After putting together a measly 16 rifles my favorite caliber in the AR platform is the 5.7x28. A real eye catcher at the range and with a 20round magazine inserted after the top has been cut and the guts removed, there is no moving parts on the outside and the empty mag acts as a brass catcher. The real problem is I keep thinking I am going to set up an upper but find myself building it into a complete rifle before it is all over.
How do you feed from and eject to the same mag? I want pictures of this and a video of it in operation. Cause I just don't believe it.
