Does anyone know why my FX M4 . 22 shoots the first 3 or 4 low-power shots, for example, at 880 fps, and then evens out at 920 fps? I use 18.13 grain JSB. Thanks for your answers.

Hi All,

Bought this a few months back and picked up a synthetic stock version which serves the outdoor conditions up here much better.

Has a new Huma reg, brass hammer spring lock (to keep hammer spring adjustment in place), carbon fiber bottle, 2 magazines and single shot tray. Laminate stock is in good shape and is the ambidextrous type so is good for lefties or right hand shooters.

Current tune is the MK2 at 850 and are amazingly accurate, also loves the Hades at 900.

A very solid Royale 500!

Trade for other PCP airguns in .22 or .25 will add cash on my end if need be. If you wish to purchase instead of trade shoot me a message.

Scope, rings, bipod, bottle clamp not included.

Buyer disappeared so relisting….

This is one I REALLY wish had a traditional stock….This gun with the Sub MOA barrel is insanely accurate with 44.75 and 50.15 as well as the AEA and JTS variants. Being a big, tall guy the semi-bullpup just doesn’t fit me very well.

I am the original owner. Comes with the AoA power tune as well as 700cc 300 bar bottle, one magazine.

Has maybe 50 shots through it in total.

Note-Atlas bipod, scope, rings, 0dB not included….

Thinking 1650 and we can split the shipping.

Does anyone have a Raw barrel lying around they could accurately measure for being able to make a drop in replacement? Trying to not have to buy one to make one.

What's the farthest target you have hit with an air rifle?

First, let me say that I love the quality and uniformity of the AEA/JTS pellets - they beat the pants off JSB/FX/AA comparable pellets. I think that the AEA/JTS are awesome for .22 and larger for benchrest (other than the nipple on the front). But, I have been struggling lately with barrel fouling/leading with using the AEA/JTS pellets. I have tried cleaning the barrel more frequently, as well as using Slick 50 lube on them. Some barrels can go 75 to 100 rounds, but others may only go 20 to 30 rounds before visible inaccuracies show up. That is, I can get 1-hole groups for 20-30/75-100 rounds, then flyers show up. This appears to be a repeatable pattern. I am attributing the flyers to fouling, as I could see lead buildup on the front of a pellet when I pushed it through the barrel after a shooing session.

Based on their hardness and anecdotal accounts, the AEA/JTS pellets are reported to have higher tin content in them. So, I am wondering if the tin, being a lower melting point, increases the fouling issue. That is, since tin melts lower, you get bullet dust/swarf building up, then sticking and melting together into the problematic areas. I recall one shooter at the PAC pulling a ribbon of fouling out after shooting JTS pellets for a long period without cleaning. Is it possible that colder outside temperatures where I shoot, are exacerbating the issue?

Is there any way to combat this issue? I have tried HBN, but not much success. I tried sizing the 21 gr .22, which extended the cleaning period, but didn't eliminate it. I am currently using Slick 50, which seems to help, but fouling still a problem that would be an issue during a longer benchrest match. I have polished and waxed the bore with multiple chemicals, with limited to no success.

Any suggestions before I give up on this brand?

I’m routinely traveling between sea level and 8-9000’. Should I be concerned if I charge up a PCP rifle or pistol at sea level and then take it up to a higher altitude?

AOA was giving away a couple NOS unregulated Brocock XRs and a NOS unregulated Daystate Revere seriously cheap. I couldn’t resist the .25 Brocock. They have listed another in .22 but they are asking more money after the first 3 sold immediately. On purchasing it I figured there was plenty of room in the price to add a Huma or Lane regulator. After shooting it and noticing no real change in POI, I am wondering if I should leave it the way it is. I have regulated PCPs and I would have thought I was done with unregulated guns. Is there still a place for unregulated PCPs? The fill pressure is 200 bar yet it has the same 250 bar rated bottle as the regulated version so that may or may not be beneficial as you can only shoot to reg pressure vs shooting unregulated till the POI drops off the map.

Looking for some opinions if anyone has used this scope called the one by DNT 7-35x56 ffp just wanting to know what you think about it is it worth the money? Is there anything out there in this price range that you think it’s better and so on

FX Crown MKII with Nordic Wolf GRS stock. This rifle is set up with a 500mm .22 barrel. Asking $1500 TYD for rifle with, two FX magazines, and a hard case (scope, wheel and bipod not included). PayPal (FF or invoiced if you pay additional %) preferred.



I machined out a place for an inset Anshutz UIT rail which is screwed and epoxied in place (similar to the Dreamline GRS stock). Included is a 45mm long picatinny rail which slides in the UIT rail allowing me to use picatinny bipod attached to the stock rather than the bottle adapter.



