Notes:
This rifle has all the potential in the world to be a really accurate airgun.  The form and feel of the stock is one of the best I’ve tested in many years.   However, all the potential in the world does not help if you can’t see the target.  The factory scope is terrible and basically unusable at 10 yards.  This test was conducted with the Leapers / UTG 3-12x40AO scope.  Also, the trigger is long, pulls hard, and is not smooth whatsoever requiring a lot of discipline for bench shooting. Even with the above issues, which can all be resolved with 3rd party options, this gun is a serious contender and should be seriously considered for casual shooting in the back yard, target practice, and light pest control & small game hunting.

*Max DB is measured across multiple shots while indoors. The stated
DB is the loudest shot recorded by our equipment. Results are measured
using an industry standard DB meter and are for reference purposes only.
**Due to changes in manufacturing, we state that this is the best pellet
as of the date of testing. This is subject to change.
