"In my previous review of this product I rated it very low due to a poor performance. I now know that was a human error on my part. I had not realized that my hopup wheel was too loose and would spin when the BB hit the nub. This would cause a few shots where the hop up was good, then the hop up would be turned off completely. Then I would turn the wheel the whole way up. This would cause the wheel to become immobile to the force of the BB, but it would cause a huge overhop. Using my trusty Scientific Method I deduced this issue and experimented with the use of washers to tighten up the wheel. To my amazement adding a single tiny washer solved all of my issues. My gun now can reach out and crush someone when they think they are out of range. When I corrected my error this upgrade became a huge improvement to my stock, misfeeding, erreratic Matrix SR-25. I highly recommend that you buy this upgrade and I hope that my mistakes can help you out.
"I had high hopes for this bucking and nub after I lost my stock nub. When I installed this on my Matrix SR-25 along with a Madbull tightbore, I was having serious issues with underhop. I would increase the hop up at a regular pace when, suddenly, I was having serious overhop. The adjustment on this nub is so coarse at the higher levels that even the cycling of a gearbox and the slight movement of hopup wheel causes that the BB's to begin under and over hop erratically. I gave this a three because I am new to modifying my guns and it is completely possible that I made the mistake in this installation. If I do find that this was my own error, hopefully, I can correct this and I will promptly change my review. Until then though, very disappointed.
Gun: VFC Avalon Carbine
Ammo: EliteForce 0.32g
Spring: Stock, running around 420 fps on 0.20g
Hop-Up Chamber: Stock
My Avalon came with a Maple Leaf bucking as a stock bucking and the results have been more than acceptable, however, it started showing signs of inconsistent hop as i moved for bb weight heavier than 0.3g. Trajectory became too parabolic, there was a noticeable lack of hop.
As i increased hop pressure the bbs lifted and started rising over, having a weird path and groups became too wide for my taste. The Maple Leaf works very well but there is a weight limit. 0.32g is well beyond it.
Then i tried this Flat hop bucking:
The install was not so simple. The Hop-up arm on the Avalon has a clamp design and the Baton Nub is too shallow to get secured by it. On tech pages some people milled their Nubs so it woud fit, some others said a Namazu firefly was a better option.
I didn't do any of these options. As i instaled the bucking in the barrel, some silicon lubricant is necessary because the bucking is 2mm longer than the normal so be careful to not stretch it otherwise it will interfere on the clamp (some people cut it, i was careful and cutting was unnecessary).
After the bucking was in place i simply droped the nub inside the chamber gap, just dropping it over the bucking, totally loose over it. Instaled the chamber arm right over it, the arm clamp design secures it in place...
And to my surprise it works wonders. No issues at all and the consistency improved alot. With my red dot i can hit coke cans easily 30m away now. The bb path became alot flatter and groups thighter. My next upgrade will be using this bucking and nub for an R-rop.
I will buy more of these to improve my friend's guns as they noticed my gun was incedibly superior to theirs in precision. I barely use full auto, it became alot less necessary. i can land hits on oponents 30m away without showering bbs over them now.
If you can tech properly and can handle yourself, get these.