The rifle has the FX Crown Power Upgrade kit (new spring carrier, 10 gram hammer weight, pin probe) installed, but I decided to put in a heavier Huma Brass hammer weight and keep the pellet probe. I will include the parts removed as well as the pin probe and 10 gr hammer weight.

As setup now I am shooting JSB/FX 18.1 gr pellets at 880fps with an SD of 2 and an ES of 9. I just tried the AEA 21.9gr Diabolo pellets at 820fps and am getting ES of 7 and SD of 1.5. Check out the AGN 30 Yd Challenge for an example of the accuracy at 30 and 40 yds. Last week scored a 200/200 with 15x’s on the 30yd Challenge with the 21.9’s (see Post #3018).

NSA used to be the best price for slugs, now they are just as much as ZAN and the rest. I nlw see why there are so many people leaving pcps to shoot powder again. The risimg cost of slugs is pushing people back to just pellets or just movimg back to shooting powder. What gives? I am curious what other's thoughts are on this trend. I will keep shooting my pcps but it will certainly make it harder to get newbies into the sport. Did lead go up? Jsb pellets are still the same cost.

Hello all,

I live in a rural-ish area and would like to hunt the woods not far from my house this coming September (small game, mostly squirrel and rabbit). There are neighbors in the vicinity, so an air rifle is a better option for me than a .22lr. I think I have narrowed my choice down to either the AGT Vixen or the BRK Ranger/Atomic. My priorities are a) the gun has to be well-built, b) the gun has to be relatively easy to work on (changing seals, mostly), and c) accurate out to 50 yards.

By this point, I've watched dozens of hours of reviews on YT, read about the two guns on all the forums, etc. YT reviews for both are overwhelmingly positive, but I've seen some negatives about the Ranger on various forums, mostly relating to BRK's QC.

So, which would y'all pick? I really appreciate the feedback.

I saw a post a while back about "are expensive airguns worth it?" and it got me thinking.

I've been kind of discouraged by the offers given by shops to trade airguns. I know in the powder burner world, the usual offer is 65-70% depending on popularity, but it seems in the airgun world it's far lower, in the 35-45% range. I'm talking about top shelf airguns, that cost $1200 and up.

Anyone else wonder about this discrepency in values? I mean maybe it's true, they're not worth it. I know it's a hobby and we're not here as consumers to make money, but it sure seems out of whack. The new Blackwolf is pushing a price most of us don't/won't want to pay.

The fwb 124 are all old guns now, the seals crumbled and need replacing. When in this process new piston seals, new breech seal , spring and spring guide etc.. Not unhappy with stock performance but while going through the installation would like to improve for best results. Reading here many have been down this road, looking for advice.

Greetings form Georgia. I'm new to the forum and new to the sport. I've owned a Gamo (I think a Raptor) for several years but bought it on a whim with very little information. Having gone down the rabbit hole now, I know that I really don't know much about anything. I mostly use my rifle for squirrel and rabbit hunting. The occasional groundhog. I'd like to buy a PCP and outfit it with a decent scope. I'd really like a Bluetooth scope, but that may be for another day given that I don't know much and I'm on a bit of a budget. I'd really like to spend less than $1,500 including a compressor, but I could justify (I can talk myself into anything) $2,000. Any recommendations? Just looking for a nice, accurate squirrel hunter.

I know on some other forums the noobs get razzed, so I'm prepared with armor and shield.

Thanks in advance for the replies.

Let me first set the table... I've been a long-time outdoorsman with a 23 yr military career behind me and have been a "powder gun" shooter for most of my life. In "powder guns," I can pull one out of the box, give them a good cleaning, set up the gun(s), site in, and then count on them to HIT what I am aiming at, with the FIRST shot...EVERY TIME. None of these guns are considered "high end." I have 4 Ruger 10/22 rifles in various configurations, none costing more than $500, and each will put 10 shots in a single ragged hole at 50 yards, with whatever ammo that's compatible. All of my center-fire rifles will do the same, but at 100yds+.

Due to health issues related to my military career, I am 100% disabled and can no longer hunt, but to still be able to "shoot", I turned to "Airguns.".... I started with a few different "Springers". And I still can't understand why those types of "airguns" are even made/sold... unless you just want to solve problems each time you shoot them.

