Been doing some research and looking around to see what people have experienced and tested with the Maple Leaf Crazy Jet barrels, and from what I've seen they seem to be a good amount more consistent in accuracy than even the top of the line barrels such as Action Army and PDI.
(Link to the page with 1tonne's testing with the Maple Leaf Crazy Jet barrel: HERE)

Why don't I see more people using these barrels?
I could be wrong, but it seems like almost nobody uses them.

Also, I believe I read somewhere somebody did some testing with one in a SR25 and had good results. According to the retailers I see selling these barrels, they use their own proprietary bucking and should be able to work in an AEG. Can anyone confirm this?

If these barrels really are as good as it seems, I'd plan on putting one in my SR25 build I'm working on, along with a MAXX hop up unit. I plan on shooting right around 500 FPS and probably .4 gram bbs in a 16 inch/410mm barrel(410mm should be "better" than 455mm correct?) with this setup and using the stock concave Rhop nub that comes with the MAXX hop up unit. I'm not sure if the MAXX hop up unit would work with the slightly different bucking and barrel design, so if anyone has any thoughts or experience with that, I'd appreciate any info on it.

Here are the links to the barrel, bucking, and hop unit I plan on using if they will work together in a SR25:
Maple Leaf Crazy Jet Barrel
Maple Leaf Hot Shot/Crazy Jet Bucking
Maxx Hop up Chamber

*EDIT* Posting this also reminded me of the time a few years ago where Miracle Barrels were super hyped and popular. They seem to have died really fast. Does anyone have any experience with them? I've also seen there is a Miracle Barrel V2, which has just slightly longer "ramps" I guess you would call them, in it. I heard a lot of hype about these in the past, but never really saw many real results or conclusions on them. If anyone has any info or experience on these Miracle Barrels, that would also be appreciated.

They work quite well. I have installed ML barrels and hot shot buckings in decent amount of different guns. LVOA polarstar, maxx hop, ML hot shot, ML nub, and CJ barrel. Echo1 CSR, ML combo. CYMA AK-74U, Lonex hop, ML combo. ICS CXP MARS, Maxx hop, ML combo, Titan fet. LCT AK-74M, lonex, ML combo, titan fet.

2 of those are my own personal guns. The rest are customers. (That i can remember) no one has complained and all of them love the range and accuracy.

I run a action army hop up chamber and maple leaf barrel hop up nub and hop up rubber compared to the other 5 barrels I have tried the crazy jet seems to be the best

I'm currently testing the ML CJ barrel on a VSR system and comparing it to a 6.01 steel barrel.

https://www.airsoftsniperforum.com/41-vsr-rifles/56905-favorite-concave-nub.html

Linked above is the nub testing I did and what you can expect to see for the ML CJ testing.

So far I've been underwhelmed by the ML CJ in the VSR (3-8" groups at 100ft, which is much worse than the 6.01). For my Mk23 it works great, but the Mk23 is a highly overvolumed gun (due to it being gas powered) so the porting likely has some positive effect.

Last night I stripped the VSR down and reinstalled everything top down to ensure it wasn't an install issue with the ML CJ, as interestingly enough I have had positive results at 170ft+. But in the testing range of 100-150ft the groupings are all over the place.

Does that matter? In game probably not. As a 12inch grouping within 150ft is still a man sized target. But you and most others wouldn't be reading this forum if you weren't interested in how to squeeze every bit of performance out of your gun.

I'll continue testing when I get time and weather permits over the next week or so then post results.

For a plug and play system, there's nothing worng with Maple Leaf. When I was in revisions Ver. 2.0 to 4.0 of my L96, I used ML stuff...now? We're way beyond that...hahahaha

I've had good success with the crazyjet/hot shot setup, as well as hot shot/[other open window barrel here]. My main beef with it is that it's often not a straight drop in. Depending on hop unit, the lips tend to be loose and don't really hold a BB well which means you have to teftlon tape the lips to build them up a tiny bit. After that though, it's off to the races.

Like what the others said though, the crazy jet seems to do best when it's in an overvolumed gun. It's currently my go to for my gas blowback rifles. I have one in a WE L85, and the proprietary version for the KWA MP7. Both perform excellent and I do not see myself moving away from that setup

I stuffed my Maple Leaf (Broke my silencer off and bent it). So I have gone back to the Action Army barrel and it is working a treat.
To be honest, I like both barrels and don't really have a preference of one over the other.
Testing can be subjective to a lot of different things. Since the original test that is in the link in the first post, I have done other tests and both barrels preformed similar.

