 6 position) and replace the commercial tube, will my castle nut and plate work OK, or do I need to get the complete kit? Thank You! Bud |
Nope, different threads so they won't fit. You'll need a new lower too, one that has milspec threads.

Are you just kidding or what.....?
I know your joking, but don't joke like this. I get people all the freakin time asking for mil spec castle nuts  and milspec receiver end plates to fit on their "mil spec" lower receivers
|
no, the way the tubes are made are the reason they're different. The com tube is extruded, the whole thing. The milspec is forged and milled out |
no, it's because the mil-spec threads are rolled in (stronger) than the cheap way of threading them on a lathe (hence the larger commercial OD) |
