Things I liked:This rifle is bad ass. Don't need to say anymore! Things I would have changed:The only thing I would have liked out of this gun is a larger breach, this way it could accept some of the larger eun jin pellets. What others should know:Or ordered the accessories to charge the gun through a scuba tank. The foster quick disconnenct I received was leaking air through a hairline crack, pyramyd air was fast to ship out a new one (3 days). put everything together noticed I still had a leak in my line. after looking everything over I noticed my air venturi k valve adapters bleeder valve was missing its gasket ( a little steel ball bearing), called pyramyd air. again, Not a problem, and this time they overnighted the part. Great customer service, I will be doing all my shopping through PYRAMYD AIR!
