- To set the reg, you really need a good digital manometer as none of the small gauges are very accurate. According to everything I have heard, the crown factory setting is at 125 bar, everyone has a 1:30 twist rate barrel, and that configuration shoots best with the 25.4g jsb at around 890 fps.Remember when you change the regulator, take the tank off and fire the gun empty. That is the instructions from all sources and its been okay for me so far.
…same as above when reducing regulator pressure.If you are new to these types of guns, leave the regulator alone until you get a little more confortable with the other adjustments.The 1-2-3 know is the aperture, and the hammer spring adjustment is toward the back. There is also an allen screw on the hammer spring that you can increase and decrease the power of the rifle. you will need a very small allen and it is located on the end of the hammer spring in front of the knob.I’ve got my crown in and I’m working the bugs out of mine as well.I have an impact and a boss and am used to 6-10 fps differentials in a 20 shot string. I’m getting around at best 16 and as much as 24 fps differential between highest and lowest velocities per 20 shot string from a 250 bar fill.Still working on a good answer to that one…To set the reg, you really need a good digital manometer as none of the small gauges are very accurate.

But, it’s best to call AoA for the best answer at this point.

TomThat is how I adjusted my reg, unscrew bottle from gun and dry fire twice and it’s empty. Half turn in on reg then back on with bottle. Dry fire again and watch it stablize. In is pressure down and out is up. Trust gauge and shoot the gun. You can change gauge when another comes in. I bet gun is at 170. If worried swap them and verify.That is how I adjusted my reg, unscrew bottle from gun and dry fire twice and it's empty. Half turn in on reg then back on with bottle.

Do you think the FX gauges that have been consistently inaccurate are at least consistent enough to use to adjust
BACK to the original setting? Right now on my Impact I have recorded the wrench flats moved from original position when adjusted. sylvanGood info monkyshine Plan on adjusting my reg this afternoon.

My number on reg for me is 138 bar. Maybe it’s off some but that is my reference number. I zeroed gun in rain here but that is it for me checking real accuracy today.My Crown gauge is close to my two glycerin filled service gauges on my 6k nitrogen bottle and my great white as for reg gauge it's my reference to adjust even if it is off some high or low.

I’m fighting vertical groups with Extreme spread at 21 and SD at 5. Filled to 240, Reg set at factory 125 bar, shooting 25.4 jsb at average velocity of 890. This is the way my gun came from the factory. My test sheet shows ES at 11 but I’ve not been able to duplicate that once.What are you guys seeing for for Extreme spread and Standard Deviation on your crowns?

I tightened the hammerspring up to get them moving at 830 fps, but as you can imagine, that make the vertical grouping worse at 100 yards. …bigger arc, exponentially bigger variance at distance. At 50 yards, the gun is a laser beam but EBR is not at 50 yards…Did you move the reg or just the hammer spring? out of the box, mine will only move the 34s at 790.
