In this guide I’m going to show you the best ACOG clone.

In fact:

These are the same clones that many optic experts and competitive shooters use.

The best part?

I’ve sorted the clones by use. So whether you’re on a budget or need a solid trijicon acog clone, you’ll find it here.

Let’s get started!

The 3 Best ACOG Clone

If you’re pressed on time, here’s a quick list of the best ACOG clone:

  1. Lucid 4x: Best 4×32 ACOG Clone
  2. NcStar Mark III 3-9X42: Most Premium Trijicon Clone
  3. Monstrum P332 Raven 3X: Best for the Budget

1. Lucid 4x: Best 4×32 ACOG Clone

The Lucid P7 4x Primastic Weapons Optic is the best 4×32 ACOG clone.

Trijicon is well-known for its line of nearly indestructible, low magnification optics that are battle-tested. As impressive as it is, not everyone can afford to drop $1000-2000 for an ACOG.

In fact, this is how I discovered the Lucid P7 4x. I spent weeks looking for a rugged short to a mid-range optic that holds zero and serves well in all my shooting applications. Trust me when I tell you this: the Lucid 4x Prismatics Weapon Optic was exactly what I was looking for.

Glass Clarity & Reticle

The Lucid P7 4x sports an incredibly clear, premium glass, built just like an ACOG.

Sometimes, I notice a slight distortion around the edges when I’m shaking my head around. But truth be told, unless you’re looking for it, it’s hardly noticeable. Plus, the Lucid P7’s glass quality is undoubtedly better than other competitors in the $300-$500 range.

The P7 reticle offers fast targeting with a highly useful ballistic MOA measuring tape. It has a dot surrounded by an 8 MOA circle, with bullet drop lines in 8 MOA increments underneath it. The P7 comes with red and blue illumination designed to be powered by a single AA battery.

A single AA provides up to 2500 hours of active target use, which is fantastic. I’ve experienced no problems when I tested the Lucid P7 with Duracell, Energizer, and other drugstore brand batteries.

However, one downside, Lucid doesn’t provide a warranty for leakage or corrosion damage caused by the batteries. So remember to buy less leak-prone lithium cells if you know you’ll end up leaving the battery in the scope for long periods.

The Lucid P7 features a Strelock Ballistics App. I had downloaded the said app on my iPhone and decided to test it out with my Ruger AR-556 that I use for hunting deer and other varmints. I plugged in the calculations for the bullets, and let me tell you this: it was so easy to zero that I dropped back and verified hold-overs at a few extended distances.

In fact: I was so impressed with how the Strelok calculations matched that I used it hunting until sunset.

Speaking of dusk, the Lucid P7 offers a good range of manual illumination settings, but the auto-brightness sensor is a feature I’d like to highlight. You won’t have to take your hand off the weapon to change the reticle’s brightness when going from a bright to a darker environment. The sensor was able to adapt to the changes in lighting very quickly.

Eye Relief & Eye Box

The Lucid P7 4x comes with a forgiving 3-3.5 inches of eye relief.

This stood out to me as most Trijicon ACOGs have somewhat less than that.

On the flip side, the Lucid P7’s field of view is marked 25ft at 100 yards. This is slightly more limited than the field of view of a Trijicon 4×32 ACOG but is still pretty decent for its price tag.

Durability and Weight

The Lucid P7 4x is exceptionally rugged and durable.

Thanks to its aircraft-grade, one-piece aluminum tube construction with chemical rubber housing, this scope can withstand heavy use and harsh recoil.

Not only that, but the Lucid P7 is entirely waterproof, shockproof, and fog proof.

The biggest disadvantage to the Lucid P7 is its weight, which comes in a whopping 19 ounces with the battery. However, if this is the cost for increased durability and high performance, I’ll take it any day.

Elevation & Windage

The Lucid P7’s elevation and windage turrets are smooth with precise clicks that can be heard and felt.

The adjustments operate in 1/2 MOA clicks and have proven to be highly accurate and track true. The exposed, resettable turret caps were convenient when I had gloves on or when my fingers were wet in cold weather.

I mounted the Lucid 4x on my Bergara BXR, and it took me 20 rounds to zero the scope. After shooting 500 rounds, it still held zero perfectly.

Magnification & Parallax

The Lucid P7 comes with a fixed four power magnification and a 30mm objective lens that comes threaded for a killflash filter.

The scope comes with a side parallax adjustment. Combined with the ocular diopter adjustment, it provides any shooter a clear image over the entire magnification range.

Mounting & Rings

The Lucid 4x comes with a sturdy Picatinny rail mount built-in for secure and reliable mounting. It works perfectly for AR-15 platforms.

Also, the mounting was effortless regardless of the firearm. A word of advice: be sure to really torque down the screws because they can get loose.

