For both the 250z and 270z, you will need to bleed the air tube pressure well below the regulator output pressure before you can then adjust the regulator downward. To me, degassing a rifle to zero is the best strategy for this style of externally adjustable regulator. You can then set the...

Tested and played with them so much that it feels like a job :ROFLMAO: I'll have to say that JSB pellets are far and beyond the ticket to immediate joy with the 250z and the 270z. No surprise there, that is what the factory uses for their barrel related processes. That said, many of the factory...

The .25 270z will have no problem hitting 950+ fps with properly fitting 33 grain ammo without needing anything more than some regulator adjustment, possibly a little messing about with the hammer spring adjuster. I got a solid two mags and some change on that tune across multiple stock rifles...

Unfortunately, I haven't. Between the size of my current personal collection and all the airguns I have to deal with from work, I don't have the room or time to add more. Going to have to wait until I retire to add more to my personal collection.

Thanks, I'm liking the HAMlet! No, that new pumper was done by a different company.

I wanted to give you guys some tips and tricks for setting up your 270z rifles as well as a couple of other things you might want to be aware of along the way. For those who don't know, I work for Barra, and am heavily involved in the development of Barra products. As part of my job, I've set up...

A complete top end swap is what you want to do. Put the entire .177 top end (assembled breech and barrel) on a second gen gun bottom end. There were changes made to the gen 2 breech that are incompatible with gen 1 barrels. The .177 was dropped in gen 2.

No, there is space between the muzzle and the end of the shroud in the US guns. The barrel is centered in the shroud with an air stripper. The first hiccup you feel is going into the air stripper. The second is the when you enter the barrel itself. The space is intentional, it allows the...

From a practical perspective, the hammer generally runs out of steam going past 2500 psi in the stock configuration regardless of the hammer spring setting. Power starts to retrograde past that without modifications. Like Bladefin said, you can certainly physically crank up the regulator past...

You can, I'll try to be helpful when and where I am able to.

The biggest reason is there is just enough clearance to access the hammer adjustment with a properly sized screwdriver in the current design to be able to adjust the hammer spring tension with no disassembly required. A longer cover would have required minor disassembly to adjust the hammer...

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...

Thanks! The Daisy 880, Barra 900, and Crosman 1377 all fight for being my favorite in my personal life. That said, I shoot PCPs more often due to work.

Looking forward to participating!
