Hello I had a Barrage basically same gun different stock. Had it for about a year and probably put 3000+ rounds thru it with NO mechanical or air leak issues. BUT I did have issues with the magazines not indexing correctly. I took the mags apart increased the spring tension and shaved the, (for lack of a better word) the mag cylinder as to prevent it from indexing on the material that separates the pellets (almost like cutting a feed ramp in the side of each pellet chamber in the cylinder). All in all the gun shot well, it was heavy and very long, as at the time I was using a Donny fl Emperor (work very well quieting it down though). The gun was accurate enough as I bought it as a semi auto plinker( 1 inch at 25 yds with Poly Mag shorts, soda cans at 50 yds, Optic was a Vortex Spitfire 1X). It was an early gun when they first came out so I think they have fixed the mag issues at this time. Hope this helps if you have any specific questions just ask Eric