Is the Lucid P7 4x Combat Optics worth it?

If you’re looking for an optic that’s as strong and reliable as a 4×32 ACOG but without the hefty price tag, get the Lucid P7 4x Prismatic Weapons Optic.

Why? It’s got…

  • 4x magnification
  • Crisp glass quality
  • Forgiving eye relief
  • Illuminated P7 reticle
  • Auto-brightness sensor
  • Auto shut off after 2 hours
  • 2,500 battery life on a single AA
  • Fogproof, waterproof, and rugged

To top it all off, the Lucid P7 4x scope is protected by Lucid’s Limited Lifetime Warranty. If the product arrives with a defect due to materials or workmanship, the company will replace or repair it.

For under $400, the Lucid P7 4x Prismatic Weapons Optic offers a remarkable amount of features housed in a body that’s built like a tank. Trust me: you won’t worry over spending thousands on a Trijicon ACOG ever again.

  • Auto brightness sensor - so the operator does not have to take a hand off the weapon to manipulate the reticle brightness when going from a bright environment to a darker one
  • Available kill flash filter
  • Mounting - a robust Picatinny rail mount is built in for secure and rock solid mounting to most weapons platforms

2. NcStar Mark III 3-9X42: Most Premium Trijicon Clone

The NcStar Mark III 3-9X42 claims to be a trijicon acog clone, but it is an absolutely amazing scope in it’s own category.

The price tag is unbeatable, but this sight will blow you away with the insane quality and features that are packed into this budget scope.

Here’s why the NcStar Mark III 3-9X42 is one of the best trijicon clone’s I have ever used…

Glass Clarity & Reticle

The clarity on the NcStar Mark III 3-9X42 has been far better than anything else I have used in this price category.

Easily outdoes other acogs I have used that are two times the price.

The clarity on this sight seems to max out around 250 yards which is perfect for my shooting tendencies.

Not only does this sight come with a 3-9X acog, but it also has a close range red dot window up top.

This is the first time I have used a sight with this feature and I am really enjoying it so far.

Swapping from long range to short has never been so simple.

The red dot up top is a great complement to an already fantastic sight.

I am using this sight on my .223 AR and it has been a great addition to one of my favorite rifles.

Eye Relief & Eye Box

The eye relief is a little bit variable based on the magnification; however, with the quick release mount that comes stock this has not been a huge issue for me.

It is not often that I am switching my magnification more than once out at the range so I have rarely noticed this issue.

The eye relief has been great for the recoil on my .223 AR and I am assuming it could easily handle .308 recoil and not get too close to my eye.

The eye box is more than large enough for my viewing needs and I have had no issues.

With beautiful great clarity and an amazing field of view, the NcStar Mark III 3-9X42 has not left my AR since I purchased it.


One prerequisite I would recommend for the NcStar Mark III 3-9X42 would be to tighten and loctite some of the mounting screws.

I read a few reviews prior to purchasing the sight and this was a common complaint so I did it the second I opened the box.

I have had absolutely no issues with any of the hardware which makes me think I probably didn’t even need to do it.

Overall, the NcStar Mark III 3-9X42 is a very strong piece of hardware and it has taken a beating alongside my AR.

The quality you get far outweighs the price tag of the sight.

Elevation & Windage Knobs

The elevation and windage knobs are beyond premium for what you pay for this sight.

At this price range I would expect some crappy, wobbly plastic turrets with terrible motion.

However, you get high quality turrets with great movement. The click is very solid and they snap into place perfectly.

Finding a zero on the NcStar Mark III 3-9X42 was unbelievably easy and I have only had to re zero once or twice in the past few months.

Given, I use my AR multiple times a week.

The zero has held fantastically well, but after a few months I find it has drifted ever so slightly so I give it a click or two and we’re back to perfect.

Parallax & Magnification

The magnification on this sight is 3X to 9X which has been perfect for my usage.

(If you need a 1-6x range, check out my best LPVO optic guide).

In addition, it comes with the red dot on top that is at 1X. The combination of both of these is a pleasure to use at the range.

As you increase the magnification I have noticed a slight parallax that comes with the eye relief issue I mentioned earlier.

This was not a dealbreaker for me because the sight is still an amazing purchase in my mind.

Mounting & Rings

The NcStar Mark III 3-9X42 comes with an unbelievable quick detach mount.

I am always slightly sceptical about quick detach mounts when they come stock because I can be very picky about my mounting.

This quick detach mount is definitely one of the better ones that I have used and I don’t plan on taking it off.

I would definitely recommend keeping the quick detach mount on the sight, it has been a dream to use.

Is the NcStar Mark III 3-9X42 worth it?

The NcStar Mark III 3-9X42 touts itself as a Trijicon clone. The word clone tends to give a negative connotation; however, this sight does not deserve the clone name.

