Same here, I have 2 coming this week. If they work as advertised, I'm going to order one for my Crown.

Hi jasmlowe. Do you have a maverick sniper 30 cal you are trying to get mucho power from like me?

You can add belleville washers to the FX stack and get pretty high pressure on the amp reg.. I have my MKII impact at 212 at the moment. Btw, I wouldn't dry fire the maverick. I was getting ding marks on the hammer from doing that. I didn't like the huma because of the aluminum.

Just be careful when taking out the washers so the orientation would be the same. The tool helps a lot.

TwoLeo88, so your valve and hammer are working with over 170 bar (2nd reg)? I don't think I will be working at more than about 165 bar on the 2nd reg. But the maverick wants to have more than that on the 1st reg and that is where my current problem is -- hoping just switching to brass pistons willl solve that. Thanks for the info about hammer getting dinged up. I have heavy (13 gram) hammer and a spring washer behind it (which effectively adds a little weight), and a huma tuning spring -- so I think I have enough hammer smack to drive at 165 bar (maybe).

Me too. Unfortunately I think it might get a lot of use. I like shooting airguns, but honestly I hate working on them unless I'm going to get some big improvement as a reward.

I have 20+ years of working on airguns and guns. I really enjoy working on them. Not that I look for something to break, but I really like understanding how they work, and working a problem.

My maverick is the only pcp rifle I own and the thought of taking it all apart and reassembling it is way scary. I know it's gonna happen someday and after that I might be wondering what I was so afraid of. Sometimes I think I should just do that and get it over with so I do understand the parts.

I have a question on changing to the brass piston. Do I need to do both regs or just the first or second reg? Thanks

This was me with my Maverick Sniper. The first time I had to disassemble the gun I was concerned. After it was done I was surprised at how easy it was.
Earnest Rowe has some FX Master Class videos on disassembly and assembly that were very helpful.

Hi Chukar60. Thanks for the encouraging post. That definitely makes me feel better about the maverick and my not-so-great mechanical skills.

Hi DanH. I'm no expert, but I'd say it doesn't matter if you do one or the other or both.
In my case, I will change the plastic piston in both of my fx amp regs to the brass piston eventually, BUT I'm going to do the 1st reg 1st just to see if it holds at 190 bar and leave my 2nd reg bypassed by opening the reg set screw to flush with the reg housing. That way I can leave the gun sitting for a few days and just keep my eye on the 2nd reg air pressure gauge which will be showing the 1st reg air pressure. Depending on the result of that, I will know if I need to add belleville washers to the 1st reg in order to even get to 190 bar without problems. Once I have experience with the new piston in the 1st reg and know how it behaves and is sorted out, THEN I will change the 2nd reg piston to a brass piston.
In the end, I'm hoping to get my 1st reg to hold at 190 bar and my 2nd reg to hold at 165 bar. I'll be shooting nsa 54.5 grain slugs at about 965 fps with my maverick sniper 30 cal with the 1:18 twist rate barrel liner if all goes well.

Follow up. I ordered 2 of these. One for each of my Mavericks. It was so easy to install with the tool, I'm going to order 2 more. I think I may put one in. my Crown MKII as well. Here is a pic of what the old one looks like versus the new brass version. I spent $50 for the tool and $30 with shipping from FX for 2 of them.

We both bought the same 2 pistons and tool. I received them last week. I haven't installed them yet, but I intend to install the 1st reg piston ASAP. I haven't even removed the old regs yet. I think I'll make a pot of coffee and remove the 1st reg tonight just to see which bellville washers fx put on my maverick and measure the thickness of each of them. Then I'll think about how to proceed from there. I hope the 1st reg can hold at 190 bar without me having to order washers.
I've read in other threads that the brass pistons are "too long" or that they "stick out too far" or that "there are not enough threads". Did you notice anything like that on you mavericks? I guess I'll be answering that question for myself very soon.
I'm always happy to find more fx maverick owners (happy ones anyway). When I first got mine I was afraid the maverick was going to be just a flash-in-the-pan kind of rifle and become extinct before it even got off the ground. Seems to be more and more of them all the time now. There seems to be lot more 22 and 25 cal out there than 30 cal. I figure most guys don't need the power of the 30 and they get more shots per fill too, so that makes sense.

HI Guys
I recently installed brass piston in both the amp regs of my Maverick,
i am facing a leakage issue issue , there is a leakage of air from the vent hole in the plenum cylinder (opposite side of the 2nd regulator), and as soon as i put the bottle the air leakage starts from this hole . Any advice is welcome for a fix and which which of the O rings may have been busted, thanx

This is my brass piston experience so far. I installed a brass piston in my fx maverick 30 cal sniper 1st reg. With the delrin piston I was able to set the reg to 180 bar (probably more, but never tried going over 180). With the brass piston 172 bar is the limit before it starts bleeding air because the brass piston is longer than the delrin piston and the adjustment screw runs out of threads. Well, it's not actually out of threads (it didn't fly out of the regulator), but it's out of room internally for further adjustment. Now I need to buy bellville washers to add to my stack just to get the pressure setting I was getting before. I'm actually wanting to go to 190 bar. So my airgun is benched until I get more washers. I have 12 washers on there now (6 flying saucers). I thought that would be enough to get me to 190 bar. Oh well. It's not the first time waiting for parts and it won't be the last.
