The .300 BLK is becoming popular among hunters and competitive shooters alike because it gives them the opportunity to use the same rifle for different purposes just by changing the round and adjusting the gas system. This cartridge works really well in short barrel rifles and has good ballistics for shooting targets at typical ranges when using a suppressor.
You’ll do fine with a red dot if you’re using your rifle for CQC or self-defense,. But for hunting, a scope with a variable magnification range of 2-7x or 3-9x would be a good choice. A reticle with a simple crosshair or a duplex reticle is also a good option.
The ultimate choice will depend on your intended use and preferences, but here are some of the best .300 Blackout scopes that you should look into.

.300 Blackout Scope Buying Guide
1. Intended Application
Your purpose determines the quality of and the budget for your scope. For example, are you buying your rifle accessory for target shooting, lawful combat activities, hunting, and other recreational shots? With this in mind, you can make a worthy investment and maximize the effectiveness of your device.
2. .300 Blackout range and magnification
Figure out your most comfortable shooting range and if you shoot across different zones, opt for an optic with adjustable magnification.
- Close range – The .300 blackout is optimized for this range as it has the highest power. Ideal magnification for a distance of 20 to 150 yards is 1-4x.
- Medium range – This is the perfect position if you’re clearing off varmints from your area. At 150 to 300 yards, you’ll use a magnification power of about 5 – 9x.
- Long-range – Here, you’ll likely take down a few games because of the drop in penetrative power, but if you’re with the right scope; it’s worth the try. So, at 300 yards and above, you’ll be using 9x magnification or more.
3. Quality of light filtration
You need a scope with a multi-coated lens that can filter and transmit light appropriately.
4. Quality of lens
Look for a high-quality glass that’s immune to finger stains, dirt, and scratches.
5. Types of Reticles
- BDC Reticles – These are perfect for target and long-range shooting at 250 yards and above.
- MOAR – Works best when aiming at small targets.
- Duplex Reticle – This is the trendiest and most natural to use. It’s for mid-range shootings, making it an excellent choice for the 300 round.
- ACSS – This is for drop bullet drop compensation, leads, and range estimation.
- Mil-Dot Reticles – You’ll have to use mil-dot for MRAD measurements during tactical shootings.
6. Strength & Durability
Your scope should have a robust exterior that’s proof to impact, moisture, fog, and dirt. A quality scope can withstand tough circumstances and harsh weather elements without losing its functionality.
7. Scope Weight
Find the best .300 Blackout scope that’s compact and lightweight enough to keep your rifle balanced while still offering an amazing performance.
8. Eye Relief
The term eye relief describes the sufficient distance between your eyes and the view window. Most scopes allow your eye to be several inches away from the lens while others only need half an inch.
However, more extended eye relief means a more comfortable shooting and fewer incidences of recoil striking your face. We recommend scopes with at least 6 inches.
9. Type of Platform
Generally, there are three platforms for the .300 blackouts; these are pistols, AR rifles, and short barrel rifles
- .300 Blackout Pistols – While there are lots of reasons for buying the AR-15 handguns, top of the list is that they serve as a reliable substitute for any short barreled rifle (SBR), making the .300 AAC their most excellent cartridge.
- .300 Blackout Rifles and Carbines – Depending on what you’re hunting for, you’ll either choose a simple or complex scope. Of course, you won’t use the same optic for a patrol carbine as you would for hog hunting.
- Short Barrel Rifles – When you’re not shooting at a great distance, the usual cartridge is a heavy subsonic, and there’s no need to increase your firearm’s weight with an enormous powerful scope.
10. Type of Optic
When you’re hunting with hypersonic ammunition, using an optic will help increase your target accuracy. You’ll likely have issues when pairing a .300 blackout rifle with scopes with higher magnification or exposed turrets. For best results, consider using the best 300 Blackout scope with 6x to 8x magnifications.
However, subsonic rounds will work well with low magnification scopes as they’re more useful within 100 yards. Optics like red dot sights, holographic sights, and other small power scopes have faster target acquisition and allow you to make transitions between targets easily.
Always check the reticle markings on the scope to ensure it’ll match your .300 blackout caliber.
Your sight should match the quality of your rifle. If you use a high-end optic scope with a cheap gun, you’re probably going to downplay most of its specs. The price ranges between $150 to $200. Many variables determine their costs e.g. those with fixed magnification are relatively cheaper.
