Ask Foghorn: How To Build an AR-15 Upper Receiver


Daniel writes:

I was reading (Nick’s) post on assembling an AR lower assembly. It was awesome and the associated video answered all my questions and was done very well. All fan boy aside, I was wondering if he could do one for putting together an upper.

I’ve been avoiding doing this one since putting together an upper receiver can be a real pain in the butt. It requires some tools which I don’t have readily available (and probably wouldn’t work in my apartment), but thankfully Tyler Kee offered to give me a hand and show me how it’s done over a few beers in his garage.

Ask Foghorn: Best Route to SBR?


John P. asks:

What is the best approach for an NFA newbie to make a Form 1 SBR? Is it better to start with a rifle, obtain the stamp, and then shorten the barrel? Or should I prefer to start with a pistol and, once approved, add a stock?

I’ve done it both ways now, and as with most things the answer is “it depends.”

Ask Foghorn: SIG SAUER MPX Versus CZ Scorpion EVO 3 S1


Reader Eric writes:

You guys have reviewed the new CZ Scorpion and the SIG MPX separately. Is there a chance you could do a direct comparison between the two? That would be awesome.

I reviewed both the SIG SAUER MPX and the CZ Scorpion EVO 3 Pistol, and while I think I’m an impartial judge of the two guns I wanted to take that a step further. Following the release of these two guns, Jeremy S. purchased a Scorpion and I purchased my very own MPX. So I asked Jeremy to join me in a quick head-to-head review representing the Scorpion side of the argument, and I’ll be handling the MPX. Let’s get ready to rumble! . . .

Ask Foghorn: What Barrel Length for a 300 AAC Blackout Rifle?


I get a lot of questions like this and figured that rather than responding to one specific email I should put it out there for other people as well. Reader Pete writes:

Hi Nick, I live in Amarillo and really enjoyed your article on your 300 BLK build. Appreciate so much your sharing of experience so that I don’t have to go through all the same trial and error. I have 2 Colt M-16s that I’m going to convert to 300 Blackout. Had a few questions for you if you’d be so kind as to give me a bit of advice . . .

The #1 Most Important Upgrade for Your New AR-15


There’s little doubt that the AR-15 is the most popular rifle design around. Everyone seems to have one, and while the design is solid it can definitely be improved. As a 60+ year old design it has aged extremely well, but there’s one specific improvement that can be made to the average AR-15 pattern rifle that costs less than $50, is easy to install, and yet can make all the difference in terms of the accuracy and usefulness of the firearm. What is this improvement I’m talking about?

Ask Foghorn: Short Stroke Versus Long Stroke Pistons


The piston-based operating system has long been the gold standard for firearms design. Sure there are other methods like roller-delayed blowback and Blish lock designs, but nothing really stands up to the simplicity and raw reliability of a piston. The AR-15 rifle was originally designed to use a “gas expansion” system for operation, but these days more and more people are getting into the piston game. I’ve had a couple people ask me the difference between long and short stroke pistons, and so here’s the long and the short of it . . .

Ask Foghorn: What’s The Difference Between a Muzzle Brake, a Compensator and a Flash Hider?

I was sitting around with Kevin Brittingham and Reed Knight talking about gun stuff and one of the things they agreed on was a mutual annoyance at how people don’t use the right word to describe the thing on the end of their muzzle. Heck, even some gun guys don’t really know the difference. So, at their request, I figured I would write a quick article trying to explain the difference between the three main muzzle devices in use today . . .

Ask Foghorn: What’s TTAG’s Relationship Like with Gun Companies?


Reader Shea writes:

Nick, I have a real love/hate relationship with your gun reviews.  On one hand I love that you are not afraid to be honest regarding how you feel about any particular weapon.  You are so quick to call out a gun for what it is and even more importantly what it isn’t.  That being said I have fallen in love with several guns in the past due to their reviews in other publications only to have my dreams of obtaining the perfect piece for a given application squashed due to your brutal honesty of how the manufacturer of said firearm has fallen short. My question for you is about the nature of your relationship with the manufacturers. . .

Ask Foghorn: Perfect Handgun for New Female Shooters?


Reader Christian writes:

So I’m trying to get my very petite Fianceé into shooting. She’s 5′ 2″, and weighs 100 lbs soaking wet. The term “waifish” comes to mind when describing her. So the .22lr is about right for her, since she has small hands and isn’t particularly strong. I happen to agree with you that shot placement is far more important than caliber size, so I’m looking for a small caliber pistol to be her “go-to” piece if she needs it.

Ask Foghorn: What Does +P and +P+ Mean?


Reader Randall writes:

While I’m not exactly a newbie when it comes to *using* firearms, I am a newbie gun *owner*.  And now that I’m in the position of purchasing ammo, I’m finding things to be rather confusing when sorting out all there is to be had. I have Nick’s “Getting Started with Firearms” Kindle book, but it doesn’t really address the topic. How ’bout an article for us newbie-types explaining what’s +P and +P+ and all those others?

Good question. This area of ammunition, the +P and +P+ stuff, can get a little confusing and a tad dangerous . . .
