If you're looking for the ultimate in power and accuracy from a spring-piston air rifle, without the recoil they normally produce, look no further than the Diana Model 54 Air King sidelever action springer.

One of the Diana Model 54's most unique and sought-after features is its recoilless action. Employing a set of rails on which the action hovers, Diana has significantly reduced felt recoil. This not only makes for a more comfortable shooting experience. It also improves accuracy because pellets clear the muzzle before being affected by spring vibration.

The Diana Model 54 Air King's blued steel components are wrapped in a dapper, beechwood Monte Carlo stock with a checkered forestock, grip and raised cheekpiece. With top velocities of 1100 FPS in .177 caliber and 900 FPS in .22, this spring piston air rifle is well suited for everything from plinking and target shooting to pest removal and small-game hunting.

Things I liked: I bought this rifle to shoot sparrows off my Purple Martin houses. it is very accurate! no problem hitting sparrows at a distance of 30 yards without damaging my bird houses. all of my shooting is 30 yards or less, so I can't commit on long distant accuracy. I love the fact that the gun is NOT hold sensitive, at all. and it likes the cheap Crosman hollow point pellets. I mounted a vortex diamondback scope on it and have had no problems with scope damage.

Things I would have changed: the weight of the gun might be a problem if packing it around all day in the field. I shoot from a bench in the backyard so it's not a problem for me.

What others should know: it is very pellet friendly, not much difference in any of the 5 pellets I tried. and I've read where people were concerned about the breech sliding backwards when aiming upwards, this has not be a problem. if you cock and load the rifle and then set it down stock first on the ground, sometime the breech will slide back. but you can just shove it forward again when you push the safety off.

Things I liked: Feels more compact and lighter than my HW90. Shoots faster too. Probably will use it for varmints open sights. Yesterday, I missed a 10' shot scoped on my M34. Lol. As much as I like scoped air rifles I need one without an optic that can make a clean kill at 50 yards, hopefully more.

Things I would have changed: I like dark walnut and metal old Dianawerks and Weihrauch. Yes, extra weight, but more like what I grew up on. That sidelever release is funny. I prefer the sidelever on my old Model 75 T-01. I propose Dianawerks and Weihrauch offer metal sights, the metal instead of plastic by the safety, and deluxe walnut stocks, with the accents in that white porcelain cap like on the old HW35E. Also swing swivels. I want to climb up my hunting tower safely. Make it an option. Or do a run of a few. I bet the older airgun guys will love and appreciate that.

What others should know: 53 years worth of air gunning. I dropped out for a while. I can shoot powder offgrid. Now, my gongs irritate the new neighbors. So, until my new range is built, it's shotguns, and airguns : )

Things I liked: I'm not in the habit of giving 5 star reviews of anything. But so far the.22 caliber Diana 54 has lived up to what I discovered in my research. It is very accurate, well built, and heavy. This is the first air rifle I've ever purchased, though I have owned and used many types of firearms. I wanted an air rifle that I could bench rest, hold, and shoot like my other rifles. The 54 does exactly that. If you are like me and are planning to put only one air rifle in your gun safe, you will not be disappointed with this one.

Things I would have changed: Nothing.

  • Rodney from USA asked:

    Is this gun a refurb? Other sellers have it much higher...

    • Mark from USA:

      The gun is factory new ,in the box.

  • MARK from USA asked:

    I have the RWS Mod. 54 Air King in .177cal. It is a great rifle but I am having a real problem at the moment. I have fired it several times but now it will not cock. The lever can be pulled back and ratchets back like it is being cocked but when the release is depressed to drop the bolt retainer it is under quite a lot of pressure when returning the handle to the cocked position. Additionally it does not activate the safety as it did before. When put into the FIRE position, pull the trigger and nothing. As if it never cocked. What could the problem be? Any ideas on a fix? I am the second owner but it was hardly ever used if at all. I really like this air rifle and would like to use it.

    • Mark from USA:

      The gun needs to be repaired. You have a warranty with Umarex USA. Contact them at 479-646-4210.

  • Ray from USA asked:

    I understand that the RWS 54 is a fine air rifle. However, I cannot understand why it carries a 30-day limited warranty, when other RWS products appear to carry limited lifetime warranties? Why is the RWS 45 warranty period so short?

    • Mark from USA:

      The 30 day warranty is on a refurbbed gun. The factory new gun has a 2 year warranty.
