Hello. I haven't touched Daystate, I can only say that it looks great. However, I can tell you a lot about Fx and AGN. AGN literally shoot straight out of the box, however it depends on what settings it came out of production in and for which country with the relevant restrictions. You have to consider what you will be shooting (cup or slug) and possibly determine the weight of the ammunition for the corresponding good grouping velocities. In Bulgaria, the preferred rifle is the Vulkan 3 long, regardless of caliber 22, 25 and 30. We shoot slugs en masse, in caliber 22 to 40 grains. This rifle is designed for slugs, the regulator is usually left at around 170 bars and shoots 37-40 grain slugs at almost 975 -1000 fps. The grouping is great, more noticeable at distances of 200 + meters. The O-rings are very few as a consumable, they rarely leak air. Due to the single-point attachment of the stock to the base, it is prone to wobble, a very unpleasant feeling, also the reloading is relatively loose and with gaps, it is irritating for me. But, apart from that, the work of the polygonal barrel, regulator and valve, they are simply impeccable. As for the Fx, they are simply refined in detail. Yes, sometimes it is difficult to quickly adjust it to shoot well with the factory settings. You have to touch the regulators, micro and macro settings, the barrel has to stabilize well when shooting with heavy slugs, but still everything is achievable. Owners or candidates for these Fx rifles need to be a little more technically literate and deal with more frequent maintenance and adjustments, it is not an option for them to send the rifle to a gunsmith every time they want to change the setting to shoot a different slug, for example. They need a set of tools, knowledge and persistence for support. Let's not forget the unique ability to change calibers with Fx, this is a very big + for them. I have a Maverick, tested in 22 and 30 caliber with a heavy liner, it shoots very well. And I also bought him an Alpha Precision in 25 cal. He shoots a laser with it. It's all a matter of good adjustment, nothing else matters!!! This is how we have fun in Bulgaria, see the pictures below!!!
