No, Ive looked into Real Steel ones, and without serious modification, It wont fit.

Shot for shot, its very inconsistant. The primary culpret is again the shells, I find that they are only "fairly reliable" out of the box undamaged. Once cycled, dropped etc etc The shells become very inconsistant at best. The Orings inside the shells are most likely the cause of your problems.

Edit: Mine was the spring version. I never tried the gas cylinder, but considering the size of the bolt, I dont see how you can really shoot more than a clip before having to gas up. Either Carry multiple "gassed up" bolts on you or a propane tank. Neither which I see are viable options.
