Things I liked:Workmanship. "Fixed" barrel and sights. I opted for Nitro Piston Conversion. Result was recoil in rifle smoothed out a little (time will tell if good choice. Things I would have changed:Change plastic safety to metal. What others should know:Do your homework before buying. Pyramyd Air Tech Spt is excellent source (and patient with numerous questions). Rifle is stout and requires leverage (strength) to cock, aim & shoot; exactly what I researched it to be. Balances nice for aiming.
