How to check upgrades

it looks a bit manky, but it is the inside of it that counts


What have they put on that?!

To be honest, that’s probably your issue, my brother sent his DMR into same shop as you Ash, and it came out with a split bucking covered in silicone oil....
Looks  to me like  it’s kinked at the bottom.

 
Yeh, if that oil has been sitting on the bucking for that long I'd just ditch it.

Also look over the barrel. Looks like it could be a PDI one given the location of the etching.
Yeah about a year I think.

 
if it is a year old then def change it, even if it wasn't covered in crap it'll be worn and tired.

Not like I ever shot much through it. Maybe 50bbs. I believe it was kinked and double feeding from the start when I picked it up from store. Need to find a new rubber in the next 48 hours though.

You may have to ring up that shop you hate almost as much as me and ask if they have any in stock...

I hate how they put prices on their website, then you go in and mysteriously all the price tags are more expensive. I think I’d probably rather just give the game a miss than go there, I wouldn’t enjoy it anyway knowing I’d been fleeced for a piece of rubber that they buggered in the first place.

Used to go to action hobbies in MK but apparently they moved. Then there’s FireSupport up towards Peterborough, but they don’t seem to stock maple hops which I’ve heard are the ones to go to.

 
Might be someone on the forums with a spare Mapleleaf bucking. Usually quite a few knocking about so...

I put a wanted post out :)  No responses yet though.

So I took the cylinder out and it was a blue Airsoft pro cylinder too. As for inside hop, the hop rubber had a ribbed exterior and inside was a W shaped bucking. Not sure if that’s stock or not.

As far as I can tell, inside I’ve found upgrades which are:

AirsoftPro Trigger V3

M150 Spring

AirsoftPro Zero Angle Piston

AirsoftPro Stainless Rounded Cylinder Head

AirsoftPro CNC Hop Arm

430mm PDI Inner Barrel with spacer

Does that sound about right? Anything else missing that you’d expect to be there?

Since I’m getting a new maple leaf bucking, do you think it’s worth getting an aftermarket hop chamber too?

Sounds good to me.

I would honestly not replace the hop chamber yet. Try the Maple Leaf rubber first with that hop unit, if it’s less than desired, then consider replacing it.

Still can’t figure out what exactly is causing the feed issues though.

 
Rule out the hop rubber first, maybe a bit of that grease was sticking in the bucking. Once you have rules one out, move on to the next. It can be many reasons, possibly the nozzle, location of hop unit, hot unit itself etc.

Can’t find any decepticon buckings in stock. Any other recommendations?

 
It’s about the shape of the mound inside the bucking. 

Decepticon are “arrow” shape^ like so, autobot are diamond shape <> like so, autobot have a larger surface area so give the BB more backspin = more range. The decepticon puts the backspin in a certain spot on the BB and therefore not the whole BB has this “interaction” and therefore less forces to move it from its intended target.

There is a video and a better description on the sniper forums about this.

This description is very vague so take it with a pinch of salt. If I was you, I’d look at the Autobot 60 or 70, 70 will last longer, but 60 is possibly better performance.

 
Marketing rubbish. The two go hand in hand. You get range and accuracy from consistency.

The only limiting factor might be the amount of hop a single bucking can apply given its mound shape, but I can't think of any VSR bucking that doesn't have enough material or suitable softness to lift even the heaviest BB. Remember range only comes from the backspin, and being able to get a consistent backspin means that one can more easily dial in a hop out to longer ranges. A 'better' bucking holds this consistency even with a heavier weight BB, and heavier BBs will always go further.

Basically, check the sniper forums. I believe the consensus is that the autobot is bettererer. 60 or 70 degree will work for most people. Performance will last until the bucking wears out - if the gun fails to hold hop then either the bucking is fecked or (more likely if it's just slowly getting worse) your hop arm is moving when it shouldn't be. At that point you'll want to look at a hop unit.

I'm reasonably convinced that the airsofting industry has just about peaked when it comes to VSR buckings. There're only so many ways that one can put backspin on a BB.

That’s two of us who think the same, can’t go far wrong with that Ash;)

Was looking at the 75, so probably too hard. Will give the Autobot 70 a shot.

The issue I have with the feeding at the moment is that with the hop disengaged, 2 BBs feed and one rolls out the end of the barrel if it's pointing at all downwards. Then as soon as the hop reached about 40% engagement, only 1 BB loads but wont fire and jams in the barrel.

Go one level softer than the recommended for the fps.
