AR-15 Dents Primers – Is It Broken?

Ammoland covers the following.
I had never seen the Viking Tactics LUSA front Sling Adapter.
Which one do readers like the best, and what are you running?
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.
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).
I had always wondered how easy or difficult this would be. It looks like it just requires some basic tools and a little patience.
I especially like that they got a gunsmith to explain it, and he provided pictures.
Whether a product is worth the price, recall from Mike Vanderboegh, depends upon what it can demand on the market. DD can demand this kind of money, and thus, they are worth the money – to a least enough buyers to keep them in business, and expand their business to become one of the largest AR-15 manufacturers in the game.
Most importantly, the new M16A1 came with a cleaning kit, lubricant and an entertaining field manual, drawn by Will Eisner, the former Army comic artist who designed vehicle manuals in World War II. It was called “The M-16A1 Rifle: Operation and Preventative Maintenance,” otherwise known as “Department of the Army Pamphlet 750-30.”

The comic was easy to read, entertaining and — above all — a familiar look to American GIs in Vietnam. Many of them would have been familiar with “The Spirit,” a comic about a Batman-like masked vigilante he created before the United States entered World War II.
By 1968, more American troops in Vietnam began to accept the use of the rifle as malfunction incidents decreased dramatically. The powder used in the 5.56 cartridge was upgraded to reduce the fouling of various parts of the weapon. By 1969, the M16A1 was fully accepted as the standard infantry weapon for the U.S. military.
I’ll bet if you had an original of this it would be worth a lot of money.
Combined with the current military M855, or even better the Designated Marksman “Match” ammunition, the M-16 platform can take us well into the new century. The military has decided just that by declaring that there is no reason to adopt any of the new weapon systems anytime soon. There are special units deploying ACRs (advanced combat rifles) but their chance at widespread use anytime soon appears to be zero.
Personally, I have tried most of this new generation of rifles and they are just bigger, bulkier and more complicated. Some are just downright ugly! I would take an M-16 style rifle over any of them.
Surprising to many, the “AR” is about 65 years old, older than almost everyone reading this, and it is still going strong. It is our longest-serving service rifle of all time, by a large margin, and every year it just increases that lead.
Almost every other country in the entire world has adopted the cartridge of the M-16, if not the entire M-16 itself, and those that haven’t basically copied it.
For a rifle that so many people supposedly hate, it has completely dominated the world. I am happy to be a fan and user of the “Black Rifle.”
I’m even prouder to be a citizen of the country that designed, adopted and fielded it with such success.
While I’m not a fan of the green tip ammunition, this is a fairly well-informed article and has good history as well.