Ideally, we don’t think you’ll find the best optics for .300 blackout under $100 because they might lack many crucial features. Make sure you invest in a scope with a good build-quality that can withstand the power from the AR-15 rifles and .300 blackouts.
What’s So Special About the .300 Blackout?
- Short to moderate range and can perform with supersonic and subsonic rounds
- Can save barrel life due to its lower powder charge
- Perfect for use with a suppressor
The .300 Blackout is a short to moderate range round. Ideally, it was designed to outperform the 5.56 magazine and perfect the flaws found in the AR-15’s rifle. The 5.56 can only perform at its peak with the 20-inch barrel but will lose range and momentum if you shorten the gun’s length.
Compared to the 6.8 cartridge (SPC) that’s more powerful than the 5.56, the .300 blackout has a unique capability as it drops 2 inches lower than the 6.8 SPC. Also, the 6.8 SPC has a higher velocity and muzzle energy rating than the .300 blackout round.
But the 6.8 SPC has a more challenging conversion because it’s design was based on the old .30 Remington cartridge which requires a different bolt and less standard magazine capacity. So, the .300 blackout is specifically for ease of conversion. It allows you to use the standard bolt and a full capacity magazine by only changing the barrel and gas system.
However, the .300 blackout reaches its highest performance with a 9-inch barrel. It can perform outstandingly with both supersonic and subsonic rounds. Besides, you can easily swap between subsonic and supersonic mags to enhance their potential. It’s mostly found in single shotguns, AR-15, and bolt action rifles.
Cleaning & Maintenance Tips
- Keep cleaning kits handy – Since the weather might change unexpectedly, keep your lens pen and cleaning cloth in your backpack to wipe off raindrops or mud splatter.
- Wipe the lens before and after use – After you have invested in a fantastic scope, you wouldn’t want to lose the lens to scratches. Make sure you remove every speck of dust that could degrade its clarity.
- Avoid spraying cleaner directly on the lens – Only spray the cleaning liquid on the cloth since too much moisture could harm the lens’ coating.
- Use a Lenspen – Most hunters and photographers prefer lens pens because they can clean without moisture. Fortunately, they’re quite affordable and easy to use.
- Get a microfiber cloth – Instead of using paper towels, toilet tissues, and Kleenex to wipe the lens; we recommend a microfiber cloth since it won’t scratch the surface nor leave behind cotton fibers.
- Cover the lens – Always keep the caps on whenever you’re not shooting and when cleaning your rifle. This will protect it from dust and prevent the liquid from harming the lens’s waterproof seal or coating.
- Clean the turrets and battery compartment – If you’re hunting in a dusty or windy environment, unscrew the turrets and wipe them thoroughly to prevent rust.
1. Can I shoot .223 in my .300 blackouts?
Ans. A .300 BLK round will chamber in a 223 rifle but will never fire accurately. This is because the 22-caliber bore isn’t big enough to handle the. 30 caliber of the 300 blackouts.
2. What is the benefit of .300 blackouts?
Ans. The .300 blackouts were designed to enhance the firing and penetrative power of the AR platforms. Besides, the .300 BLK has a wider range of projectiles and can quickly cycle both subsonic and super ammunition.
3. Which is better – 5.56 or .300 blackout?
Ans. For target shooting and training, the .300 BLK will get expensive after firing many shots and we’ll recommend 5.56 for that reason. You’ll need the lethality of the 300 AAC if you’re targeting animals like deer or hogs. The extra weight of the .300 blackouts gives more penetration, but for small games, choose the 5.56. Though the .300 BLK can’t replace the 5.56 blackout, it does outshine in most areas.
4. What is the best barrel length for .300 blackouts?
Ans. Although 8″ to 16″ barrel lengths work well with the .300 blackout, a shorter 8″ to 10″ barrel provides better maneuverability and ease of use in close quarters or when hunting in dense terrain but you’ll have slightly reduced velocity and accuracy at longer ranges.
5. Is .300 blackout or 223 quieter?
Ans. The .300 Blackout is superbly silent when compared to the 223 round.
6. What magnification makes the best scope for 300 blackout hunting?
Ans. Most hunting activities take place at 200 yards or higher ranges. To see well at these ranges, you will need 3X or 4X magnification. You can use scopes with more variables to hunt at longer ranges.
