Good backstop. There is really not much to complain about except what bothers me is that some remains diabolos hang so firmly to the pigs that you find it difficult or impossible abbekommt with your fingers so that you have to look for other resources to the diabolos abzubekommen. What I have noticed is the only shot with Diabolo you upsets the pigs, it did with a steel BB gun tried balls with BB, but there the pigs are not overturned. Did it with a 3 Joule CO2 pistol tested with steel BBs. But shot with my Baretta pistol with CO2 Diabolo it works properly. Otherwise the bullet trap makes a good impression, good processing. 4 From me there out of 5 stars ...!
