Build Your Own Or Buy Pre-Built?

There are benefits on both sides of this coin. So I’ll briefly outline some considerations of each method and you can decide for yourself which you like best:

Building Your Own


  1. The parts are interchangeable with its rifle counterpart and vice versa. If you already own the rifle, you can use some of its parts in your pistol build. This can help keep costs down.
  2. You can convert your AR-15 pistol into a rifle. With the right tools, an AR-15 pistol can be two guns for the price of one.


  1. Short gas systems can be tricky to get right. The platform was originally designed for a 24 inch barrel. If you use a short barrel, you’ll need to make sure that you use the right parts for reliability with a short gas system.

When building your own, you must also know which parts are most likely to fail. For your benefit, refer to Minuteman's detailed component guide.

Buying a Pre-Built


  1. Complete AR-15 pistols are surprisingly affordable. Although building your own is largely considered to be the cheapest route if you’re trying to keep the price down, these pistols are actually very reasonably priced.
  2. Complete AR-15 pistols are usually reliable. Manufacturers account for the shorter gas system and build their pistols for reliability. You’ll very rarely need to tinker with a complete project to get it to work.


  1. You may end up spending more on attachments and accessories. Since complete AR-15 pistols come in pre-defined packages, you may end up dropping a few dollars on parts to get your pistol configured just the way you like. Remember to consider this as part of the overall price.

If you decide to go with a pre-built , you’ll obviously want to get the best one.

Sig Sauer MCX Virtus Pistol

Our Best Model

Sig Sauer has long been a staple in the firearms industry.

Sig has an exceptional reputation for their pistols. Some of them have taken on legendary status. Sig has brought their pistol building expertise to the AR-15 pistol market with the Sig Sauer MCX Virtus Pistol.

Sig designed the MCX for absolute performance.

They started with their proprietary SB15 stabilizing brace to ensure that you can use the MCX in any context where a rifle might be ideal. This gives you a solid foundation for sighted fire, using any sights or optic you put on the MCX.

To complement the superb brace, the MCX also features Sig’s Matchlite trigger that provides a supremely smooth trigger pull and a clean break for exceptional accuracy in any shooting context.

The MCX utilizes Sig’s gas-actuated operating system that enables Sig to pack a rifle caliber into a more compact platform. The MCX also has an internal recoil system to reduce felt recoil and improve accuracy for multiple shot engagements.

Sig equipped the MCX with a free float handguard that features MLOK attachment points. MLOK has largely replaced the old picatinny rail system. The MLOK handguard enables you to attach any accessory securely and with less rail space.

The MCX comes at a characteristically high price point. This is fairly normal for Sig guns. But, the price tag gets you the ultimate model on the market right now.

Moving on.

There are also some challenges involved with getting a true SBR. The ATF has special regulations for any rifle with a barrel shorter than 16 inches or that is less than 26 inches in overall length.

So getting an SBR isn’t quite as simple as getting a full length rifle.

However, the ATF has no such restrictions for pistols.

That’s why we have these firearms.

An AR-15 pistol is essentially an AR-15 without a stock. Without the stock, the gun becomes a pistol, legally speaking.

The recoil of an it is manageable enough that the gun is almost perfectly usable without the stock.

But, there’s a remedy for this, too:

The arm brace.

Arm braces were originally created to help amputees shoot rifles one handed. But they are shaped in such a way that it makes them handy for use as an improvised stock.

With an arm brace, and this gun can be pressed into use for just about anything you’d use a rifle for.

Of course, this brings up a logical question:

If you’re going to use an AR-15 pistol like a rifle, why not just get a rifle?

That goes back to the ATF regulations.

Why use an AR-15 pistol?

There are three main reasons to use one:

1. You can get an AR-15 SBR without paying for the tax stamp.

Tax stamps can cost a few hundred dollars and often take several months to process.

In some states SBRs are entirely illegal. But even in many of these states, you can get an AR-15 pistol with a short barrel.

They are a great way to get legal access to configurations that might be otherwise too costly or illegal.

As always, check your local laws to make sure that these pistols are legal in your area before you buy or build one.

2. Interstate transport

An SBR tax stamp is only good for the state you live in.

So, even if you have an SBR tax stamp, taking your SBR to states where it’s illegal is still illegal.

But, if you have an AR-15 pistol, you can take your it to states where SBRs are illegal without much of a fuss.

This is handy for competition shooters or instructors who travel with their guns to out of state competitions or classes they’ve been invited to teach.

Now, there are some states where your firearm is illegal no matter what. So be smart about it, and do your research.

In any case, an this gun gives you more transport flexibility than an SBR, even with a tax stamp.

3. A short barrel is an excellent CQB or vehicle carry gun.

There’s a legitimate discussion about whether or not you need a CQB or vehicle carry gun. I won’t get into that.

What I will say is that an SBR is the most capable type of rifle for operating in tight quarters. It’s very common for military units to use SBRs in their loadout for urban operations where they know they’ll be operating inside houses a lot.

In fact, the only real benefit of a shorter barrel is that it makes the rifle more manageable when you have limited workspace.

A shorter barrel:

Reduces muzzle velocity.

Reduces maximum effective range.

Reduces your sight radius if you’re using iron sights.

But for CQB situations, these things aren’t huge factors. Shooting distances are short and maneuverability is a priority.

So, if you want or need a CQB or vehicle gun, an SBR is the way to go.

And, since SBRs are so tough to get, a short-barreled AR-15 pistol is the next best thing.

Something to note:

Even though an it is technically a pistol, you’ll still need the same kit as you’d use for a rifle if you plan to make it a CQB platform. Your CQB firearm should have:

A sling.

A mounted light.

The sling is to ensure weapon retention. The light is for target identification.

In the civilian context, extra magazines and other tactical gear are optional.

One last thing:

An added benefit of a short-barreled AR-15 pistol is storage space.

You can store or stage a short-barreled firearm in more places than you can fit a full-length rifle. So the shorter platform gives you flexibility for things like staging your gun for home defense.

Since a short-barreled AR-15 pistol is such a handy tool, that leaves just one question…
