Your gun may be marked IZH-513M or MP-513M and may have any one of these mfr names: IZH, IZH-Baikal or Baikal. They all come from the same plant and are manufactured to the same specs. The guns are identical.
A magnum air rifle at an incredible price. The IZH MP 513M is a breakbarrel spring-piston gun that flings lead at 1,000 fps! Made in Russia, the rifle has a hammer-forged steel barrel set inside a classic wood stock.
The traditional good looks of the MP 513M have been combined with some interesting features. Once the rifle is cocked, you will not be able to pull the trigger to fire the gun until you pull back on the hammer. It also has a unique anti-beartrap mechanism to prevent the barrel from closing until the gun is fully cocked. The anti-return system prevents the barrel from suddenly closing if the trigger is pulled while the gun is partially cocked.
The MP 513M has a two-stage adjustable trigger, a fully adjustable rear sight and a hooded front sight with aperture inserts. Want to increase accuracy? Mount a scope or red dot on the 11mm dovetails (scope stop required). Good for plinking, shooting spinners and hunting small game and pests at medium range.
