How to Choose the Right AR-15 Rifle Stock
When it comes to customizing your AR-15, one of the most impactful upgrades is the rifle stock. The right stock not only enhances shooting comfort and accuracy but also plays a major role in weapon control and overall performance. With a wide range of styles and features available, choosing the perfect AR-15 stock can be overwhelming—especially for first-time builders or new gun owners.
In this guide, we’ll break down the key factors to consider when selecting an AR-15 stock that suits your shooting style, body type, and intended use.
1. Fixed vs. Adjustable Stocks
The first decision is whether you want a fixed or adjustable (collapsible) stock.
-
Fixed Stock: Offers greater stability and durability. Ideal for precision shooting and long-range accuracy. However, it lacks the versatility of length adjustment.
-
Adjustable (Collapsible) Stock: Can be extended or collapsed to fit shooters of different sizes or to accommodate body armor. Perfect for tactical or defensive use.
Best For:
-
Fixed Stock – Bench shooting, hunting, precision builds
-
Adjustable Stock – Home defense, tactical applications, all-purpose use
2. Mil-Spec vs. Commercial Buffer Tubes
Make sure your new stock is compatible with your buffer tube.
-
Mil-Spec: Standard military dimensions. Most aftermarket stocks are made for mil-spec tubes.
-
Commercial: Slightly larger diameter and different shape. Not interchangeable with mil-spec stocks.
Pro Tip: Always verify the diameter of your buffer tube before buying a stock to avoid fitment issues.
3. Weight & Material Considerations
A heavy stock can add stability but may reduce maneuverability—especially in a home-defense or close-quarters environment.
-
Polymer Stocks: Lightweight and corrosion-resistant. Most popular choice.
-
Aluminum or Hybrid Stocks: Offer additional strength but can be heavier and pricier.
Choose a stock that balances durability, weight, and comfort for your intended use.
4. Ergonomics & Comfort
Look for features that improve shooter comfort:
-
Rubber Butt Pads: Help absorb recoil.
-
Adjustable Cheek Rests: Provide better sight alignment with optics.
-
Textured Grip Surfaces: Improve handling in wet or gloved conditions.
If you’re spending extended time at the range, these features can make a noticeable difference.
5. Intended Use & Shooting Style
Your application should influence your stock choice:
| Use Case | Suggested Stock Type |
|---|---|
| Home Defense | Lightweight collapsible stock |
| Precision Shooting | Fixed stock with cheek riser |
| Hunting | Adjustable or minimalist stock |
| Tactical/3-Gun | Collapsible with quick adjust |
