Rifles Resources & Guide
Whether you are configuring a modern sporting rifle (AR-15) for defensive home protection, setting up a bolt-action hunting rifle for the backcountry, or dialing in your precision optics, rifles offer unmatched stability and accuracy across distance.
An Intro to Rifles
This guide breaks down rifle mechanics, fundamental firing positions, optic mounting and zeroing, real-world ballistic considerations, highly practical FAQs, and specialized training courses offered by C2.
Rifle Fundamentals & Shooting How-To’s
Unlike handguns or rifles where precise single-point sight alignment dominates, shooting a shotgun effectively relies heavily on body mechanics, consistent gun fit, stance, and recoil management.
The 4 Fundamental Rules of Firearms Safety
Before handling any handgun, these four rules must be second nature:
-
Treat every firearm as if it is loaded. Never assume a firearm is clear.
-
Always keep the muzzle pointed in a safe direction. Never point a handgun at anything you do not intend to shoot.
-
Keep your finger off the trigger until your sights are on the target and you have made the decision to shoot.
-
Be sure of your target and what is beyond it. Know your target, backstop, and surroundings.

4 Elements of Precision Marksmanship
-
Steady Position: Whether prone, kneeling, sitting, or standing, your body must support the rifle’s weight using bone structure rather than raw muscle strength.
-
Cheek Weld & Sight Alignment: Establish a firm, repeatable contact between your cheekbone and the rifle stock (comb). This aligns your eye directly down the center of the scope or iron sights without strain.
-
Breathing Control: Shoot during your natural respiratory pause—the brief moment after you exhale before taking your next breath—to prevent vertical movement of the crosshairs.
-
Trigger Squeeze & Follow-Through: Apply smooth, steady rearward pressure to the trigger. Hold the trigger back through the shot until recoil settles, observing your target through the sight picture.
Optics, Zeroing, & Ballistic Considerations
Modern rifles rely heavily on optical sights—red dots, Low Power Variable Optics (LPVOs), and high-magnification precision scopes. Understanding how your optic integrates with your rifle is essential.
Choosing the Right Sight System
-
Red Dot Sights / Holographic Optics: Designed for fast target acquisition from 0 to 100 yards. Unlimited eye relief makes them ideal for defensive carbines and home defense.
-
Low Power Variable Optics (LPVOs - 1-6x or 1-8x): Offers true 1x unmagnified rapid acquisition at close range, with the ability to dial up to 6x or 8x for positive target identification out to 300–500 yards.
-
Precision Scopes (3-15x, 4-20x+): High-magnification optics paired with reticles measured in Milliradians (MIL) or Minutes of Angle (MOA) for precise long-range target work and hunting.
​
Understanding Sight Height vs. Bore Axis ("Height Over Bore")
Because a scope or red dot sits 1.5 to 2.5 inches above the center of the rifle barrel, your bullet starts its trajectory below your optic’s line of sight.
​
-
The Close-Range Offset: At extreme close distances (e.g., inside 7 yards in a home-defense scenario), your point of impact will land roughly 2 inches below where your crosshairs or red dot are pointing. You must physically aim higher on target to compensate for this offset.
Chris's Rifle Tip:
Mounting a scope is precision bench work—not a torque contest. Overtightening ring screws bends optic tubes, binds internal tracking turrets, and ruins accuracy. Use a proper torque wrench and level your reticle to the rifle frame before you ever head to the range.
Rifle FAQs
"What distance should I zero my defensive AR-15 or carbine?"
For most 5.56/.223 carbines, a 50-yard zero (or 36-yard zero) is ideal. A 50-yard zero puts your bullet trajectory within approximately 2.5 inches of your point of aim from point-blank range all the way out to 250 yards, allowing you to hold dead-center on a target without calculating complex bullet drop.
"Why does my rifle group shift after I shoot several consecutive rounds?"
As barrel steel heats up from continuous firing, internal stresses cause the metal to expand. On lightweight or thin-profile barrels, this thermal expansion causes the barrel to warp slightly, causing your shot grouping to drift or expand. Allowing your barrel to cool between strings preserves point of impact.
""What is the difference between 5.56 NATO and .223 Remington? Can I shoot both?
The Rule: You can safely fire .223 Remington out of a rifle chambered in 5.56 NATO or .223 Wylde. The Danger: You should not fire 5.56 NATO rounds in a rifle chambered strictly for .223 Remington. 5.56 NATO operates at higher internal pressures and has a longer chamber throat; firing it in a tight .223 Remington chamber can cause dangerous pressure spikes.
"How do I know what barrel twist rate I need for my ammo?"
Twist rate (e.g., 1:7", 1:8", 1:9") determines how fast the bullet spins to stabilize in flight: Heavy Bullets (75gr - 77gr): Require faster twist rates like 1:7" or 1:8". Medium Bullets (55gr - 62gr): Stabilize exceptionally well in 1:8" or 1:9" barrels. Light Bullets (40gr - 50gr): Work best in slower twist rates like 1:12".
"Is an AR-15 a practical choice for home defense or beginners?"
Yes. Despite common misconceptions, the AR-15 is one of the easiest rifle platforms for beginners to master. It has minimal recoil, lightweight ergonomic controls, adjustable stocks to fit any shooter's frame, and lightweight 5.56 rounds that fragment rapidly upon striking interior drywall, actually reducing dangerous over-penetration compared to many handgun or shotgun loads.
