Vortex Venom

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.

Holosun 507C X2

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.

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.

Common 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?

When zeroing the red dot sight for the MARK IV 22/45, 25 to 50 yard zero are good distances to zero your reflex sight.

Which MOA Dot Size To Buy?

1 MOA to 3 MOA dot size for a 22LR pistol is enough 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 zine bullet hole.

Is Mounting An Expensive Red Dot On A 22LR Pistol Necessary?


It's all up to your budget! 

Mounting a super expensive optic on a 22LR isn't necessary in terms of cost, but buying one doesn't mean it can't be used on other guns.

We tested these optics on various guns including shotguns, and optic like the Burris FastFire 3 can handle recoil just as good as a Trijicon RMR.

Wrap Up

The Holosun HS507C is the best red dot sight that has the strongest build quality and best price over others. The second option will be the lightweight Vortex Venom.

No matter which optic you will not disappoint!
