do NOT purchase these thinking they are real Diana 240s - they are not.

the only "pro" is that it looks like a Diana 240 from a distance

These are trash Chinese knock offs. The older German made 240s were great, however these are now counterfeit "Model Two Forty Designed by Diane". Might be worth $60 retail. I'm sending these back immediately. The triggers are terrible, the parts do not interchange, they are LOUD and inaccurate. Airgun Depot knows they are Chinese (it's printed on the box) yet still selling these as Diana 240s.

It is a very high quality piece, and a very low price. What's to say?

Easy cocking motion, shoots well after a hundred rounds or so. Neighborhood friendly, it is exactly what I wanted for backyard plinking. Gun is more accurate than I am.

Well, 2. Lower bolt was very loose, and actually fell out while I was shooting. Once I tightened up all bolts and screws, it started to shoot accurately. Also, rear optical sight was broken in half on arrival. But, full credit to Airgun Depot, a quick call, an emailed photo, and I had a replacement in three days. Could not have been easier (also, I use the scope, not the very nice optical sights.)

By TravisJanuary 3, 2020

This is a nice, lightweight break barrel with the best trigger in its class. It cocks very easily, so a nine or ten-year-old boy will be able to cock it and it is very easy to shoot in general. Not much power for anything but plinking and shooting very small pests, but it is a great beginner gun, and even if you have a lot of airguns you may still appreciate this for its reliability and ease and fun of shooting.

Lightweight Easy to cock Great trigger Good accuracy

Low power (but that's what makes it so fun to shoot!)

The fit and finish on the air rifle is perfect. It is very well built, well designed, and very accurate. Ruth at Air Gun Depot was very knowledgeable and helpful when I had a question. This is now my favorite air gun.

Very high quality. Great price. Fast shipping.

First off this gun is VERY accurate for its price. At 10yrds dime sized groups are doable with everything stock and economy pellets. My one complaint is the rear sight. There is an adjustment screw that is held at tension with a spring that lays under the sight its self. If you press down on the sight or bump it the spring compresses and the TINY ball bearings that lay under the adjustment screw simply fall out. This is extremely annoying and pretty easy to do. Secondly the adjustment screw its self (at least on my gun) has to be screwed out to the maximum setting and on more than one occasion has jumped out during cocking. I am getting some aftermarket optics to put on it, and trying a lighter gr pellet. TL;DR Gun is very accurate, rear sight is poorly designed. Consider light <7.5gr ammo or aftermarket optic.

-Gun is very accurate. -Mechanically feels very sturdy. -Easy to cock -Quiet shooting

-Rear sight is poorly designed and is impossible to sight in with pellets 7.8 gr or more. -Butt stock is plastic and easily slips while shooting.

By DarrenUSAFebruary 28, 2019

Nicely crafted stock. Deep blueing on all metal T he triger is plastic but very crisp pull and release. Very happy with all aspects of the gun. Great for target practic and very accurate.

Triger,stock and build quality.

Some plastic parts but to be expected in this day and age.

First let me say that I am a springer kind of dude and I own a Diana 34 that I have been tweaking on for several years. I have become very adept at accurizing all kinds of guns and I learned much of it working on the 34. But, as hard as learning curve was, the 34 is now shooting lights out like many of my guns. With that said, I wanted to try a lower power gun for indoor shooting and felt like I had the Diana tuning thing down, so... Shoot about 250 pellets, take it apart, clean and re-lube to my specs, polish critical parts, add a thin sleeve for the spring guide, touch up seal, debur and soften sharp edges, polished a couple of trigger parts, re-crown barrel to my liking, bed stock with my special foam, CLP the ball detent spring (IMPORTANT), lube other pivoting parts, [NO DINO LUBE IN/AROUND/NEAR COMPRESSION CHAMBER!!!], Vibratite all the screws, go to sleep - it's 1:00 AM. Wake up, shoot 50 more pellets, get chrono reads, mount UTG 4x32AO scope using RWS drooper mount, shoot 200 more, solve scope mount moving [just buy a good BKL mount and forget the stop pins - don't ask], test pellets, test stock torque values, back and forth, test barrel hinge torque values. Study pellet patterns and behavior, guesstimate harmonic curve (part art, part science), settle on final pellet and stock torque (JSB Exact RS - 10 in-lb front and rear), make final tweaks, shoot final groups, go inside because it's pretty much dark. Final groups with JSB Exact RS were 2x 2-shot groups at 13 yards that both came in around .14"followed by 1x 2-shot group at 18 yards that was around .4", NOT adjusted for a 6 MPH cross-wind. Sorry I couldn't shoot more, but it was dark. However, this is pretty representative of what I was seeing all day while I was tuning. Love it. Very happy and will enjoy the reduced weight shooting indoor silhouette.

Out of the box it was a good shooter with the JSB Exact RS, H&N FTT, JSB Exact 8.44, Crosman Premier HP, and several others, though it wasn't real fussy about any of them except the RWS Superdomes. JSB Exact RS chrono'ed at 827 fps. The weight w/o scope is light and is very easy to hold and shoot free-hand. Quality seems very good and consistent with my other Diana. Average group size out of the box with virtually no tweaking was around 1.5" at 10 yards. Recoil is lighter than my 34. It was on sale for $119, yeah baby!

Front sight was twisted slightly out of the box and the rear windage had to be adjusted way left - until I figured out I could just twist the front sight back where it needed to be. Like my other Diana, it needed some TLC and tuning to become "shooter". Also, it does not come with holes for the scope stop pins and I spent a few hours fighting a problem with the POI shifting traced back to the one-piece RWS mount microscopically shifting during recoil. I made my own stop pin holes - very expertly - and the problem disappeared. Out of box, and through about 250 pellets, the recoil was light-moderate but harsh and had the usual "twanginess" of an un-tuned springer. Ball detent almost seized up after several hundred pellets and closing barrel was really difficult AND it actually started to "pull" the detent retainer from the main tube - a little bit of CLP down around the detent spring and tapping the detent retainer back in solved that and it closed just fine afterward (and the accuracy got better).

Right out of the box, I could see rust forming on the surface of the barrel. I quickly took a soft cloth and lite Ballistol (oil)and wiped it down. I could clearly see a finger print in rust. Most of the rust came off, although it still "feels" rough where the finger print was. As the photos show, there is some pitting on the barrel that was hidden by the stock. Unfortunately, that damage cannot be fixed with oil and a cloth. I don't know where these were stored, but they have a moisture of humidity problem. I have not fired it yet. Seems like a cute little rifle. I'm going to do a more detailed review on my favorite form.

Price. It was on sale.

Rust on a new rifle!

By ScottUSANovember 3, 2018

I'm 55 years old and just started to get into air guns. I bought the Diana 240 based on its reviews and price point. It was a good choice. The product has impressive quality for it's price and it's teaching me how to shot. I have a lot to learn and I'm glad I'm doing it with the Diana 240.

Exceptional value.

Front sight seems a bit flimsy.

By ChadUSAOctober 29, 2018

Purchased this gun for my 6 year old Grandson. The gun has a very nice stock, it cocks very easy, and it's a very accurate little gun. We haven't put a scope on it yet just using the open sights but it's not a problem shooting tins at 25 yards with the open sights. The very fine windage and elevation adjustments make it very easy to sight in. The fiber optic sights are very easy to see I do wish the front fiber optic was a bit smaller in diameter. The trigger is surprisingly nice for a gun in this price range as well. All and all this makes a very nice youth rifle.

Fiber optic sights - Nice trigger - Easy cocking - Very accurate - Nice looking stock

Front fiber optic sight could be smaller in diameter
