I spend a lot of time in my truck. It’s my primary everyday driver.
The reason I chose the truck that I did is that it can do nearly anything I need it to do.
Ensuring that my truck is as capable as possible also involves being equipped with the necessary firepower for a variety of situations. That firepower comes in the form of a truck gun.
The situations include self-defense, the defense of others, and general sporting opportunities. If I want to go to the range on the spur of the moment, I can since I have everything in my truck already.
You can also find them used on GUNS.COM for around $636 (as of the time of this writing).
Some of the specs that stand out to me the most are the 1:7 twist rate in a Ballistic Advantage barrel, mid-length gas system, and M16 BCG.

Benefits of the 1:7 Twist Rate
If you’re looking for a MIL-SPEC clone, the 1:7 twist rate is it. The U.S. military adopted this setup in the 1980s for its M16A2 service rifle running a 62-grain M855 round.
Also found in the M4, M16A4, Mk12 SPR, and HK416, the 1:7 barrel twist rate can stabilize up to a 90-grain bullet, and handles the popular 77-grain bullets across a wide spectrum of velocities.
Benefits of the Mid-Length Gas System
Mid-length gas systems are known for providing a better shooting experience compared to a carbine-length gas system.
The mid-length gas system is also more reliable across a wide range of ammunition and running suppressed or not.
The mid-length gas system helps out a lot by decreasing the felt recoil. Many cheaper AR-15s come with a carbine-length gas system.
The Mid-Length also gives you a little better performance because you get a little bit less gas to the parts and get a little longer durability on the parts as well, especially for cheaper-made Parts which I’m sure are not the same quality as BCM or Daniel Defense.
The firing pin is fully shrouded so that the hammer is cocked by the carrier and not the firing pin itself.
The M16 bolt carrier is heavier and therefore increases “unlocking delay" (or the amount of time that the empty case remains in the chamber after the primer is struck by the firing pin) which aids in extraction.
The heavier carrier also reduces the felt recoil impulse which in turn provides a smoother operation and reduces wear and tear on the AR15.

You’re probably wondering what the hell I’m not running some type of red dot sight. While I do have a few red dot sights and holographic sights such as the EoTech 512, I wanted to keep this build as simple, durable, and cost-effective as possible.
I qualified in the Marine Corps on iron sights out to 500 yards and am very comfortable and confident in using them. I can confidently take shots out to 100 yards which is about the farthest I’m going to be engaging targets realistically.
The Midwest Industries Combat iron sights for the AR15 are a modern take on the old-school M16 iron sights. They are easy to install, use, durable, and affordable.
Sling | Magpul MS1 2-Point Rifle Sling
In keeping with an affordable build without compromising on the quality I chose the Magpul MS1 rifle sling.
The MS1 Rifle Sling is the most versatile addition to the Magpul line of rifle slings. The MS1 slider system provides rapid adjustments to either lengthen or shorten the sling with no slipping once it’s set, with no excessive tails, loops, or other potential snag hazards.
Reducing snag hazards are something to keep in mind with a truck gun. You don’t want it getting wrapped around or hung up on something when you need it fast.
Although 55 grain is widely available and the most common load, I prefer to go with a heavier projectile for the purposes of the truck gun.
Although I do prefer a 75 to 77-grain projectile they can be more difficult to find. Why the heavier weight? They tend to buck the wind a little better, have a little more ass behind the projectile, and have better terminal ballistics.
