Tell us what you think
This is a great air rifle. Easy to load, hits hard, fairly economical in terms of CO2 consumption, has a good trigger and the fit and finish are excellent. The finish on the stock is silky smooth. It is very comfortable, feels light but substantial, has very good sights, and is very accurate at 10 meters. I have not used it beyond that distance. The length of pull, at 14.4 inches is about perfect for me. The stock, while right handed, is very comfortable for a left handed shooter.
I would prefer that the stock be a little wider under the barrel where it is held while shooting.
Loading the CO2 cartridges is a little tricky and is not well explained in the instructions. The first one goes in nozzle first then the second one goes in with the nozzle pointing out. When the cap is screwed in, it pierces the second cartridge and backing out the cap a small amount released the gas. The first cartridge is pierced the first time the trigger is squeezed. Once gas has been released, the cap cannot be turned by hand. My recommendation- before inserting cartridges, clean and lightly lube the threads then turn the cap all the way down. This will straighten the threads which do bind a bit and you can see where bottom is. Remove the cap, install the cartridges, ,then turn the cap all the way back down. When you back it off, it will suddenly seem to lock up. That means the gas has been released. Do not squeeze the trigger to release the gas from the first cartridge until you are sure the second cartridge is pierced.
Wood stock. Blued finish. Accuracy
Quality control and reliability . My rifle failed after just shooting less than 30 rounds. The PSI dropped significantly to about half during my very first shooting session and has to go back to Pyramid the next day. To this date still waiting for the replacement.
Nothing much to share 'cause I haven't had the chance to spend enough time with the rifle.

Verified BuyerAccurate, light, easy to use and fun to shoot. The rifle has adequate power for backyard plinking.
I would like it to have a bleeding valve for the CO2.

Verified BuyerGot it pretty fast accuracy is unbelievable killed three rabbit at bout 15 yards they dropped instantly
Nothing at this price
It’s great
Good solid feel. Wood and steel. Easy to work on.
Better quality control needed.
Didn't hold co2 right out of the box. The white O-ring on the fill cap fell apart almost as if was made of paste. Thankfully I have spares. After replacement it held gas for most of the day and then the white o-ring on the outside of the valve body gave out and dumped all the gas. I disassembled everything and replaced the o-ring and it has been holding gas with no further issues.
The barrel had mild scratches down it's length where the barrel band was originally put on. The trigger was terrible. I was able to polish and adjust it to pretty good.
These rifles are good if you like to tinker and modify them. Don't expect it to be on par with a higher grade of gun. I would recommend getting several spare o-rings for it at the same time you buy the airgun.
You will need to know how to completely dismantle this air rifle in order to replace all the inferior failed O-rings that come with it new. You will not be able to purchase them from Pyramid Air and will have a very difficult time getting through to anyone at Beeman USA over the phone. You will have to order a new O-ring set somewhere online and figure out what sizes you will need.
Better support from the seller and manufacturer.
I would not recommend this air rifle unless you are willing to take it apart and replace all the standard O-rings that come with it or have someone who can do it for you.
ACCURACY, WEIGHT & FEEL, WOOD STOCK, ADJUSTABLE TRIGGER. MADE LIKE A REAL GUN, NOT A TOY.
WENT THRU 3 WITHIN A YEAR. SEALS ARE WORTHLESS. ONE LEAKED AIR AFTER 2 WEEKS. IF YOU SHOOT EVERY DAY LIKE I DO, BUY SOMETHING ELSE, BECAUSE THESE RIFLES DO NOT LAST. ALSO BEWARE THAT THE BEEMAN WARRANTY SERVICE OUT OF CALIFORNIA IS HORRIBLE. WILL NOT PROVIDE FREE RETURN SHIPPING FOR REPAIRS UNDER WARRANTY LIKE PYRAMID AIR DOES. BUY A DIANA CHASER INSTEAD!
fit ,finish and very accurate
nothing
fun to shoot. holds tight groups at 20 yds.
Deep blue finish and flawless stock coating Adjustable trigger Balance CO2 capacity
Assembly tool mark scratches on the bluing Trigger guard screws both have damaged slots Front trigger guard screw crossthreaded and useless Bolt operation EXTREMELY rough from unpolished edges of breech cutouts Could smell the raw rubber recoil pad before i opened the shipping box.
Good value for a basic CO2 rifle, but disappointed on the careless assembly of the rifle
Great build quality and good accuracy. Best single shot CO2 rifle for the money.
I wish the rear sight was more easily adjusted.

I like just about everything with this CO2 rifle.! It very accurout of the box with pretty much all different style pellets. It not pellet picky! And for around $180 bucks the value is tremendous! Considering most pcp airguns run around $500 -$1,000 or more. Yes, this is a very basic model CO2 from Beeman, not a lot of power, but CO2's are inherently less powerful than pcp or magnum springers. I've had mine for a few months and tested the velocities from a range of .177 pellets, and here are some of the results: H&N Match Green (alloy) 5.25grains - very light, but very accurate out 25yds on non windy days. My muzzle vel. Results ith this pellet were very impressive, with an average speed of about 750 - 755fps ( keep in mind that CO2 likes warm weather 65 - degrees or higher) my tests were done indoors at a temperature of about 70 degrees. The next pellet I tested was the RWS MeisterKugeln 7.0 grains ... average velocity was about 700-708fps, again not bad for a pinker. T
Sorry ran out of room on the last chronographs review, but here are the next three chronograph Results: H&N TERMINATOR. 7.25grains = 699fps avg. H&N. Hornet. 10.03grains. = 642 fps. Avg. and the Crosman Premier " Destroyer" 7.4grains. = 688fps avg. I also test the Crosman Premier hollow points, 7.9grains averaging at 675fps. So this is pretty darn good in my book. This rifle is great for plinking cans or silhouette targets. It very accuraout to 30yds (1/4inch). And at 20 yds. Ragged one hole groups! My only suggestion is to improve the pellet loading port, it very tight, especially if you have a scope mounted . Other than that it's a winner!!
