Are you mildot ranging?

   Different manufacturers have different systems.
Some you need to degas/depressurize - let all the pressure out of the cylinder/bottle before you can make internal adjustments to the gun.
But others you can just unscrew the cylinder/bottle from the gun and they will seal and hold their pressure until you screw them back in again. All depends on the make and model.

	Your not helping me keep a springer shooter lol. Is degassing removing the bottle as well? If so wouldn't a tap on bottle and firing the loaded gas solve that?. Or is it that to adjust you need to get into the gun by removing stuff.

	FX have really pioneered that over the last few years. Barrel liners allowing you to change calibres, but because everything moves, tensioning the barrel became important. Ironically People are now machining std barrels to fit. The impact has three external adjustment points, going from major to minor. All adjustable without degassing the gun. 1. regulator 2. hammer tension (course and fine adjustments) 3. valve return adjustment I have retro fitted regulators to different pcp's, fx cyclone, AA S510, AA EV2, and if they need adjusting, the gun needs to be degassed, so unless you have a custom reg tester, you only know the pressure when you regass the gun. With the impact you can do everything right down to harmonic tuning with the valve adjuster externally.

	Really you have to degas some models! Never realised that. That would suck. Sounds totally impractical. So was that just the older models or is still something to still be aware of in the newer models. I vaguely rember seeing something about being able to tension barrel liners/sleeves as well? I tend to flick articals pcp as I don't own one. Is that correct as well. It makes scence that if you could you'd want a way to tune your barrel. Well something better than an o ring on the barrel anyway.

	Yea pcp's get talked about a lot, and the FX ones have so many add ons and tuning capabilities that get discussed. I've got an impact mk2, and I got it because I was fascinated with the impact when it first came out. The ability to tune it without opening it up appealed too. I had tuned other guns, but got sick of degassing, adjusting, testing etc. Springers are great though, and really are the backbone of airgunning I reckon.

	I should imagine the pcps are pretty addictive. I've always hoped there would be more tech talk about pcps on this site. With the amount of adjustment that can be done to them, sleeve liners, differnt pellets at differnt psi, differnt charging actions, scopes that would be awsome on pcp but to much for springers etc it would be great to read what ppl are up too

	I agree 😂 the price of those thermal scopes is crazy! Unfortunately it’s not mine, it belongs to my boss, he just lets me use it, lucky me 😉

	Try this for mdot ranging explanation https://www.targettamers.com/rifle-scopes/mil-dot-explained/ A search under "ranging using mildot" will bring up heaps of articals.and videos also moa as well. Your scope Manuel should tell you what your using if not try a.search using your the full name and Make of your scope with the word retical after it. Should bring up details I found two that had 50 in the name but wasn't sure what yours was. Also one discontinued one as well. There is a nice gun, scope, and torch and mount for the price of those scopes!
