Vortex Venom - Lightest Weight
Why we pick this one - The Vortex Venom is a 3 MOA rapid target acquisition reflex sight made with aluminum housing that is durable for range use, and it mounts directly on to the top rail by tightening the screw.
Wide field of view - Get on target fast by looking through a big window for tracking the reticle better and not get lost.
Clean Reticle - Red Dot works for shooters with astigmatism under most lighting situations
Top-Loading Battery Access - Swap the battery right from the top similar to the Burris FastFire 3 without removing the whole sight or having to re-zero the sight
What people are saying about it - Overall, the Vortex Venom is a fairly large FOV sight without breaking the bank for just under $250. Target acquisition is fast along with the bright fiber optic front sight that makes shooting the Ruger 22 an amazing experience.

Pros
Cons
Holosun 507C X2 - Most Versatile
Why People Love This Sight - The Holosun 507C is by far the best Trijicon RMR alternative for the performance and price. Use it on the Ruger MARK IV and other firearm types when you get finally tired of shooting 22LR.
Same RMR Mounting Footprint - It shares the same mounting footprint as the RMR, so no need to buy a special mounts
Superior Durability - Forged 7075 T6 aluminum housing unit protects the internal component to retain zero from sharp recoil impulses and rough handling.
Side Loading Battery - Access CR1632 battery from the side tray instead of the bottom. This eliminates the need to remove the sight for battery swap and re-zeroing
Near Infinite Battery life - The Shake Awake technology saves tons of battery life by deactivating the optic when at rest, then turns it back on upon movement. 2X more battery life than the Trijicon RMR up to 50,000 hours
Solar Power BackUp - Solar fail-safe power kicks in immediately when the battery dies, so the optic will always remain on.
Multi-Reticle System - Cycle through the following reticle options for various applications:
- 2 MOA Center dot
- 32 MOA circle
- 32 MOA circle + 2 MOA Dot
*Change by pressing the minus button for 3 seconds.
The 32 MOA circle helps significantly for picking up the sight faster because it's big and easier to see.
Pros
- As durable as Trijicon RMR and much more affordable
- Uses RMR footprint
- Motion activated reticle to save battery even more
- Use it on other guns when tired of shooting 22LR
Cons
- Need special tool to pull the battery tray out and adjust MOA turrets
- Indoor light source doesn't activate solar power

Ruger MARK IV Red Dot FAQ
What's the Effective Range of 22LR
The effective range of a 22 LR round can be accurate up to 150 yards, though the most effective range is 100 yards before dealing with the large ballistic drop.
When shooting standard 40 grain CCI 22 High-Velocity ammo with 1235 fps, you can expect between 0.5 to 0.9" diameter shot group at about 25 yards with a 1 or 2 MOA red dot reticle.
What Distance To Zero Ruger 22/45 Lite?
10 to 50 yard zero are good distances to zero the reflex sight on a 22LR pistol. Of course the user can extend the range if they feel confident doing so.
Which MOA Dot Size To Buy?
1 MOA to 3 MOA dot size for a Ruger Mark IV 22LR pistol is adequate for getting effective hit up to 100 yards.
The bigger the dot over 3 or 6 MOA will cover too much of the targets up close for a 22 caliber bullet.
Is Mounting An Expensive Red Dot On A 22LR Pistol Necessary?
It's all up to your budget!
Mounting a super expensive optic on an almost no recoil 22LR isn't necessary in terms of cost.
