  • Q & A: 3 answered questions
  • Muzzlebrake
  • 5.25" long
  • .630" inside diameter
  • Fits RWS 34, 34P, 45 and 350 Magnum rifles and Beeman R-series rifles
  • Has 3 set screws
  • Front sights on the guns must be removed to attach muzzlebrake

Installation instructions:
  1. The front sight is removed, the muzzlebrake sleeves over the end of the barrel and the brake is then secured with the set screws.
  2. You will probably have to file down the grooved area where the front sight attaches for the brake to slide over the barrel.
  3. When the factory grooves the top (muzzle end) of the barrel for sight installation, there will be two raised areas that can cause the muzzlebrake to bind if you don’t file them down.
  4. You can always reattach your front sight, as only a small amount of the grooves are removed.

  5. In stock

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.

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.
