Modern Riflery: Create Your Own Combative Carbine

AR-15 carbine combative rifle

While I don’t consider myself a “rifle guy,” I believe every American should be a rifleman. The concept of every citizen having a rifle, and knowing how to use it, might be the ultimate homeland security. Thus, four to five times a year I break out my AR-15 and practice.

When I took an interest in the AR in the late 90’s, I bought several and started a training journey. Along with an armorer course, I went to Thunder Ranch, Gunsite, Blackwater, Tactical Defense Institute and took classes from several traveling trainers.

The author’s combative carbine is as compact and sleek as possible. Accessories have been kept to a minimum.
Today, I have narrowed my multiple carbines down to one and it’s set up just for me. It’s as compact as possible, light weight, sleek, and easy to maneuver. If I were still on the job, my cruiser carbine would be set up much the same way. I can hit reliably from contact distance out to 300 yards using my chosen 75 grain Speer Gold Dot soft point ammunition, so I feel I have my likely needs covered.
The primary reason for the combative carbine is to have a gun with greater reach and precision for the atypical law enforcement or personal defense situation. The faster the threat is neutralized, the better.
The AR-15 rifle can be “dressed out” however you like, but never rely on gadgets for performance. You can’t buy skill so don’t try. As a rule, an AR setup for combative (not necessarily military) purposes should have . . .

• An optic
• Back-up iron sights
• A sling
• A mounted white light
• A muzzle brake/flash hider

Additional items may make your carbine unwieldy so think carefully before adding other toys. I prefer the AR-15 platform because it offers continuity of action with the semi-auto pistol. It has a pistol grip, a push-button magazine release, a “slide action” that can be manipulated with the support hand and the ability to clear stoppages quickly.

I prefer 20-round magazines. As I have a light, sleek gun, why add a big hook at the bottom? I also like the idea that I can reload it like a pistol. I can get the palm of my hand under the magazine floor plate and “heel it” into the mag well, much like a pistol. I’m not holding it like a soda can and having to push-pull to make sure it’s seated. I also think 20 rounds will handle all but the most extreme problems.

Spaulding at the Surefire Institute with a suppressed AR-15. While the gun is certainly quieter, it’s also longer and less maneuverable.
Controlling the recoil of the two systems is also similar by putting body mass behind the gun to keep the muzzle on target. Getting “behind the gun” isn’t the same as sticking your butt out. The carbine’s recoil is more “rearward linear” than a pistol as the bore of the AR is actually in line with the stock while the pistol sits above the hand. Having the bore in line with the shoulder makes recoil control even easier.
Combat level speed and accuracy are achieved by squaring the body behind the gun. Many shooters want to blade their body due to the gun’s length, but it’s a mistake. Think of it like your upper torso as a gate, when the gate is closed, it’s locked in line with the rest of the fence. If the gate is left open to swing, it can be moved with little effort.
Keep the shooting hand high on the pistol grip as it keeps the hand in proper alignment behind the trigger for better trigger control. If the standard grip allows too much index finger to enter the trigger guard, get a grip that adds material behind it. Also, by pulling back on the grip, the gun is better locked into the shoulder, increasing control.
The obstacle course at the Tactical Defense Institute — shooting from non-conventional positions is an important part of preparation. 
Grip the forward hand guard firmly with the support hand, which differs from shooter to shooter. Some prefer to use a vertical fore grip while others don’t. When using a vertical grip, don’t grasp it like holding a drink glass. Keep the thumb on the support side and not wrapped around, mimicking the thumbs forward grip on a pistol. This keeps the wrist locked and allows the support arm elbow to bend down holding the muzzle in place.
Getting behind the gun is not the same as sticking your butt out. Doing so can take you off balance and make it hard to move quickly.

Some instructors advocate gripping the handguard as far forward as possible with the thumb wrapped over the top. This “C grip” allows for solid control when driving the muzzle from target to target. However, when watching news footage from the wars in Iraq and Afghanistan, you’ll see many soldiers and Marines grasping the magazine well.

Years back, I broached this with a couple of recently returned Army Rangers and they told me they’d been trained in the C grip technique and liked it. But they also said when bullets are inbound and the muzzle is leading toward the threat (around the corner or over a wall), few want to place their hand near the muzzle so they pull it back and grasp the magazine well.

Sometimes the range and the street don’t meet.

Keep the head locked down on the stock. Not only does this give a consistent view through the optic, it also helps hold the gun firmly in place. With the head locked down and the shoulders forward, there’s no place for the gun to go so the recoil comes straight back, making follow-up shots fast. Recently, there has been a trend towards higher mounted optics to offer greater situational awareness, especially at close range. I’ve tried it and it feels odd to me, but I understand what is being accomplished. The choice is yours.

Spaulding prefers 20-round AR mags as they allow him to handle them like a pistol magazine . . .
…to include solidly inserting the mag in the mag well with the heel of his hand.

Once you’ve mounted the carbine as described, drop your strong side elbow. This performs a few important functions. First, it tightens the pectoral muscle, which helps solidify the carbine’s position. Second, it helps keep the elbow in and prevent injury. As someone who smacked his elbow on a door frame during a building search for a bank robber, I can’t express how important this is.

Incorporate tactics into your shooting. Tactics keep you from being seen and shot. Shoot around objects of various sizes and heights, move into and out of position, reload and run the gun in unorthodox positions. If you’re a law enforcement officer, practice pulling it out of whatever type of rack the gun is carried in while being transported.

Combative firearms training doesn’t vary greatly from weapon to weapon, it just needs to be relevant and prepare for the likely situations. Remember: Winning a gunfight usually comes down to adapting your practiced skills to the situation that’s unfolding before you.

    “I also think 20 rounds will handle all but the most extreme problems.”

    First mistake – assuming you know how a defensive encounter will play out. This is like the anti-gunners saying “limit magazines to 5 rounds, no one needs more than that.”

    I had one encounter, I’ve related before, where I went through all three of my 15 round mags, had three rounds left by the time the second bad guy went down and he still had several fully loaded magazines available. If he had not gone down when he did, after I needed to fire those last three rounds if they didn’t do the trick my wife and I would have died that day. This was after putting rounds in each of the two bad guys, one guy was down but still alive (but paralyzed due to a few round shot placement), the second guy even though wounded with several rounds in him was still up and engaging and I had advanced on him and finally when I was finally only several feet from him, after advancing over the 30 yards to get to my wife, he went down. Over half of the ammo I fired hit the bad guys – it was a moving fight, me advancing from cover to cover to save my wife from them, one of them firing at me, I still managed to put over half my shots in the bad guys when they exposed any part of their self from the cover they had.

    I had never thought until that day that I would ever use that much ammo in defensive encounter. After that I started carrying six 15 round magazines, I used a Glock 22 .40 cal that day, that was my EDC for 20’ish years. I’ve since retired that gun and due to a change in the needed carry method I’ve moved to a Sig P-365 X-Macro Tacops as my EDC now and carry six of the 17 round magazines for that.

    Lessons learned that day: First, and possibly last mistake you will ever make because this mistake can be fatal to you – never assume you know how a defensive encounter will play out, do not plan for how you think it will go but rather plan for how it can go as if every case will be the most extreme problem.
