Ask Foghorn: Is 300 Blackout a Good Caliber for a First AR-15?

Matt writes:

I am looking to buy my first AR. The biggest dilemma that is facing me is the choice of caliber. Obviously, the main stream choice is the 5.56/.223 but I am really interested in the .300 Blackout because of the larger size of the round and the perceived greater stopping power. The AR I am drawn to the most is the Smith & Wesson M&P 15 Sport because of the price and I am a S&W fan. That rifle compared to an AR in .300 is a difference of around $1,000 from what I have been able to find. My question is, do you think that it is worth the extra money for the larger round or should I go with the cheaper option? I plan on using the rifle for home defense and of course range time. Do you think that I should buy a rifle in 5.56 and then possibly at a later time purchase a .300 upper? I am not sure if this will impact your suggestion but I also plan on putting a suppressor on my rifle at some point. Thank you for your help.

Short answer: No. Let me explain . . .

Ask Foghorn: Where Have All The SCARs Gone?

Reader Nick writes:

Assuming that your FNH 3 Gun Team is a marketing tool for FNH to highlight their products, you might tell them they ought to disband the team – many of those products are unobtanium. No use spending sponsorship money when there’s nothing to sell. I’ve had a SCAR 16 on order at three separate distributors for 6 months now and none of them have any idea when they’ll be blessed with one from FNH. I’ll give it another couple of months and then I’ll just give up and move on to another platform.

The implied question — what’s with the SCAR shortage? And the answer is one that lets us blame our favorite scapegoat: the U.S. Government . . .

Ask Foghorn: Medical Kits for the Firing Range

 2011-06-20_23-22-43_805

Yesterday I talked about a med kit that’s being offered for sale that isn’t up to my standards. What followed in the comments was a pretty good conversation about the benefits of clotting agents, the appropriateness of duct tape and some really good suggestions as to what makes an “ideal” med kit for every day carry or to take to the range. Wanting to capitalize on that discussion, Dan asked me to write a quick article about what I’d include in a small, medium and large first aid kit. Here we go . . .

Ask Foghorn: Are Lasers Really Useful?

Reader Joshua asks (nearly a year ago now):

Can you tell me how useful a Crimson Trace laser system would be for a beginner?

A red laser sounds pretty cool. Green laser sounds cool too, but given physics, is going to have more powerplant issues, and buying batteries is annoying, and replacing them often is annoying. The whole option itself gets this new shooter wondering: how important is a laser sight at all? Is it a supplement for dark environs? Is it to make things easier in a chaotic combat situation, day or night? How hard are red lasers to see, how easy are green ones? . . .

Ask Foghorn: Eliminating AR-15 Wobble

 P1140237

Reader DrewR55 writes:

I have what seems to be a common AR issue. I’ve assembled a Palmetto State Armory AR-15 and the rifle functions perfectly well. But I have what is to me an unacceptable amount of play between the two halves and this bothers me every time I handle the weapon. I am ‘slightly’ OCD and the play annoys me to no end. I understand that this play does not affect the rifle in the least but it bothers so I aim to fix it. Especially because if I spend X hundreds of dollars I want it close to perfect as I can get . . .

Ask Foghorn: Staking your Gas Key?

P1240008

Reader Donald writes:

The one concern I have building [a bolt carrier group] myself is staking the gas key. I have seen a guy on Youtube do it with a $80 dollar tool but was hoping not to have to buy anymore tools for this build. What’s your thought? Can I stake it with common tools like a center punch or should I try and find a gunsmith to do it for a fee?

So, for the uninitiated, two questions here. First, what does it mean to “stake” the gas key, and what does it do? And second, is it a DIY kind of thing? . . .

Ask Foghorn: Meters v. Yards for Zero Distance?

courtesy chemistry.about.com

Jeremy writes:

I don’t know if you guys have gotten this question before, or if it would warrant writing an article, but do you have any feedback on zeroing a rifle on a range measured in yards, and then how accuracy would be affected when shooting that rifle estimating distance based on meters? The difference @ 100m vs. 100 yards is going to be about 9′ so my assumption is that even to the max effective range of a 5.56 round, there isn’t going to be enough of a difference to see a noticeable POI shift. Do you have an opinion?

Good news for the lazy among us: for the typical zero on a 5.56 gun, it doesn’t matter . . .