I'll be using a bore up cylinder setup with the extended cylinder in my SR25, and probably either a 455 or 410mm barrel(Not 100% sure yet which length. I plan on using .40-.45 bbs and around 450-500 FPS with SR25 bore up cylinder if anyone has any recommendations). This setup should get me a cylinder to barrel ratio of about 2.5. Would this be enough over volume to warrant using a CJ barrel? Or is that really only the case for massively over volumed guns like GBB pistols and some rifles? Or should I just stick with a AA 6.01?

Either length would be fine. I would most likely use the 455mm since you have the bigger volume.

I have almost same setup you mentioned (A&K SR25 with 2.5 cyl, sp150, RA cnc gearbox, maxx hopup chamber and MLCJ 180, 290 and 410 lengths - am using .45g bls bbs and Hotshot 60dgree bucking).
When it comes to efficiency:
MLCJ 180mm

0.2g - 385 fps - 1.38 J
0.45g - 315 fps - 2.07 J

MLCJ 290mm

0.2g - 491 fps - 2.24 J
0.45g - 356 fps - 2.65 J

MLCJ 410mm

0.2g - 545 fps - 2.76 J
0.45g - 351 fps - 2.58 J

So you can clearly see the efficiency advantage of 290mm barrel here. Nice JC is present as well.

Second aspect is consistency. I will compare those 3 barrels and one tnt S+ 420mm when the weather clears somehow here.
One thing I can mention here that tnt barrel is very promising.

Hi Nilye

As seen in your results by your short barrel had the most JC, the medium length barrel gave a pretty medium type setup while the longer barrel would be suited to a lighter bb (probably about 0.36-0.4gm).
I guess the barrel decision depends on the way people chrono the rifles.

I could be wrong, but it seems like almost nobody uses them.

My personal perception is that they are the most popular barrels for sniper rifles an GBBs (both pistols and rifles) nowadays, just like AAs were a couple years ago.

Maybe yours differs 'cause you're more of an AEG guy? Crazy Jet barrels in AEGs require using the hybrid / hot shot buckings, which is something that turns many people away from it. Throwing GBB barrels in an AEG chamber with some bucking that's neither is an idea hard to sell.

I don't build nearly as much AEGs as I do GBBRs and sniper rifles, but I've had success on some builds using the CJ + hot shot approach. Hot shot buckings are quite loose in most chambers, so that's something to be aware of.

Seconding the loose fit. A teflon tape spacer in front of the bucking and a few wraps of teflon over the bucking are 100% required for the Hot Shot in an AEG hop up chamber.

With that mod done, though, I have yet to see an AEG outperform this combination. It is on par with every R-hop installation I have seen as far as shooting 0.25-0.40 plastic goes.

My vsr is very accurate with the maple leaf hop arm autobot 50 and the crazy jet 410mm in the stock hop chamber. I am using longbow .45's with tight groupings at long ranges.

Since we are talking about the CJ barrel, lemme ask a few questions out of both curiosity and needs:

1. Would you guys recommend replacing an AEG barrel and bucking from a WELL MB01 in favour of a CJ+Hot shot rubber?

The current barrel used in my MB01 (2nd handed) is of unknown origin, performance is pretty decent but I am unsure so I'm thinking of a replacement.

2. Similarly, would you recommend using a similar setup for a CYMA SVD (aeg)? I'm aware that the CYMA SVD clone doesn't have the same capacity as the RS's original version, but it's already dangerously close to my limit so it might be a good idea to replace it with a shorter CJ barrel instead of the stock one it's using, knowing that it negatively affects FPS.

If they're compatible, then definitely. Hop up bucking alone is one of the most important parts of accuracy. Stock barrels, particularly Chinese guns, usually are okay at best.

I just installed a 70 degree autobot and 510mm CJ in my CA M24 LTR and it made a world of difference. Way more range and consistency.

1. Yes

2. In my Echo1 CSR, (same gun as the cyma) I have installed that combo. Works great.

Interesting!

Recently I found a hop up chamber made by T-N.T studio which is for the WELL Aps2 L96 family. It claims that it runs on GBB rubbers (aka maple leaf rubbers are good), so if i am using this instead of the planned Action Army it will remove the need of the Hot Shot rubber. However, my local tech suggests that while it gives very good range the accuracy is lackluster.

Should I go for this chamber, or should I go for the AA? The pricing is not too far off so budget wise it's the same.

Now you have asked a hard question. Who has used an AA Chamber and a TNT chamber. I have not but I can say that I have an amazing air seal using the AA chamber and an AEG bucking.
