Hello everyone, I'm on a quest to figure out which bucking, (no r hop or any of that jazz) will provide the overall best performance. I'm running a vsr10 with an AA hopup and flamingo bucking with a stalker panthera nub currently. I'm seeing great results with range and lateral groupings but always searching for better performance. (Though idk if it gets any better) I've previously ran the autobot 70 with pretty great results but slightly less range than the flamingo but not much, maybe 5 yards. The Mr hop provided great range with so so lateral groupings so I scrapped that idea. I tried the diamond for a day and couldn't get a good air seal so I scrapped that (though it was very consistent which I liked). I've yet to try the decepticon because I've heard mixed opinions, but it's on my list to try out. I've heard good things about the xrange but I've yet to try it so it'll be on the list. I'll update this post as I try the the buckings I haven't tried yet. I hope this helps someone build a more accurate rifle. I've got alot of mods and other upgrades but I want this post be about bucking performance. Experiences and opinions are appreciated!
I'm running an action army 300mm 6.03

Xrange is also great. I run the predator in my SSG24. It's the Flamingo for me as long as you have a good seal with it, or Xrange. But the biggest improvement you will likely make is by fitting a TDC. I have a tridos one on my 24 and just picked up a VSR. Having some piston issues right now so I haven't tested it. But my friends SSG10 is brilliant.

I have the AA hopup unit so there's no need for a tdc. Once I set my hop after cleaning it never moves and is extremely consistent. And I can over hop .48s super easily

I can't stand the hop adjustment on the AA unit. It's stupid. It's got a good fine adjustment on it but I find I have to move mine slightly during the day to accommodate for temperature.

Maybe something was wrong with yours. I play in Wisconsin through all the seasons and it's wonderful.

I'm UK. Not wrong. Just a lot colder and more moisture

I'd say try the 2021 85* Autobot, Decepticon, and MR as I got a huge boost over a 60* older Autobot.

Also try making my nub.

Maple Leaf 2021 Autobot buckings are my new go to. Finally retired the OG Diamonds. As for the degree, just pick your favorite color! 😂

Try doing a TDC mod or getting a Tridos TDC kit!!

@Creeper93
my suggestions:
ML Autobot (old version)
ML Mr HOP (old version)
ML Autobot 2021
ML Decepticons 2021
X-Range
Flamingo (not tested, but I read very good comments about it)

Combine any of the above buckings with SiliconeSword's nub

Yes I ordered it months ago, it came and finally fitted it today. The messing on trying to adjust the hop before is actually insane.

Sorry for long time in between updates but I have some findings. Decepticon was ok but I believe the autobot may perform slightly better in terms of range and accuracy. Xrange was quite good and I could see no difference in accuracy compared to the autobot but possibly a few more yards of range but nothing to get excited about. For now I'm sticking with the autobot as it's been very consistent and seems to wear really well. If anyone has any other feedback or info to contribute, that would be appreciated!

With the Autobot and Decepticon I made that finding myself, with the Decepticon seeming droopier that the Autobot, even when hopped similarly. Physics wise this doesn't make sense, but I do in fact think that my best R-hops were better than a Maple Leaf AEG bucking, when using a flat hopped Maple Leaf bucking.

I've yet to try the X-range as I currently only have a pistol that takes VSR buckings, but it does sound like a solid choice if it fits your barrel and wears about as fast as a 2021.

TBH I'm scared to try rhop because I've been down the rabbit hole for so long searching for the best hopup rubber and if I start something it kind of becomes an obsession with perfection that I typically don't attain lol but in all seriousness, what advantages do you see with an rhop over a standard bucking?

 

[SiliconeSword]

I've made hundreds of R-hops, with only 3 being really good, so I wouldn't really recommend it after having spent a few hundred dollars on jigs, resins, glues, tubing, and vacuum gear.
I am in the process of figuring out exactly what makes a good R-hop
My best R-hop was a piece of McMaster Carr 9X6mm 70* clear blue silicone tubing, where at like 2J with .36g BBs I'd get like 100 rounds out of 100 on a truck wheel at 86 yards, which is pretty damn good. I've had two other experiences, one with another piece of that tubing, and one with cast 80* urethane. I'm still perfecting all this, so I don't have any solid info to give you.

The advantages of R-hop is usually longevity if you use one cut from tubing, and you will have better seal as you can use a harder bucking to house everything. You may also gain FPS, and you should be able to hop heavier BBs at lower power levels, but that isn't guaranteed. I have given R-hop a bit of a break as I am pleased with the 2021 Autobot 70* in my SSX23, and the SHP7 60* in my M4, but I will likely continue on my next two guns I have planned.

I just saw your comment, it actually gets way colder here than the UK and we have 100% humidity quite regularly. Maybe you had a bad batch or something

Do you want a few inches of the 6x8.5mm silicone tubing I had custom made for me for Rhops to try (I bought 100m of it...)? The few Phops (Tubing is purple, I'm Pretzel, they are nearly Perfect, and Rhop is HS5s name) I've done have come out REALLY good, with people saying they shoot lasers. You're fairly local iirc so it probably wouldnt be more than a few bucks to mail it up to ya.

Specs are:
Material: Silicone
Hardness: 70 Shore A
ID: 6mm (Tolerance +0.10mm/-0.00mm)
OD: 8.5mm (Tolerance +/-0.10mm)
Color: Purple

 

[SiliconeSword]

Hell yea, PM me and we can sort something out.

My main struggle with the 6X9 tubing was shaving down the .45mm after you have it cut, which is super hard to do.

There's a reason I ordered it custom spec from a factory in china a few years ago - could NOT be bothered with that bull anymore lol.

There is X range packing which I believe required bigger hop up window, but modify-tech post youtube video how to trim your inner barrel window. The advantage for this x range is very good airseal (tried with AA chamber) without any mod.

Maple leaf I prefer decepticon (as hard as you can get for your FPS), I have tried auto, and mr hop 2021 all silicone one. But required mod to get perfect air seal, I double the ring at entrance side and teflon tape mode at the other end side which create fps consistency as x-range (1-2 fps and on my way to make this better) without this mods i got drop on fps +/-30 compared to no mods. (my opinion decepticon > mr hop 2021 > autobot).

All the hop that I have tested by using TDC 2.0 full concave nub.

I think that the whole air seal thing with buckings is mentioned too much, as with VSR buckings it is a easy thing to fix. You of course want to establish if your bucking is a VSR or GBB, as I've found that many GBB buckings like some mystery red one and the purple Novritsch one have wide openings, likely to aid with nozzle movement and feeding. Once that is established, you simply add a layer of some sort of decent tape or glue to the outside above the entrance, or if your chamber allows it, add the tape or glue to the chamber. This will squish in the entrance of the bucking, reducing the diameter of the hole and improving seal. For the Maple Leaf buckings you can use small strips of paper beneath the clip thing to achieve the same result.

I do give Modify credit for the entrance of the X-range though, as it is reminiscent of a cup seal used on certain hydraulic and pneumatic equipment, as they tend to flare under pressure, increasing how "hard" they seal. Not sure how much this matters over just having a correctly sized hole, but I don't think it could hurt anything really.
