By John from USA on 2015-07-07 19:16:44

Things I liked:

...not much, other than the looks. I have an RWS 350 Mag in .22 and I replaced the open sights with a Leapers scope. I bought this to cover up the groves for the front sight, but my accuracy at 100 ft went from 1.5" groups to 4"

Things I would have changed:

If you're going for looks, I'll admit it's sharp. However, it throws the harmonics of the barrel off, and the accuracy goes down the drain.

What others should know:

Just like a tuning fork, an air gun barrel is a tuned instrument... Make it too short, and the pellet flies out too early, and the piston slams into the end of the cylinder. Make it too long, and the pellet is still in the barrel when the piston hits the end of the cylinder, and the resulting "twang" throws your accuracy right out the window. So going back to the tuning fork, the mass determines the resonant frequency. When I put the "muzzle brake" on (really a cocking handle) the added weight affected how the barrel oscillates or "whips" Cool looking cocking handle, but if you want a small tight group, go without it and live with the groves on the muzzle.

    Fit & finish & price and the open end at muzzle !

    Things I would have changed:

    Nothing !

    What others should know:

    the open end at muzzle is what I prefer it give you a choice of leaving it that way and not having anything in front of your barrel crown & face which is good when cleaning you can wipe off the barrel crown when done or you could make a few baffles for a quieter backyard

    Things I liked:

    Looks cool, doesn't seem to change performance, 3 grub / set screws holding it on. Not gaudy, simple and seems made ok.

    Things I would have changed:

    Give it away.give it way now... Not a deep blue finish. Good enough, but not a oh la la! super machined item

    What others should know:

    My 34 Diana model had c fiber sights front and rear, also no Diana logo ( Goddess holding the gun) I have it all scoped out with a drooper mount so no need the stock worthless plastic sights. This covers the notch on the barrel end makes a nice grab to help cock. My vintage 24 has old school metal non fiber optic sights and is nice. I know you can buy this model with the metal sights, if your not a scooper get that one. Your mileage my vary but this thing was worth of for me. It gives the gun a nice balanced finished look.

    Things I liked:

    Looks, great fits perfect on my Diana 34. maybe some blue loctite needed? . Mine has 3 grub screws in perfect length. Replaced my plastic fibre-optic sight with the plastic " glow" as big as a horses leg. Good handle for cocking. less snag out of the case. Price a tad high? but not crazy. .630 ID fit my barrel good

    Things I would have changed:

    Just a fuzz of machining / de burring at the tapered end. Just a tad rough off the lathe Instructions on on where to place it on a barrel , i.e how much barrel crown to stick out over it? Or any help..

    What others should know:

    I don't buy into the accuracy loss, or the sound thing. Even the the change of whip? dynamics? It fits the bill for me. Less plastic and easier to cock the barrel. I go scope as my old eyes can't see far away. I doubt your young eyes can see far away as you can drop pellets. Looks awesome. Decent price. Shipped well and fast. What more do yah want?

  • 4.0 4.0

    5.0 5.0

    Things I liked:

    The muzzlebrake is a good value for the price. It makes cocking the Diana easier after removing the front sight. I am not sure if the brake has improved accuracy as the Diana was extremely accurate before installation.I installed the brake to improve appearance after removing the sights.

    Things I would have changed:

    Maybe a fitting to encompass the crown of the barrel.

    What others should know:

    Install with the two screws on the bottom of the barrel. File the sight ridges at the muzzle to allow the brake to slide on w/o obstruction. Blue the file marks. I used a dremel tool sander instead of a hand file.

    Things I liked:

    It fit the barrel of my Xisico XS-28 .25 Cal.

    Things I would have changed:

    It needs to be thicker, heavier and Blued, not painted.

    What others should know:

    The walls of this muzzle break are so thin that there barely any threads for the set screws. It needs to be made thicker.

  • 4.0 4.0

    5.0 5.0

    Things I liked:

    Great design (with exceptions noted below), well crafted (for the design), good material and finish. Every metal barrel break I have ever installed enhanced the accuracy and consistency of the rifle and these are no exception. I have 4 of these in operation now (2 on RWS D34s and 2 on Ruger Blackhawks) and they are doing their duty admirably.

    Things I would have changed:

    There is a definite need for an end/muzzle cover on these for both simplicity of installation and barrel crown protection. Would also be nice if installation shims were made available for smaller diameter barrels.

    What others should know:

    Lacking shims for some of my smaller diameter barrels, and taking a clue from previous reviews on these that complained about mounting screws loosening, I take a 1" wide strip of Gorilla duct tape 5" long and put it lengthwise dead center on the top of the barrel before installation. Slide the break on with the screws on the bottom and tighten them securely. After a couple of hundred rounds through one rifle, no noticeable loosening yet. I have used "Liquid Welder" and put an appropriate sized washer over the front of one of these, painted it Black and am testing it for robustness and longevity. Will report back if anything about this modification goes wrong or needs correction. If it stays on correctly, at least the barrel crown will continue to be protected.

    Things I liked:

    added ballance and handle for cocking

    Things I would have changed:

    tighter barrel sleeve and more set screws with with more substance.

    What others should know:

    when it comes loose and it will your accuracy will be off until you resset it.

  • 3.0 3.0

    4.0 4.0

    Things I liked:

    Cheap, easy installation.

    Things I would have changed:

    Better finish, include shims or sleeves to protect barrels from tightening screws.

    What others should know:

    The finish on this is poor at best. Looks good from ten feet away, but up close will show scratches in the finish.Use some sort of shim between the barrerl and the lock down screws or risk gouging your barrel.
