I have been shooting this gun for almost a year now and I have shot a lot of ammo through it with out a single problem you just have to use the right pellets.

I love the magazine and how you can store a extra magazine in the handle where they have the tool stored for changing the co2 cartridge absolutely genius


By TheodorUSAAugust 30, 2021 Verified Purchase

I called a customer service and they are very professional and they take care of me

Great gun

By TedJuly 27, 2021 Verified Purchase

They have to take the gun back and give me a new one

Used it just 3 times The 3rd tome co2 gas leaked out and was gone in 3 second I called airgun depot they gave me the factory number the phone number is disconnected ???


By LamonteUSAJuly 22, 2021 Verified Purchase

I bought this gun back in March of 2021 and haven't been able to use it since late April of 2021 due to all of its malfunctions I would not recommend buying the Webley nemesis, it's a waste of money..

It's a very good-looking gun but that's about it

The seal will give out in a very short period of time causing CO2 to have massive leaks and also the gun tends to jam all of the time

By FrederickUSAMay 21, 2021

If you must have a Webley, wait for a new model.

I’m re-reviewing after taking this out target shooting three times. Probably got a total of 70 rounds before the CO2 seal malfunctioned.

CO2 seal failed on the third outing. Cylinder just gushes gas out around the puncture end and internal seal intended to keep the CO2 in the mechanism. Further, these overly expensive magazines are a pain in the a## because they’re difficult to insert and remove, plus it jams a lot. That’s a real pain.

By FrederickUSAApril 29, 2021

Thought this would be a good addition to my pistols. Sadly, it does not perform well at all. It’s clever how the magazine and CO2 compartment tool fit into the bottom of the grip. The gun looks good and feels solid enough.

The add-on magazines (a two pack) with shipping and tax are 1/3 the price of the pistol. Pellets jam A LOT, cutting down on shooting time. The magazines are very difficult to slide in and remove. I’m only getting 18 to 24 shots per CO2 cartridge and that is far less than manufacturer specs. I don’t recommend this pistol. It’s just too difficult to set up and use. Is it accurate? Yes, very. Too bad it has so many quirks.

By FrederickUSAApril 2, 2021

Don’t be tempted to own this. It looks so much better than it functions. You’ll definitely need a small tool kit when you go shooting this thing. All is my opinion from having used the pistol.

Pros: 1) Looks very nice.

Cons: 1) Not well balanced. 2) Magazines difficult to insert—very tight fit (use a dab of oil on mag groove). 3) Jams a lot on just about any .22 pellet. 4) When jammed it’s nearly impossible to free the magazine. 5) Jams misshape the pellet body and you’ll need a small pointed tool, or long rod to push pellet out. 6) Sights are way off. You can aim in the direction of Canada and the pellet will end up in Brazil.

The Webley Nemesis Co2 pistol looks and feels solid. Unfortunately it died after just one shot. All the gas leaked out, and the bolt spring broke. I was disappointed after having bought this pistol as a gift for a friend.

The gun looks really cool. The two rails are good for mounting accessories.

It doesn't seem to work at all. Maybe it was a fluke, but I would not buy this gun again.

By TimothyUSAMay 10, 2019

It shoots on target, and has a good trigger. I got 2 of them, both shoot great.

By JAMESUSAApril 29, 2019

I somehow got the impression that this was going to be made in England when I read some pre-production press. I was disappointed to see the dreaded phrase that is applied to what seems to be the origin of 90% of the world's goods. The Nemesis is very largely made of polymer but it is sturdy and has a very nice appearance of quality. The only steel or metal I could discern was the actual barrel, breech bolt, inner firing components, valve and the CO2 housing well. The sights are fiber optic (not a desirable feature to me) and both front and rear are windage adjustable. There is no elevation adjustment but my sample shot to point of aim. A full length dovetail rail runs atop the barrel housing and breech and a Weaver under-frame rail is present as well. Trigger pull is smooth and light with a crisp release; the bolt operates very easily and smoothly and the magazine in all aspects is pleasant to use. I measured velocity with slow fire, pausing a minute or two between shots so that I could determine a true measure of its velocity over the entire number of shots per cartridge. My pistol is the .22 cal. The first 30 shots were all full power with no trend of decrease and averaged 391 fps (high 397, low 383) with the JSB 14.35 gr.Jumbo Express dome. At shot 31 a slow decline in velocity began but still no shot was less than 375 fps. At shot 36 velocity began to drop steadily with each shot and I stopped the string at shot 42 which was down to 337 fps. The average group size with the open sights was 3" at 20 yards. The addition of a SightMark Sure Shot Plus reflex sight produced 4 six shot groups averaging 1.035". All 24 shots of the four groups were only spread over 1.181". The reflex sight required a conversion rail to provide a Picatiny base to mount it upon. I used a Hammerli 850 Magnum rail cut down to the length of dovetail behind the loading port and secured with the screws moderately engaging the polymer receiver. The rail had to be kept level to keep it from canting during the mount. Once secured correctly, I anchored it with a small amount of epoxy at the four corners of the rail between the dovetail and rail. Once cured, this provided a very solid and secure base for the sight.

Fine 20 yard accuracy with the aid of a reflex sight. Very smooth operation of the safety, trigger, breech bolt and piercing assembly. The power level was a little better than the rated velocity and using slow fire velocity was very steady for 35 shots. A very nice looking pistol

Made in China. Polymer dovetail rail may not provide a reliable foundation for some conversion rails to Weaver/Picatiny to allow mounting of most red dot sights. Do not try to tighten conversion rails using top mounted set screws too much (side mount clamp type conversions are a better option) and I added the epoxy as described to secure the mating of the two making my addition pretty much a permanent alteration. The accuracy improvement and my disdain for fiber optic sights made that a painless choice.

What are the thread requirements for using it with a diffuser, a faux silencer, or similar?

asked Frederick from USA

Hi James W. Thanks so much for your detailed review. The only news I can't find are the actual joules of this gun (the .22 one). Possible they are a little less than four joules? I live in Italy, where there is a 7,5 joules limit. If I am right there are no problem taking this gun. Best regards, Sergio G.

asked Sergio G.

Does Airgun Depot sell extra mags?

asked Robert from USA

Yes, they sell a pack of 2.

Walter from USA

Looking for lead-free pellets for a .22 caliber version of this gun (lead-free preferably); any suggestions on what would fit the magazine?

asked ChiMaster

how long will the co2 stay in the gun without leaking out

asked Timothy from USA

I suppose it comes with 1 mag. Are extra mag available to buy?

asked Daniel from USA
