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 . . .

Ask Foghorn: Do Indoor Ranges Pose Health Risks?

Matt writes:

I’ve gone to different indoor ranges because I like to rent and shoot different handguns. I can see the fans going, they all say they’re safe. But no matter where, after shooting 200 rounds or so I feel like I smoked three packs of cigarettes. My throat will be hoarse, eyes bloodshot, and I will feel a bit sick. A tissue rubbed in my nose will show powder residue. That’s f’ed up. I also noticed that after spending time at an indoor range, I get headaches like those I got after playing football in high school . . .

John writes:

How about some Information on why there is NO ammunition available? Is it a Govt. conspiracy? Just a “Normal” shortage? How come Wall mart, Cabalas, On line dealers, etc has NONE? It sure would be nice if TRUTH, gave us some believable answers, you could ask Manufacturers, WHY , WHEN, & HOW MUCH WILL HIT THE SHELVES

No, this isn’t a normal shortage. We’ve seen something close to this before, but it’s never been this bad. Here’s what’s going on . . .

Ask Foghorn: What’s the Difference Between 5.56 and .223?

Ryan asks:

Hello, After reading the reviews on the Smith & Wesson MP-15 from your site, I went and got one. I was torn on which make and model to buy. But your reviews and other info I got sealed the deal. I have one question concerning ammo. I was always under the impression, that what ever was stamped on the barrel was the only caliber to be fired through the gun. Mine is clearly stamped Nato 5.56 there is no stamping that it can fire 223. I was told when I bought it, that it can fire both 5.56 & 223. I hear different tales on what is right and or wrong. Please help clear the air for me.

Believe it or not, I get this question a lot. So let me lay it out for you . . .

Ask Foghorn: Zero Distance for 300 AAC Blackout?

P1070145

Seth writes:

What are you using for zero distance for your blackout? I am big fan of the 50/200 zero in .223/5.56 and I am hoping there is something similar for the blackout round. I did a little experimenting on trajectory software, but didn’t come up with anything concrete.

The good news is that the old 50 yard zero works pretty well for 300 BLK as well. Here’s why . . .

Ask Foghorn: What’s the Best Polymer Handgun?

 

JoshinGA writes:

Im in the market for a new full size polymer gun, probably in a 9mm. What would you recommend for a polymer duty gun? Thanks.

Funny you should ask, I was planning on doing an article on this very topic. Which is why I rang up the manufacturers of the top polymer framed handguns in the United States and asked them all to send me one. So, which is best? . . .

Ask Foghorn: Best Rifle to Buy During an AWB Scare

Jeremy writes:

I figure everyone should probably own at least one rifle, shotgun and handgun. I’m hoping you can recommend something for me based off my needs, the current political climate and budget.

In particular, I’d like to get something that I can get now, but maybe can’t get later (esp. ammo) but can also be used for target shooting as well as hunting in case I go someday (and I would eventually like to do so). I like the idea of long-range shooting (maybe even some day up to 1000 yards) but am mostly concerned with sub-500 now. I really like the bolt action stuff but figure that will probably be available for a long time so am looking only at semi-auto stuff at the moment. A friend recommended an FNAR 308 Winchester.

There really isn’t a whole lot on the market right now, but you have options.

Ask Foghorn: What Parts Should I Use when Building an AR-15?

Many, many many readers have written in over the last couple weeks asking roughly the same thing:

I was reading your article on Best Budget AR 15 and I tried to click on the build recommended links but most don’t seem to work now. Do you have an updates? or suggestions? I am very interested in learning more and trying to build my own.

So you want to know what my build list would look like these days? Let me knock you up a list . . .
