You will learn all about why this is a great gun in this review.

The Crosman Optimus .177 Caliber air rifle is a spring powered air gun. As the name suggests, there are a coiled springs and a piston inside the chamber. When you cock the gun, you make the spring compress until the small hook of the rear of the piston engages into the sear. When you pull the trigger, you release the hook and force the spring to decompress. The decompressed spring makes the piston move forward and causes the air to compress inside. As a result, the bullet is propelled out of the barrel.

Spring air guns are known for their consistency in shot-to-shot basic, high power and for their impressive accuracy.

The barrel of this air gun is a rifled barrel (or spiral barrel) with grooves inside. This is designed to make the bullet spin before it leaves the barrel, which increases the bullet’s stability, improves accuracy and enhances shooting range.

The Crosman Optimus -.177 is a single-shot, break barrel air gun, which means that only one shot can be fired per trigger pull. You will also have to perform a break barrel to cock the gun to shoot again. In order to do this, you have to hold the gun close to your body, firmly slap the muzzle, pivot it toward the end of the gun, insert the pellet (with the pellet’s skirt toward you and the pellet’s nose forward of the barrel), and swing it back into its original position. This may take some practice at first but when you get used to it, it will become second nature.

This air rifle has an internal diameter of 0.177 caliber, which is the most common caliber with air guns. This calibre is the top choice of consumers as a cost effective plinking/shooting gun since the ammo is very cheap.

The Crosman Optimus 0.177 features a beautiful, brown hardwood stock, which gives the gun a well-balanced, sturdy feeling and classic look. The stock is also ambidextrous so you can train both shooting arms or switch off with an opposite-arm shooter in practice. A thin plastic pad at the bottom end can allow the gun to be stood up for added convenience. The stock also has a rubber pad at the end of it to help absorb recoil from the kickback. This particularly useful because this gun has a higher recoil rate.

crossman optimus 177 ammo

The Crosman Optimus 0.177 uses any kind of 0.177 pellets as its ammo so you can use different pellets depending on your needs. For example, if you want to shoot paper targets or practice plinking, the flat head (or wad cutter) and round nose pellets are great options. For hunting or small varmints, you should use a pointed pellet or a hollow point pellet.

crossman optimus 177 velocity accuracy power
Crosman Optimus .177 barrel

The manufacturer claims that the Crosman Optimus 0.177 air rifle achieves a velocity of 1,200 feet per second (FPS) with an alloy pellet and 1,000 FPS with a traditional lead pellet. These are shocking numbers for an air gun, considering that these velocities would break the sound barrier. However, upon further research, it seems that some customers report a lower FPS than what is reported by the manufacturer, in addition to being a very quiet gun. 

Customer velocity tests show that with 8.3 grains RWS superdome, 10.2 grains JSB Exact dome pellet, 8.4 grains JSB exact dome, Crosman primier 7.9 grains, and 10.5 grains Crosman Priemier, the air gun has an average 930 FPS, 807 FPS, 877 FPS, 923 FPS, and 759 FPS, respectively. The highest velocity attained with this air rifle is 1,138 FPS with the RWS HyperMax pellet. Together with the FPS, this air rifle has about 13 – 16 foot-pounds of muzzle energy (FPE; i.e., the kinetic energy of the pellet when it leaves the muzzle) with the pellets mentioned above. So while the truth may disappoint supersonic-speed seekers, remember that the FPE this air gun produces is more than enough to take care of small varmints such as rabbit and is still impressive for its price range.

All of the numbers above shows that this air gun is extremely accurate for short, medium, and long range shooting.

For example, the common shooting group at 30 yards is 1 – 3 inches, so you can easily hit a nickel or a quarter at 30 yards or less. Moreover, many people can hit a tin can at a distance of 100 yards with an open sight – yes , they don’t have a problem getting accurate shots EVEN without the scope. Others can take down a woodpecker at 50 yards.

The trigger safety is undoubtedly easy to use: pull it back and your gun is locked, pull it forward and you are ready to fire. The trigger itself is designed effectively so even kids with small palms could grasp the trigger with ease. If you don’t like the plastic trigger that it comes with, you can replace it with an aftermarket metal trigger for a low price.

crossman optimus 177 Sight
Crosman Optimus .177 sight

The Crosman Optimus 0.177 has an open sight with a fiber optic front sight and an adjustable rear sight. Fiber optic sight is the use of optical fiber for the dots. It gathers and channels ambient light to the rear sight in such a way that it is brighter than the dark surroundings. Fiber optics is much better than conventional sighting where you may have a hard time making sight alignments to the target. With a fiber optic sight, you can easily get a more precise aim even in low-light conditions. Furthermore, the rear sight of this air gun has windage adjustment (can be adjusted right and left) and elevation adjustment (can be adjusted up and down). Having both of them gives you the ability to adjust your point of aim in a precise manner.

