As some of you already know FX USA is very hard to reach by phone and FX Sweden seldom responds to them or customers. For those of you that have a Wildcat MK11 and possibly any other FX gun you should know some of the parts are not up to par. I have a Wildcat MK11 in .25 cal. I've experienced inconsistent trigger pulls from day one, (October 2018 bought new), to extreme spreads with velocity. There are two problems besides the regulator, which went out after 300 rounds. There were extreme spreads of 30 to 90 fps consistently with it. The smaller of the problems is the L piece at the end of the trigger linkage is SOFT metal. The set screw that adjusts the weight of pull is harder than the L piece. As a result the set screw digs into the L piece creating uneven pulls. A bandaged fix is to cut the 'cupped' end of the set screw and round it off so that it is smooth instead of sharp. If your trigger is 1 lb or more you probably won't feel the inconsistency. Mine varied + or - 2oz. sometimes more, which is a lot when the pull is set at 8 oz. The bigger problem with this gun and possibly several other FX models is the hammer is also SOFT. My gun came poorly adjusted from the factory which didn't help matters. As a result the shoulder on the hammer got literally hammered. If you dry five these guns or shoot them with very low air, which is easy to do since the magazines don't have a stop after the last shot, the hammer can make contact with the cocking pin chewing up the shoulder on the hammer. Once a "high" spot is created , see first two pics, you will have very uneven shot strings because sometimes when the hammer is released the 'high' spot on the shoulder will rub on the way down to the air valve slowing it down causing a low velocity. Mine dropped shots 40 fps slower that the average for a given string. There is a harden pin in the cocking linkage that pulls the hammer to the full cock position then the sear holds it there until the trigger is pulled. When the shoulder is damaged the trigger pull as well as the velocity will be inconsistent. The trigger, because the sear is not in the same position on the hammer, because of the high and low spots. Because the hammer is soft just cocking the gun is damaging the shoulder of the hammer. See third pic 
75 shots. There isn't a fix from FX USA at this time. I got a new hammer from FX USA in May or June of this year and it was also "soft". The original hammer and the new one tested @20RC. The sear tested @50RC which is what all the trigger parts should be. I sent this info to FX USA back in June when they were still taking calls and they forwarded it to Sweden with no response. I sent it again to Sweden from my end at the beginning of July before they went on their summer break for three weeks with no response. It took two months to find out what kind of metal the hammer was made from. Possibly it could be hardened and therefore saved. I realize that most shooters aren't comfortable taking their guns apart in order to see what the problem might be. And after spending the kind of money they cost one shouldn't have to ! You should be able to shoot thousands of rounds without having any problems. There are other issues with this particular gun concerning accuracy with the smoothtwist X barrel. Some of these barrels are not what they're cracked up to be. Sometimes the standard ST barrel is just as good and sometimes better then the X barrel. I have both. Don't think that putting an X barrel in your gun is going to be better than the original. It may or may not be better. Anybody that is having any of the above problems can verify what I've said by removing the hammer and closely looking at the hammer shoulder. If it's not 100% clean, not indentations of any kind, then you're having a problem whether you know it or not and eventually it will get bad enough and show up like mine did. According to FX USA Sweden told them that the hammer "ring" was hardened---it's not. It looks like these hammers are supposed to be hardened --but never made it. FX quality control is not real good. I've had four FX guns and there has been problems with all of them. Some minor some not so minor. So if some of you folks have an FX gun that's "perfect" count your blessings. I sent Johan Axelsson a note last week, September 22, 2019, asking him when or if we are going to get some quality hammers---no response.
