Xcaliber offers a AR15 20VarTarg Barrel

[Russell]

I see that Xcaliber offers a AR15 20VarTarg Barrel. Sounds like a fun project and I wonder if the magazine would have to be modified to feed the 20 VarTarg cartridge correctly.

Should work.


Sounds like the 300AAC uses a standard AR5.56 magazine.
