VFC HK416 GBB Precision Hop Up Adjustment Arm Precision CNC Aluminum Long Range
VFC HK416 GBB Precision Hop Up Adjustment Arm Precision CNC Aluminum Long Range
The original VFC hop up arm tends to lack performance, especially when using big contact surface bucking’s.
This Product combined with the right bucking will increase the hop effect applied to the BB due to the spacers increased contact surface to the bucking, which results in better lifting performance especially when using heavy BBs (>0.4g).
We recommend the usage of bucking’s like the Begadi VSR5/7, Flamingo VSR, Modify X-Range, Maple Leaf MR or TNT TR-Hop.
Includes 1x nylon made curved spacer.
Compatible with VFC HK416/M27 IAR series, excluding V1 (hex-key adjustment)
Material: 7075 aluminum
Production method: CNC
Surface treatment: Oxidized
Model: BB0002

FAQs
Quality Standard
In the airsoft world, absolute perfection is neither possible nor practical.
While we constantly work on optimizing the processes, it's still very difficult to achieve perfect results with limited manpower.
Minor tolerances, marks, or finish variations are natural in precision mechanics and never compromise performance or quality.
Support
We take every piece of feedback seriously – but only if it actually reaches us.
Customers who contact us directly will always receive full support: replacement, additional shipment, or refund, handled promptly and without complications.
What we cannot do is monitor complaints posted in Discord servers, forums, or YouTube comments. In those places we see no order number, no details, and therefore we cannot provide a real solution.
Shipping
We aim to ensure fast and reliable delivery to all our customers, whether you’re in the EU or elsewhere in the world.
Shipping is either from our Latvian or Asian warehouse, according to the inventory availability
We will always pick the best lane for your country/area. The average delivery time to EU and UK is 5-10 days, to USA and Canada is 10-14 days, South Korea and Japan 5-7 days
Return & Cancellation
- Orders not yet dispatched can be canceled free of charge.
- EU customers are eligible to initiate return process within 14 days upon the delivery of the parcel
- Returned items must be in resealable condition, otherwise we have the right to refuse the return or reduce the refund amount
- If the return is not caused by our own mistakes, customers are always to bear the return cost
Upon installation and experimentation with a melange of various buckings (MR maple leaf, 4uad gbb bucking, stock vfc bucking, unicorn 70 degree comp bucking, and maple leaf 70 degree super bucking) as well as the included spacer, and other nubs like the maple leaf omega nub, the product just didn’t seem to work with the stock vfc 416 v3 hop up unit. It would either under hop, over hop, or produce serious feeding issues altogether in my 416a5 replica with both the stock and unicorn 6.03 tight bore inner barrel. I could never quite get it to a level of accuracy that’s better than that produced by the stock hop-up arm. The included hop up arm pivot pin also was much too long to fit the corresponding pin hole in the hop up chamber. I’m not quite sure if I received a lemon, but I can’t quite say I’m too pleased. I already achieved better results with just the 4uad bucking alone and the stock hop arm. Was looking to tighten my groupings with this, and just enhance consistency overall, but it seems it wasn’t quite the complementary piece I was looking for.
Nice! Dropped right in. Nice and tight in my hop unit. Bucking patch is nice and centered and even when hop is applied. Works well.
CLUCH
Hello, I'm an airsoft player in Korea.
I haven't purchased many of your products, but I've been using them well.
So, when I buy your products in the Korean airsoft community where I'm active, I occasionally write reviews.
I'm contacting you because I have some concerns.
( VFC MP7 M-lok HandGuard Review )
https://arca.live/b/airsoft2077/137092519?target=all&keyword=%ED%81%B4%EB%9F%AC%EC%B9%98&category=%EB%A6%AC%EB%B7%B0%26%EC%A0%95%EB%B3%B4&p=1
( VFC HK416 A5 Steel Barrel Rrview )
https://arca.live/b/airsoft2077/137310250?target=all&keyword=%ED%81%B4%EB%9F%AC%EC%B9%98&category=%EB%A6%AC%EB%B7%B0%26%EC%A0%95%EB%B3%B4&p=1
First, the MP7 option was purchased with a steel bolt carrier and an M-lok handguard.
The bolt carrier wasn't your fault.
It was due to the VFC's original design that the nozzle spring was stuck.
In Korea, we use a CNC machine to machine the rear of your steel bolt carrier and install the VFC AR nozzle spring.
This is a review of another user's creation, made by cutting off the back of your bolt carrier.
I'm using it like that too.
https://arca.live/b/airsoft2077/123464315?category=%EB%A6%AC%EB%B7%B0%26%EC%A0%95%EB%B3%B4&target=all&keyword=%ED%81%B4%EB%9F%AC%EC%B9%98+%EC%8A%A4%ED%8B%B8&p=1
This method works fine.
However, the plastic nozzle guides you provide are easily damaged.
We need to machine and install a metal MP7 nozzle guide from a brand called TagArt to fit your bolt carrier.
The link below is the product page for the TagArt mp7 metal nozzle guide I mentioned.

Second, your MP7 M-lok handguard
is really well-made and reasonably priced, which is nice.
The 3, 6, and 9 o'clock positions are fine,
but the M-lok screws on the other positions are too close to the MP7 body inside the handguard, making it difficult to secure them.
So, I think it would have been better if the design had been designed with a bit more clearance.
I'm very satisfied with everything else,
but I think your original design handguard isn't popular, perhaps because most Korean users value historical accuracy.
Thirdly, the VFC HK416 A5 one-piece steel outer barrel you made.
There aren't many third-party options for the VFC HK416A5, so this one is in high demand.
I really like the integrated chamber design.
The price is also very reasonable considering the integrated chamber design.
However, this product has a major drawback:
When fully installed, the steel barrel wobbles slightly.
So I'm using a device that I've made by cutting a piece of acetal material and inserting it between the barrel nut and the barrel.
The link below is a review of the results of my work.

I'd really appreciate it if you could fix the few things I mentioned.
If I had the money, I'd buy all your products and review them, but unfortunately, I can't.
Your brand seems to be less accessible in Korea because there aren't any stores that import and sell it, so not many users seem to use it.
I know of a Korean airsoft shop.
If you're interested, I can introduce it to you.
Even if that's not the case, I'd love to see your products more easily available in Korea.
Thank you for the great products.
Fit perfectly into my 416. Tested with 0.32 @ 360 FPS, standard barrel. Can't say if there is a huge difference, although I would try heavy BBS, 0.40 or something similar
The hop up nub that came with the hop up arm was too wide. I had to file it down to make it fit in the hopper chamber. Would’ve been nice if it already fit.
