Top 6 Best Red Dot For Derya Tm22 in 2026
The Derya TM22 is one of those .22 LR rifles that really benefits from a simple, fast red dot. I like it because the rifle already has the tactical feel of a centerfire carbine, but with cheap rimfire practice and very low recoil. That means I do not need a huge optic, heavy magnification, or an expensive long-range setup. I want a red dot that is light, easy to mount on the top rail, bright enough outdoors, and forgiving when I am shooting fast from casual positions.
For this guide, I picked six red dots that make sense on the TM22 for plinking, training, small-game-style practice, and rimfire range use. My top overall pick is the Sig Sauer Romeo5 because it gives me the best mix of price, size, battery life, and simple Picatinny mounting.
Quick Summary
For most Derya TM22 owners, I would start with a compact enclosed tube-style red dot. The TM22 does not kick hard, so extreme recoil resistance is less important than weight, clarity, battery life, and a mount that fits cleanly on the rifle’s Picatinny rail. The Sig Sauer Romeo5 is my favorite all-around option, the Vortex Crossfire is excellent for a clean lightweight setup, the HOLOSUN 403B is great for battery life, and the Bushnell TRS-25 is the budget-friendly pick I still trust for rimfire use.

Top 6 Best Red Dot For Derya Tm22 in 2026 in 2026
Sig Sauer Romeo5
The Sig Sauer Romeo5 is the red dot I would put on a Derya TM22 first. It is compact, simple, and well balanced on a lightweight rimfire rifle. I especially like it for range sessions where I want to move between paper, steel, and casual offhand drills without fighting the sight picture.
2 MOA red dot
Compact enclosed tube design
Multiple brightness settings
Motion-activated illumination
Common Picatinny-style mounting setup
Good fit for rimfire carbines and training rifles
Pros
Great all-around value
Small enough for the TM22
Crisp dot for the price
Easy controls
Battery-saving motion activation
Cons
Not as premium as Aimpoint
Small viewing window compared with open reflex sights
Basic look and feel
My personal experience with the Romeo5 has been very positive on lightweight carbines. On a TM22, I like that it does not make the rifle feel nose-heavy. The 2 MOA dot is fine enough for 25- to 75-yard rimfire work, but still fast enough for close steel. It is the optic I would recommend to someone who wants one red dot and does not want to overthink the purchase.
Online customer feedback is usually strong for the Romeo5 because shooters like the value, battery life, and reliability. The common complaints tend to be about the included mount height or users wanting a more premium glass feel, but for a .22 LR rifle, I think it hits the sweet spot.
Mounting is straightforward. The Romeo5 mounts directly to the Derya TM22’s top Picatinny rail using its included rail mount. No adapter or special mounting plate is normally required.

Vortex Crossfire
The Vortex Crossfire is another excellent match for the Derya TM22, especially if you want a clean, lightweight, no-nonsense red dot for training and plinking. I like it for shooters who value a simple optic with a good warranty reputation and a familiar control layout.
2 MOA red dot
Compact enclosed design
Lightweight body
Multiple brightness levels
Picatinny-compatible mounting
Good for rimfire rifles and carbines
Pros
Lightweight and compact
Clear sight picture
Good value
Simple to zero
Practical for range use
Cons
Not the widest field of view
Less feature-rich than some Holosun models
Basic illumination controls
I like the Crossfire on the TM22 because it keeps the rifle feeling fast. The Derya TM22 is not a heavy-recoiling rifle, so I care more about balance and usability than overbuilt bulk. The Crossfire gives me a clean dot, enough brightness for most outdoor use, and a simple setup that feels right on a rimfire tactical rifle.
Customer feedback often praises the Crossfire for value, ease of use, and reliable performance. Some users want more advanced features, but most rimfire shooters simply need a dot that holds zero and stays easy to see.
The Vortex Crossfire mounts directly to the Derya TM22’s Picatinny rail with its included rail-compatible mount. No adapter plate is needed for a standard top-rail setup.

HOLOSUN 403B
The HOLOSUN 403B is a great pick if battery life and low-maintenance ownership matter to you. On a Derya TM22, it gives me the compact tube-dot feel I like, but with Holosun’s practical feature set.
2 MOA red dot
Enclosed micro red dot design
Long battery life
Multiple brightness settings
Lightweight housing
Picatinny rail mounting compatibility
Pros
Excellent battery life
Compact size
Good dot clarity
Lightweight on the TM22
Strong value for frequent shooters
Cons
Buttons may feel small with gloves
Not as open as a reflex window
More expensive than basic budget dots
My personal experience with Holosun micro dots has been that they are easy to live with. On the TM22, the 403B feels like a practical training optic. I can leave it set up for range use, pick up the rifle, and get a fast sight picture without adding unnecessary weight.
Online customer feedback is generally positive around battery life, durability, and value. Some shooters compare it directly to more expensive duty optics, while others simply appreciate that it works well without costing premium-optic money.
The HOLOSUN 403B mounts directly to the Derya TM22’s Picatinny top rail with a compatible rail mount. No adapter or separate mounting plate is normally needed.

