Out of the Walther parrus magnum and the gamo swarm magnum witch is the better rifle
I would go for the Parrus.
Do these rifles have the "Stopshox" anti recoil as indicated they would in the 2016 shot show?
No, I don't believe the walther line does. I think that is just the Umarex branded guns
How accurate is it?
Billy. The shooter has to aim the gun? Really? Thanks for making me laugh. Stay safe.
Got an answer from the Consumer Services Tech at Umarex on this question. "The Parrus, like most other air guns is more dependent upon the shooter for its accuracy than the gun itself. The LGV does have a vibration dampening system that the Parrus does not, but you should be able to shoot the Parrus very close, if not as well as the LGV."
