Should I build 3 more ARs to use them? 
Stinking parts box is a bad influence on me…
I would if I could talk my wife into it.
M4C is the new Twitter.
Build one, pay it forward with the other 2 so someone else has an excuse.
If you leave them alone in a dark room with a few roll pins and an odd spring, you’ll have one in no time.
Should you start a thread about them? Probably not.
