Description

The Umarex Prymex Break Barrel Air Rifle delivers surprising performance and features at a very affordable price from a respected and dependable manufacturer. It is capable of velocities up to 1100 FPS with alloy pellets and 1000 FPS with lead pellets, both in .177, which yields the necessary power and accuracy for pest control, small-game hunting, and plinking.

This air rifle features a gas piston powerplant that provides shooters with smooth and consistent operation regardless of temperature, with less noise and vibration for improved performance with lower recoil. It can be left cocked longer than a traditional spring piston, and it does not suffer from spring fatigue, so it can provide years of trouble-free use that will not degrade over time.

The Umarex Prymex utilizes a lightweight all-weather polymer stock that makes it easy to carry for long periods, and it has a textured pistol grip and a textured and grooved forearm for a stable hold. For precise shots without needing additional equipment, this air rifle offers several options. It includes a hooded fiber optic front sight and an adjustable fiber optic rear sight. In addition, it comes with a 4x32 scope that attaches to the 11mm dovetail optics rail.

To get an air gun that offers flexible features with a focus on providing high value at a low price for small-game hunting, plinking, and pest control, buy the Umarex Prymex Break Barrel Air Rifle at Pyramyd AIR today.

It's got some zip, probably take an opossum with a good head shot. Very inexpensive. Fun plinker or something to carry in the back of the car or behind the truck seat. Likes cheap Apollo pointed pellets.

Shot strings are not consistent with accuracy. More flyers than I like.

I think it's worth the money. Mine is in .22.

I have the Prymex in 22 and 177 , this review is about the 177. The rifle is light weight, powerful and accurate. I haven’t put a good scope on it because I have been able to hit with open sights a 2x2 inch metal plate at 20 , 30 and 40 yards. It has given me one inch groups at 13 yards with open sights. The best pellet I found that is giving me this accuracy is the HN 8.64 dome. With this same pellet I’m drilling holes in a piece of galvalum gauge.26 at 12 yards, they go through as if it were butter. I think I got lucky with this Prymex in 177 because the trigger pull , though not light weight, was not a beast to pull like the 22 ( l had the trigger tuned on the 22 and it’s ok now) as for my 177 it’s tolerable to the point of plinking, but not for the Olympic. The 177 is a lot of fun to shoot, and because of its size , weight, polymer stock a great gun for backyard pest control, in my case specifically iguanas. I’m very pleased with the purchase,

Umarex has a video advertising the Prymex with a adjustable trigger this is not true. The advertising department definitely did not tam the stock off , shoot it or look a the trigger housing. It does not have an adjustable trigger. That doesn’t mean it’s a bad gun , you get a good gun and maybe a hard trigger pull that can be fixed.

The scope that’s included is really basic , maybe you like , maybe you don’t , anyhow try it out. I will be passing the Prymex 177 through a Chronograph , expecting good numbers , let you know soon .

Rony Feb 07, 2026

Rony : I tested the velocity of the Prymex 177 on my Caldwell chronograph and it’s shooting the HN 8.64g at around 1,100 feet per second, foot pound energy is close to 25 fp , that’s a bunch of power for a comparatively small and light weight air / nitro piston air rifle. The best thing , and very uncommon with lightweight rifles like the Prymex is the fact that it is accurate, at least mine , in ranges from 10 to 40 yards , distances that are very common in backyard pest control. This is NOT the 11.5 foot pound air rifle used in England to do pest control, the Prymex over there would require a license. Of course the Prymex is not a Field Target rifle, but that’s not what I was looking for , I live in an island, Puerto Rico, plagued by millions of iguanas that destroy agriculture, flora and fauna . The drop like bricks , with one well placed shot with my Prymex. Hope they keep making them, great gun for Florida iguanas. Light, powerful and precise. Thanks Pyramydair .

My Prymex is a 22 . The rifle is well built , good materials , plastic and metal. Power is reasonable for pest control. It is lightweight compared to other air rifles in its power category. This makes it very maneuverable. Good grip and positioning. Good looking gun.

The trigger pull on mine is very hard , to the point of hurting the trigger finger after multiple shots. I’m not a nitro piston fan , this rifle is harder to cock than a springer , and the power output is not higher than a springer. If it weren’t for the very hard trigger pull on mine and no trigger adjustment, I would have bought it in 177 also. I took the stock off and the trigger cassette is very well built, excellent materials. The stock is not solid , but it’s not flimsy , packing is not a bad idea.

The Prymex in 22 is a nice gun , it’s not heavy and with a decent scope, say a center point 3-9x32 , you can get one inch or less groups at 15 to 20 yards. The trigger on mine has an extremely hard pull weight, and it is NOT adjustable. That alone makeup for bad precision. I sent my Prymex 22 to an Airgun smith to work on the trigger pull. The fps with 14.3 is close to 700 NEW. The scope is a joke , but what can you expect for a rifle that cost $150 shipping included. I’m hopping to be able to get this rifle to shoot better with a lighter trigger pull , even though I have made some good groups , but after a while my trigger finger is aching! What a pity , such a nice gun . A good part of this hobby is getting the rifles to shoot better , it’s a challenge, and it’s fun. If you like challenges , good luck .