Bushnell TRS-25
The Bushnell TRS-25 is the budget red dot I think of first for a rimfire rifle. It is not fancy, but on a Derya TM22 it makes a lot of sense for casual plinking, first-time red dot users, and anyone building a fun range rifle without spending too much.
3 MOA red dot
Compact tube-style optic
Simple brightness dial
Picatinny rail compatible
Lightweight build
Budget-friendly design
Pros
Very affordable
Simple controls
Good for casual rimfire shooting
Compact size
Easy to mount
Cons
Not as refined as newer red dots
Battery life is not class-leading
Dot may look less crisp to some eyes
I have always viewed the TRS-25 as a practical “get shooting now” optic. On the TM22, that is not a bad thing. The rifle is fun, inexpensive to shoot, and easy to run quickly. The TRS-25 keeps the setup affordable while still giving me a much faster sight picture than basic iron sights.
Customer feedback usually focuses on value. Many shooters like it for .22 rifles, range guns, and inexpensive builds. The most common criticisms are that it feels older compared with newer optics and lacks premium features.
The Bushnell TRS-25 mounts directly to the Derya TM22’s Picatinny rail. It does not require an adapter plate for standard top-rail mounting.

Aimpoint PRO
The Aimpoint PRO is more optic than most Derya TM22 owners strictly need, but it is the one I would choose if durability is the top priority. It gives the TM22 a serious carbine feel and makes sense for shooters who want a premium red dot that can also move to other rifles later.
2 MOA red dot
Full-size enclosed tube design
Rugged duty-style construction
Long battery life
Included mount system
Designed for hard-use carbines
Pros
Excellent durability
Proven design
Clear, usable dot
Strong mount setup
Great if shared across rifles
Cons
Heavier than micro red dots
More expensive
Larger than necessary for most rimfire use
My personal take is that the Aimpoint PRO feels almost overbuilt on the TM22, but in a good way if you like serious gear. The weight is more noticeable than the Romeo5 or Crossfire, yet the sight picture is confident and the controls are simple. I would pick it for a TM22 that doubles as a training analog for a centerfire rifle.
Online customer feedback is usually excellent, especially from shooters who value reliability and ruggedness. The main drawback people mention is size and cost, which is fair on a .22 LR platform.
The Aimpoint PRO mounts directly to the Derya TM22’s Picatinny rail using its included rail mount. No adapter plate is normally required, though its larger size may make placement more important for balance.

HOLOSUN 510C
The HOLOSUN 510C is my pick for shooters who want a big, fast window on the Derya TM22. It is larger than the micro tube options, but the open sight picture makes fast target transitions feel very natural.
Open reflex-style red dot
Large viewing window
Multi-reticle style design
Solar-assist style feature set
Picatinny rail compatible
Good for fast close-range shooting
Pros
Large, fast sight window
Easy target transitions
Feature-rich design
Good for steel and range drills
Comfortable heads-up shooting
Cons
Bigger than a micro dot
Open emitter is more exposed
May be more optic than casual plinkers need
I like the 510C when I am shooting fast. On the TM22, it makes close-range rimfire drills feel almost effortless because the window is forgiving and easy to pick up. It is not my first choice for the lightest possible setup, but it is one of my favorites for fun range work.
Customer feedback is usually strong for the big window, reticle options, and overall value. Some shooters prefer enclosed optics for weather protection, but on a range-focused TM22, I think the 510C is a very enjoyable choice.
The HOLOSUN 510C mounts directly to the Derya TM22’s Picatinny top rail with its integrated rail mounting system. No adapter or mounting plate is normally needed.

How to Choose the Right Red Dot Sight
For the Derya TM22, I look at five things first: weight, mount type, dot size, battery life, and intended use.
A compact tube red dot is usually the safest choice. The TM22 already has a tactical rifle shape, and a small enclosed optic keeps the rifle balanced. I prefer a 2 MOA dot for most rimfire work because it is precise enough for small targets at 50 yards, but still fast up close. A 3 MOA dot also works well if most of your shooting is casual plinking.
Mounting is simple because the best setup is usually a direct Picatinny rail mount. I avoid pistol-style micro dots unless I have a specific adapter, because a rifle-style red dot is easier to mount and easier to position correctly on the TM22.
For budget builds, the Bushnell TRS-25 is hard to ignore. For the best overall setup, I would choose the Sig Sauer Romeo5. For speed, the HOLOSUN 510C gives me the most open and forgiving view. For premium durability, the Aimpoint PRO is the strongest option, though it is heavier than I personally need on a .22 LR rifle.
