What makes a carbine length and midlength? How would you turn a carbine length into a midlength?
Not a smith, but I think it has to do with how the gas works to cycle the bolt. So in tossing out a guess that it's the size of the gas port hole is.
For an LW gas piston though I'm not sure that works the same.
The gas port location is the difference.
Midlength means that the port location is some where between the carbine and rifle gas ports holes. This is dependant on the mfg. preference for the location.
I don't believe there is a standard. Someone else may be able to answer that.
The gas port for the Midlength (on LWRC's) is approx 2" further up the barrel (towards the muzzle end) than the carbine model.
I don't think you can make a carbine length into a midlength.
The carbine port would have to be welded, then you run into barrel integrity issues (Kaboom) when you try and perform this.
To go from one to the other, have the barrel changed to the configuration you want.
