How to Choose a Firearm Optic
Posted by SET Team on 21st Jul 2025
Introduction
A firearm optic can elevate your shooting precision, whether you’re using an AR-15 for home defense or a rifle for long-range hunting. With options like red dots, Low Power Variable Optics (LPVOs), and holographic sights, choosing the right optic can feel daunting. This guide explains how to choose a firearm optic based on type, function, and budget, helping you find the perfect fit for your needs. From affordable Holosun red dots to premium EOTech sights, SET Firearms offers expert advice and top brands. In this article, we’ll compare optic types, match them to shooting scenarios, and share maintenance tips.
Understanding Optic Types
Firearm optics come in several types, each suited to specific needs:
- Red Dots: Ideal for close-range shooting, red dots like the Holosun 507C offer fast target acquisition. They’re lightweight and versatile for AR-15s or handguns.
- Holographic Sights: Similar to red dots, holographic sights like the EOTech EXPS3 provide superior reticle clarity, even in bright conditions.
- LPVOs: Low Power Variable Optics like the EOTech Vudu offer adjustable magnification (1–6x), perfect for short- to mid-range shooting.
- Fixed Magnification Scopes: Scopes like the Trijicon ACOG are durable for long-range precision but less versatile.
- Iron Sights: Reliable backups, often paired with other optics for redundancy.
Each type has trade-offs, so consider your shooting style. Explore our optic selection or email sales@setfirearms.com for recommendations.
Matching Optics to Your Shooting Needs
Let’s explore which optic best fits your range and purpose:
- Close-Range (0–100 yards): Red dots or holographic sights excel for self-defense or tactical scenarios. A Holosun red dot suits a Glock for quick targeting.
- Mid-Range (100–300 yards): Fixed magnification scopes like the Trijicon ACOG provide precision for sniper or hunting rifles
- Long-Range (300+ yards):. LPVOs offer flexibility with adjustable magnification, ideal for hunting or competitive shooting.
- Reliability Needs: For rugged environments, choose durable optics like EOTech with backup iron sights.
Adding a magnifier to a red dot can bridge close- and mid-range needs. Browse our optics to find the right match.
Budget vs. Premium Optics
Optics range from budget-friendly to high-end:
- Budget ($100–$400): Brands like Holosun offer reliable red dots with features like solar power and shake-awake technology.
- Mid-Range ($400–$700): Options like the Trijicon MRO provide enhanced durability and clarity for versatile use.
- Premium ($700+): EOTech and Trijicon ACOG deliver superior performance and customer support for demanding conditions.
Keep in mind: budget optics may offer fewer reticle or brightness options. Customer service matters too—EOTech’s warranty is top-notch. From personal experience, Holosun also goes above and beyond with customer service!
Tips for Optic Maintenance
Proper care extends your optic’s lifespan:
- Cleaning: Use a microfiber cloth and lens cleaner to remove dust or smudges. Avoid abrasive materials.
- Storage: Store in a protective case to prevent scratches or impact damage or mounted on the firearm, stored in a safe location.
- Battery Checks: For red dots, replace batteries annually. Pick an easy to remember day like New year’s day, Tax Day, or 4th of July!
- Zeroing: Re-zero your optic after heavy use to maintain accuracy.
Regular maintenance ensures reliability. Contact sales@setfirearms.com for maintenance tips.

FAQ: Choosing a Firearm Optic
What’s the best optic for an AR-15?
Red dots like Holosun are great for close-range, while LPVOs suit versatile ranges. Choose based on your needs.
How do I zero a red dot sight?
Align the reticle with your target at a set distance (e.g., 50 yards) using windage and elevation adjustments. There will be a dial on the top (elevation) and typical the right (windage) on the optic. Moving these clockwise or counter clockwise will adjust those settings on the optic. Plan on shooting groupings of 3 to 5 rounds until happy with results.
Are LPVOs worth the cost?
LPVOs offer flexibility for short- to mid-range shooting, ideal for hunters or competitors. These optics always have a 1x setting allowing them to be used up close, but the real advantage is when the optic also has 8x or even 10x allowing you to push your rifle for future range targets.
What’s the difference between red dots and holographic sights?
Red dots use LED technology, while holographic sights use lasers for better reticle clarity.
