Your Avenge X is using the same barrel as the Avenger. I don't know which slugs you tried, or at what speed, but I know that my brother set his reg to 2900psi and shoots the 29gr NSA @ 942fps and shoots 1.25" 100y groups. Yes, the pellets can shoot a little better in no wind, but do not hit has hard and drop a lot more. Throw in any wind and the slugs clean house. Just something to try if you didn't already, 10fps or .5gr difference in pellet weight can change everything.
This aftermarket design is unappealing not to mention the high cost in todays Euro currency rate converted to 747.68 USD??? I rather buy a Saber Tactical @ $300 than this Aeron which aesthetically doesn't measure up to the Saber Tactical. I have been thinking about getting the Saber Tac. but haven't pulled the trigger yet. And at $787 plus shipping and VAT for a Aeron, I could buy another collectable PCP for that amount. My needs doesn't warrant spending $$$ on a Aeron I think most would say it's ugly. Now my wants is another matter. (i.e FX) I keep a balanced perspective on this hobby.
I respect your opinion but I would much rather have a Aeron (which is why I have two of them) over a Saber Tactical any day as they are lighter and much better looking in my opinion but to each their own. Of course that was just an example and it's for a firearm and you are right that price is too high but they would not need the butt stock or the grip since they could supply that themselves to keep the price down. If MA could offer a metal chassis in the $300 range I think they would have some real interest.
.. With reg at 2100 I played with the hammer a lot, and was still getting better consistency at middle tank pressure. Getting the same now that I've got reg at 1900. Guess I'll go back to the hammer tomorrow and see what I get. No matter what I still just enjoy shooting almost every night. Love this hobby. What is happening is that your hammerspring is now facing less resistence and releasing more air and the the pellet goes faster. You can try several different solutions depending on the outcome you want. One is to turned down your hammer spring and shoot your current pellet slower so that when it comes off the reg the hammer strike will be less and it will not spike as much. Two, leave it as is and try some 34gr pellets, the extra weight changes where the "knee" is and you won't get the spike either. Three, turn down your reg a little and when you come off of it with your current pellet it won't spike as much either. Welcome to tuning. If you shoot full strings you will see the changes, just be sure to watch your pressure and write it down as you go to match where you are on the curve. Being regulated, this only gets interesting at the end, but it's good to know how many shots you're getting, and how many good shots are left off the reg.
. From 3500-2400 psi tank pressure. Increased hammer spring tension, with reg @ 1900.
