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

This sight is very similar to the Burris FastFire 3 which we will talk about in the next section, and it features a Leupold DeltaPoint Pro alike wide field of view with automatic brightness mode that uses an ambient light sensor to control the dot intensity, which is helpful under constantly changing light condition.

The top-loading CR1632 battery access makes battery swap extremely easy without removing the whole sight like others available on the market.

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

Why this might be a better option than Trijicon RMR – The Holosun 507C is clearly beating the Trijicon RMR on sales because it’s affordable and has the same durability.

Cost-Effective – One thing people love about the Holosun 507C is it’s much cheaper than an RMR and it does the same thing, and it shares the same mounting footprint, so if you don’t have to buy a special mount for the 44 mag revolver if it already has Picatinny top rail.

Another feature the Holosun 507C has is the multi-reticle system, which allows the user to pick from:

  • 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.

For the cost of this optic, you can get almost 2 Trijicon RMR’s. The battery life is great, and you will not disappoint. Check out the link below to get the best deal on OpticsPlanet

Burris FastFire 3

The Fast Fire 3 is a hot selling micro red dot available in 3 MOA or 8 MOA dot sizes, which are perfect for PCC, sporting rifles, and rimfire guns like the Ruger 22/45.

For close-range 22LR shooting, the 3 MOA dot provides more pinpoint accuracy than the 8 MOA dot, as the smaller dot covers far less of the overall target area for more precision shots.

Top Battery Access makes battery swap extremely easy without sight removal, and the automatic time-out feature after 8 hours helps battery last up to 5 years

Super lightweight and low profile design makes it a very pleasant optic get fast on target on pistol caliber and rimfire firearms.

For 22LR plinkers out there, this is the best micro red dot for the money for anyone starting out new or experienced shooters.

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?

Ruger mark iv range testing
Image Referenced Iraqveteran8888

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?

The answer is NO from the perspective of cost and it’s very much up to the shooter if he/she wants a $600 Trijicon RMR on a 22LR. Generally speaking, an expensive sight goes with high recoil calibers.

Optic like the Burris FastFire 3, Vortex Venom, and Sig ROMEO1 feel like they will break on a 357 sig, but on a 22LR it will be just fine.

So it’s NOT necessary to have an expensive optic on a 22LR pistol, again… its all up to your budget.


Round Up

The Holosun HS407C is the best red dot sight that has the strongest build quality over others. Extremely long-lasting battery life and performance is why we’re recommending.

The next option is the Vortex Venom for its lightweight and slick feel on the Mark IV.

No matter which optic you pick you will have a blast on the range whether you’re teaching a beginner shooter or plinking, you will not disappoint.