I have been using this rifle in 177 and 2 to hunt iguanas , the gun is really powerful, accurate and lightweight. If the trigger were as light a pull as the Diana 240 ( another Chinese rifle) the Prymex would be in the league with the HW 95 and the Diana 350 , 177 and in this last case just as powerful. Real pity the trigger has such a hard pull , something that affects accuracy.

Rony Jan 20, 2026

The Prymex does NOT have a two stage adjustable trigger, as advertised in the video.

Rony Jan 20, 2026

It’s Rony : I got the trigger polished and lubricated , now it has a first stage that stops gradually, then a slight pull and the shot is off. Precision and accuracy have been elevated to that of a Diana 34. As for power I’m getting 16,70 fp with the Crosman premier 14.3 domes , less than 1/2 inch groups at 15 yards , and hitting a 2x2 inch target at 30 yards with complete ease. I’m using a 3-9x32 CP scope, double screw medium mounts. Knock down power : killed an 8 plus pound iguana at ten yards with one shot , fell like a rock from the tree. Conclusion : ordered the Prymex 177. Best Chinese workmanship I’ve encountered, and I have a B28 Xisico , the Prymex has better materials and workmanship. If you are up to working on the Trigger it’s a great purchase.

Solid built rifle that’s great buy at price point. Lightweight is a plus.Great accuracy.(recently put 4 out of 5 shots through one hole at 11 yards.Fifth just outside-with “iron sights”.) Have found several pellets that group well. Doesn’t seem overly picky with artillery hold or pellets.The shape of stock seems to help with trigger pull and recoil. Just the Best Buy in a breakbarrel in my estimation.

If one thing I would change it would be the front sight hood.And I did. The original is too small and walls too thick. Obstructs sight picture too much. I own 3 of these rifles, 2 are scoped and this one is dedicated to “iron sights”. May become my favorite!

Best accuracy has been pulling stock to shoulder tightly with my left hand (I’m a lefty)while a straight back pull on trigger with finger tip. Right hand just cradles rifle at balance point ahead of trigger without gripping. JSB 18’s,H&N Baracuda Extreme, and others group well but each rifle may be different . My best (and one hole is good enough!) are the JSB Hades 15.9 gr. The front hood was made with 1/2” copper pipe connector and painted flat black. Cut 1/8” slot and spread to slide in place. Top cut to light fiber optic. Will try to send pics.

Very accurately, light, powerful for both calibers love the scope, non existent trigger travel, very user-friendly 18" barrel pretty much, no recoil. And the amazing price for it and its gas piston, which is amazing for that price.

Better rear iron sights cuz i had to design and calibrate and 3d print an fixed rear iron sight for 30yds after that i never had problems again also add a picatinny dovetail combo mount for more optic options

It is hands down the best break barrel pellet gun I've ever had and for that price you can't go wrong and Surprisingly, I was able to get the provided scope to be extremely accurate.Also, the twenty two caliber version is amazingly accurate at a hundred yards with crosman premiere Hollow point fourteen point three pellets i was able to hit exactly dead on at 100yrds with no wind let's just say I spent a lot of time at the shooting range experimenting and shooting lots of rounds to get familarized with it. But this isn't my first rodeo.

Affordable, Powerful, accurate enough for my needs

I wouldn't bother including a scope. I couldn't get mine to hit an 18" square target at 20 yards. Took off the scope, eyeballed the adjustment on the iron sights, and I'm slapping the target.

Mine likes Crossman round ball and the Apollo pointed 15.4 grain. Copper spitzenkuegel pointed pellets are all over the place as are h&n silver tip.

For the price it is a well made gun , good materials and finishing. The price is very good. But don’t expect a field target rifle for the price. It’s a good air rifle for eliminating small pest . The trigger is not ajustable and it’s heavy , definitely not for long bouts of plinking.

Plastic stock for wood , the gun has plenty of power , the stock is too light.

It’s not a bad gun. You can use it it with open sights , but mine seemed hard to use that way. A good scope like a center point 3-9x32 will do the job. It’s powerful enough for small pest and iguanas. The only gripe I have about my Prymex , bought at pyramid, is the trigger pull, mine is very strong. Anyhow I can get quarter size groups at 18 yards with inexpensive CP 14.3 domes. I’m happy with the purchase of this gun , and i recommend it . Pyramid is a good place to buy Airguns .

Great deal on a good performing NP

Trigger a little stiff but not bad with practice.

After 1500 plus different pellets in .177, I found that .177 round ball ammo groups closer and are more forgiving on how I hold it. Actually round ball ammo is all I use now. 60 years shooting air guns, great value.
