A very cool and informative video if you care how things work and how to troubleshoot them.

How To Build An AR-15

BY Herschel Smith

Brownells has done something really good. They’ve put together a comprehensive series on building an AR-15.

The full series is here, and I see that it includes a list of tools necessary for completion of the work (although I don’t know why it’s well into the series before you find this).

Mike Gover discusses it. While I like that he mentioned Kyle Lamb, I was under the impression from prior reading that the specops guys had essentially learned that grip from the gaming community, and then passed it down through the ranks. Someone can correct me if I’m wrong.

I had never seen the Viking Tactics LUSA front Sling Adapter.

Which one do readers like the best, and what are you running?

AR-15 Zeros And Trajectories

Via WRSA, this thread at AR15.com is great. Thanks to the guy who worked so hard putting this all together.

I got it all the first time around (make sure to study all of the graphs and read the discussion carefully). If you’re unaccustomed to working with Newtonian physics, it may take you a time or two through it.

My complaint: He addresses only 55 grain bullets, and doesn’t seem to make much of barrel length. I’d like to see this thread expanded to include 68, 75 and 77 grains. A lot of guys are shooting heavier bullets now. That affects velocity, and thus changes everything.

But that’s a minor complaint. To be sure, I haven’t put together anything like this for readers, so I have no room to complain. I’m sure he put an awful lot of work into this, so he doesn’t need complaints from the peanut gallery.

Cops, AR-15 Maintenance, And Body Armor

BY Herschel Smith

A few odds and ends.

Via David Codrea, cops kidnapping children. Yes, seriously.

How to remove an AR-15 trigger group. Now do one on proper installation.

Removing an AR-15 barrel nut (hint: he heats it with a torch).

Rex reviews some really, really light Level IIIA body armor. Yea, it’s not good for rifle rounds, but it’s significantly less expensive and you’re protected against the most probable shot (and more likely to wear it given how light it is).