Here’s why:

  • Dual reticle
  • Unbeatable price
  • Magnification versatility

In short: The NcStar Mark III 3-9X42 is high quality and comes in at a price tag that makes me wonder why I haven’t bought another one yet. I can promise this sight will be an amazing addition to any AR build that won’t break the bank.

NcStar Mark III Tactical P4 Sniper 3-9X42/Scope Adaptor Mount/Red Dot Combo Package (STP3942G/D)
  • Mark III tactical scope with backup red dot sight
  • Fully multicoated lenses offer brightness and clarity
  • Red/green illuminated P4 sniper reticle with multiple brightness settings

3. Monstrum P332 Raven 3X: Best for the Budget

The Monstrum P332 Raven 3x is the best sight for the budget.

In fact:

After comparing every prism scope in the under $300 category, I still keep this sight on my firearm today.

Here’s why…

Glass Clarity & Reticle

The Raven might be a budget sight, but it comes with a competitive high quality lens.

The fully multi-coated quartz lens gives a bright, high quality picture without any of the typical imperfections you see in a budget scope. Plus, the optic lens coating also reduces glare so you won’t give away your positioning.

It’s better glass at half the price.

The circle dot reticle is crisp albeit simple. It’s glass etched with a 3 MOA dot and 60 MOA circle.

It’s a very basic reticle, but for short- and mid-range shooting it’s great for fast target acquisition.

The reticle can also be illuminated either red or green with 5 brightness settings per color.

The illumination does decently well in the daytime, but I’d say that the unilluminated black reticle shows up the best in daytime lighting. The illuminations settings work best for dusk or low-light situations.

Eye Relief & Eye Box

The 3.0-3.5 inches of eye relief allows for scoping with one eye or two.

The eye box is good as well, especially considering the price, and not too difficult to get your cheek in the right position.

That, paired with the solid eye relief makes it a great optic to target with both eyes open. This makes it great for fast target acquisition in home defense or for people who have trouble sighting a traditional scope.


The P332 Raven might be affordable, but it’s not cheap. This scope is built to withstand serious abuse.

The scope body is single piece machined from 6061 aluminum meaning fewer moving parts and less points of failure so the scope can withstand serious recoil.

It’s stood up to all of my abuse, deliberate and not.

It’s water and shockproof. The nitrogen sealed body also prevents the scope from fogging so you’ll always have a clear shot, rain or shine.

Added to this, the turret caps are rubber o-ring sealed which prevents dust and corrosion from damaging the scope.

It’s budget friendly, but built to last.

Despite being compact, the Raven is a beefy optic. At 15 ounces, it’s nearly an added pound to my weapon setup.

That being said, it’s the lightest option in the Monstrum line to date, and a more lightweight option will cost you at least three times as much.

Elevation & Windage Knobs

The windage and elevation adjustments are somewhat crude and require a screwdriver or coin to adjust.

The clicks on the adjustments are weak, but they don’t change once they’re set.

Zeroing was quick and easy. I’ve put more than 200 rounds through this scope and it’s held fast.

Parallax & Magnification

The P332 Raven is a fixed 3x magnification. It works well for close range, 200+ yard shooting.

The fixed magnification means less fiddling with settings and more shooting. While it is fixed at 3x, the diopter can be manually adjusted to focus your image whether at 25 or 300 yards.

Overall, I’ve found that this optic performs its best at mid-range, 15-200 yards primarily.

(If you need more range than that, check out my long range scope guide).

Mounting & Rings

No need to shop around for added rings or risers since the Raven comes built to mount with an integrated mount system.

It mounts on any Picatinny rail platform with no additional equipment. The scope mount uses hex nuts with flat-head screwdriver cutouts.

(Looking to get into competition? Check out my top scope picks for 3-gun shooting).

Is the P332 Raven 3X worth it?

A crisp dot, clean picture, and durable optic body are some of the premium features that make this sight stand out at a fraction of the price.

The fixed 3x magnification and simple reticle design are why I recommend it for home defense and quick, mid-range target shooting.

Here’s what sets it apart from the competition:

  • Circle dot reticle
  • One year warranty
  • Fully multi-coated quartz lens
  • 6061 Aircraft Grade Aluminum body

Once you get your hands on the Monstrum P332 Raven 3x, you’ll wonder how you didn’t pay twice as much.

Monstrum P332 Raven 3X Prism Scope
  • With a glass prism optic system the Monstrum P332 Raven gives you true 3x magnification with crisper optics in a smaller package than traditional refracting lens rifle scopes
  • The etched glass reticle illuminates in both red and green for a clean sight picture regardless of lighting or environment, visible with or without battery powered illumination source
  • The single piece machined aluminum body is built with fewer moving parts and less points of failure to hold zero against the fiercest of recoil