Crosman Optimus .177 scope

This air rifle has both an open site and a 4x x 32mm centerpoint scope. The 4 x 32 scope is designed to help you achieve high accuracy in long range shooting. If you’re not a fan of a 4 x 32 scope or if you have perfect vision, you don’t have to use the scope for short- and medium-range shots (up to 60 yards). The scope will be handy after 60 yards. 

crossman optimus 177 loudness

As I said earlier, most customers agree that this air gun will need some time to break-in before it quiets down. After about 100 shots, this air gun is really quiet and won’t bother your neighbors as much.

crossman optimus 177 shooting ability

The Crosman Optimus 0.177 is great for target shooting, small hunting, and small and large pest control. With the open sight and 4 x 32 precision scope, it has a very flexible range. It is excellent for 30 yard shooting, great for distances of 30-50 yards and is fairly accurate up to 100 yards.

crossman optimus 177 customer review

When researching products, I always look for trends in customer reviews to see if any issues could arise. Most customer reviews about this air gun are positive: they love its gorgeous look, classic design, straightforwardness, high accuracy and power, quietness, great open sight and decent scope. Some find it very accurate out of the box and some find it takes more than 100 rounds to stabilize the noise and achieve consistent shooting groups. The customer rating is very high, with 4 stars (85% of the overall rating) on amazon.

crossman optimus 177 price

The Crosman Optimus 0.177 is very affordable at around $100. Considering the prices of other air guns that feature similar velocity and power, owning the Crosman Optimus 0.177 is like you get the 4×32 scope for free. This is definitely a great air rifle for the price.

There are a couple of different listings with different prices but the listing I found with the lowest price is even cheaper than the price on manufacturer’s site or the prices on other e-commerce sites.

    I simply do not not agree with Steve. (( Steve’s Reviews))

    The scope is useless in that it will not properly focus regardless how far the adjustments are moved in either direction. I replaced it with an inexpensive Simmons scope, and that scope is clear and useable.

    The biggest problem I have with this air rifle is the trigger. I am 76 years old, and bought it so I could hunt squirrels with my grandsons. I have hunted for about 60 years. I have 7 rifles of various calibers. I reload 5 cartridges. I have hunted in Alaska 6 time, Canada 3 times, western and southern states about 20 times, and hunted deer for 55 years, since I was 21 years old. While in the military, I qualified as an expert with open sights. With a good rifle, AND SCOPE, I CAN STILL SHOOT AS WELL AS THE YOUNG GUYS. I am not lacking for experience.

    Both of the air rifles my grandsons have have excellent triggers on them (another brand), so “I know what I’m talkinhg about”. ~~~~~~~~~~ THE TRIGGER ON THIS AIR RIFLE IS BY FAR THE WORST TRIGGER I HAVE EVER USED. TURNING THE ADJUSTMENT SCREW CLOCKWISE IS SUPPOSED TO INCREASE THE CREEP BEFORE IT FIRES, AND COUNTER CLOCKWISE IS SUPPOSED TO REDUCE THE CREEP BEFORE IT FIRES. TURNING THE ADJUSTMENT SCREW ALL THE WAY TO COUNTER CLOCKWISE DOES NOT REDUCE THE CREEP AT ALL. THE CREEP IS SO LONG THAT I NEVER KNOW WHEN IT IS GOING TO FIRE, AND AS A RESULT I FIND IT IMPOSSIBLE TO CONSISTENTLY HIT EVEN TARGETS WITH IT. ~~~~~~~~~~ Is there a simple fix for the “LEMON TRIGGER” that is on this Crosman Optimus, or is there an aftermarket replacement trigger that will allow the rifle to fire when the trigger is initially pulled?

    • There is also a simple fix for other readers that has this gun.

      Leave the adjustment screw alone and open the gun.

      Once you remove the stock you will see there is a type of spring that result the trigger to be very hard for some and unpredictable.

      Remove the spring(keep it for in case)

      Once i have done this the trigger was much lighter(careful it takes a few shots to get use to this…)
      and releases on the same spot every time…

      If you are unsure there are a bunch of vids on youtube just search for
      “Crossmann optimus trigger fix”

      Had the rifle for about 3 years now and still going strong!!!