After that, I dipped my toe into the .22 PCP gun ocean... The first was a Marauder, then a Gauntlet 2, then a Notos, a Niksan Ozark, and most recently a Barra 1100z Gen 2.. It took a lot of modification to the Marauder to get "relative accuracy" out of it. I could never get the Gauntlet 2 even close to being "accurate", no matter what I did to it, and thus I no longer even shoot that gun...... money wasted. The Niksan Ozark was an impulse buy and a total waste of money. (plus a very bad experience with the seller) The 1100z was returned under a warranty issue (a new one is currently on its way to me), which leaves the Notos...the least expensive of the lot, and is the ONLY gun out of them all that will consistently put 7 shots (mag capacity is 7) in a single ragged hole at 25yrds, with any pellet I feed it. If this is possible in a sub $275 gun, why is it not demanded/expected in EVERY PCP gun costing more than $1K?

Preferring traditional style guns, the FX DRS recently caught my eye, so I watched videos from Pyramid, and Gateway to Airguns. In the Pyramid video, the host was "wowed" with a 3/8" group off a benchrest. In the Gateway to airguns video, the host louded "accuracy" of the gun, but out of 4 groups....only one was a single "ragged hole" off sandbags. Other groups were "scattered", which makes me question consistency. After checking, I was very disappointed to find that the DRS, in the least expensive version, is a $1k gun.

So, having said all of that, I've read time and again... You have to pay for accuracy in PCP guns. My question is...just how much must an individual pay for a traditional style PCP to get CONSISTENT ACCURACY OUT OF THE BOX without having to test endless pellets and/or make modifications to the gun?? OR does anything like that even exist in the PCP world??

What do I want? As described in the first paragraph, a gun that once "set up" will give me confidence in its accuracy each and every time it's shot... but moreso a gun that I can trust to be accurate on the fist shot... because in most pest/varmint/small game hunting situations, that first shot is the only one I will get.
So far, the Notos is the only PCP I've shot that gives me relative confidence in first shot accuracy, and it's the least money out of all the PCPs I own. However, its downfall is power. I've literally watched pellets bounce off squirrels when the shots were beyond about 35 yards.

The STUD Chain Drive "Slug Only" Mag for the FX DRS is almost here! Another first from STUD, built to give PRS .22 shooters the advantage they’ve been waiting for!

The mag will be available in .22 and ,25 calibers.

Stay tuned—this is a game-changer. #STUDLoadingSolutions #FXDRS #PRS22 #SlugOnly #NextLevelPerformance

Is it legal to ship Airguns to Chicago

Hi guys - I just got done with opening up all the ports, added Huben Dream valve with bottle, 500mm barrel kit from C-88, regulator set around 2400-2500. Shooting 13.43 pellets, getting avg of 1014 fps and 31 fpe with small hammer spring adjustments. Would like to clean up the hammer itself as it occasionally gets a little rough when cocking but I live with that.

Only thing I haven’t done is open up the 3 ports on the barrel, but don’t think that’s necessary at this point? Maybe I’ll try that next, but wanted to see if there anything else I’m missing or anything still recommended to max this thing out (unless it’s already there).

Also, has anyone done a threaded barrel and/or shroud mod somehow? Would love to just screw barrel back in as opposed to this grub screw setup, but maybe it’s designed that way for a reason not sure.

This group has been awesome in giving advice and feedback while going down this very deep rabbit hole!

Still need to refine the setup a bit and reposition the table. But was able to take these two tonight. The rats knew I was there because there was an unexpected by me, backlighting situation. Anyway stayed only an hour, as it was a long workday and I got cold. And like I mention I need to refind the setup. These two were taken at 15 yards, as you can see and hear. The Atomic with the TP on low and the CPHPs simply wreck them at those distance… Both rats were lobotomized…

So we know that the speed of sound is the upper speed limit of any gas powered gun, but also that the speed of sound will vary depending on the gas being used, the temperature and it's pressure. Under normal conditions however the speed of sound in air is about 1125 fps.

Just sticking with air here, it seems that spring piston rifles can significantly exceed 1125 fps mostly by superheating the air as the piston compresses it. The fastest velocities I have seen claim to be in excess of 1600 fps.

PCP rifles seem to be able to also exceed 1125 fps, but not to the same extent and I haven't found many reputable sources claiming velocities any higher than 1300 fps, This is where things get kind of interesting. AI and most of the physics tutorials regarding the speed of sound will claim that pressure does not play a significant role in the SOS, but it quickly becomes obvious that this is because they are only considering normal atmospheric pressures. When you try and get estimates of the speed of sound at the kinds of pressures we're dealing with there just doesn't seem to be much out there. I've looked at Bernoulis Equation, but trying to find things like the density of air at 5000 psi isn't exactly easy either.

I'm just wondering if any of the engineers or physicists out there have any ballpark ideas on the speed of sound at high pressures. Also, it would seem to me that with the way PCP's operate, the expanding air should be cooling as it expands which would in turn also lower the speed of sound.
