250Z New Look at Barra 270z, 300z and western revolvers at RMAC

[airgunnerd]

Is it just me or are the upgrades listed the exact same specs as the 250z barrel is 27.5in and they list the air tube on the 250z as 322cc but the upgrades for the 270 are listed as a longer barrel at 27.5 and larger air tube at 322cc???????

The barrel length and air tube volume are the same between the two models. In terms of air capacity and performance, the key change is the plenum volume was doubled over the original 250z. Because the plenum is built into the action block itself, the flow from the plenum to the valve is much greater than the aftermarket 250z plenums that screw into the regulator gauge hole. This makes the 270z have a higher top end power potential without requiring mods for those who want it, otherwise, the rifle shoots much more efficiently at lower power levels.

As others have mentioned, there have been significant changes made to the bolt, trigger, and safety. The hammer spring tension can now be adjusted without needing to remove the stock. It is quite a bit different overall than just sticking a 250z into a wood stock.
