Maple Leaf Hop Unit & Inner Barrel Set - Fitting & Review for WE Glock 17

Maple Leaf Hop Unit & Inner Barrel Set - Fitting & Review for WE Gen 3 Glock 17 - How to improve the power (fps), grouping / consistency of your airsoft gas blowback pistol.
We show you what's included in the maple leaf hop unit and inner barrel set, how to assemble it and then how to install it in a WE Gen 3 Glock 17. Similar kits are available for the hi-capa. We then perform chronograph and grouping tests - putting it alongside the standard set up.
A simple upgrade that costs around £40 from most UK retailers.
The author of this video paid full price for the item and has no sponsorship/funds/investment in this product. We have no personal connection to milspec solutions - but would recommend them for sourcing parts for gas airsoft guns.

Brilliant video dude, i'm just about to install mine :-)

[@herminigildojakosalem8664]

I recommend the fully assembled Maple Leaf Inner Barrel/Hop unit/chamber set.

[@Airfonssoftballs]

Wow great video of your hands

[@ericyi5661]

Mine arrived today, then I happened to find this video. And at the end of video I happened to find that we purchased from the same website xD small world

[@BattleDogs]

Ironsight BABE!

[@bhante1345]

Watched a few videos on this system, had my doubts. Yours seem to justify the purchase, I think everyone else were just getting their presentation/assembly a little bit off.

[@felipeleon9273]

Can you please tell me how is the "i" key supposed to be installed in the hop up arm? I mean, how is the "curve" supposed to be facing to the bucking?

[@urukain35]

what about the range ?? did it make any difference in range ?? thnx for the video

[@tranquildoves]

Would this work on an umarex C02

[@AxShade94]

Hello, is the barrel as long the stock one ? Thanks for your video !

[@PantsuMann]

They are the same. Maple Leaf makes barrels for various Glock models, be sure to pick the right one for your gun. Hop Up chamber is the same.

[@charleyscurr8228]

Will this work inside a we eu17 glock?

[@Funkertruppen]

isnt adjustment wheel too hard because the rubber seal in the installing ping? or is just mine? maybe I am putting something wrong?

[@ankletoez]

I tightened mine too much, and it wouldn't allow the wheel to move. Just loosen it.

[@19jefferz93]

With this upgrade, what weight of BB would you reccomend? I was using .25s on the standard

[@sebastiancamillusnielsen228]

.25-.28

[@herminigildojakosalem8664]

What I needed to see was the assembly of the hop unit. I did not.

[@MysticExile111]

When I assembled the entire Hop-Up Unit, I'm running into an issue where after I put the screws back on, the Hop-Up Adjustment Wheel no longer turns due to it being too tight. Is this the result of over-tightening the screws, or could the hop-up arm being assembled improperly? Thanks!

[@adamkierzkowski1992]

Had similar problem. That black rubber ring needs to be below the actual wheel rather than on top of it, fixed it for me.

[@NoobehPvP]

@@adamkierzkowski1992 Hi can you be a little more specific, am having the same troubles.

[@adamkierzkowski1992]

@@NoobehPvP when assembling the Maple Leaf hopup, have a closer look at how stock hopup looks like. There is a little rubber O ring which needs to be placed under the adjustment wheel, that would be right part of the hopup chamber. But it is fact, that Maple Leaf wheel sits much tighter than any stock wheel. You can apply a drop of silicone oil to the ring and wheel for slightly better movement, however mind that it will also be easier for it to change position while shooting.

[@joecachia2]

Pity these Maple Leaf units cost half what the pistol costs. One thing I've learnt in any hobby (especially airsoft ) is that modding parts are overpriced like crazy. It's just another racket.

[@thatanimator2724]

ok

[@khris7963]

works with WE g18c yes? no?

[@matthiasroca2666]

it does

[@Underfaith]

I have an umarex glock 17 gen 4. Will this assembly fit in it?

[@superhans2435]

should work fine in TM/WE and VFC aswell

[@BembelinCz]

Isn't Umarex glock good enough as it is? Just upgrade the bucking.

[@Kulunek]

What is lenght of inner barell G17 ?

[@RaiZgr]

97mm

[@sabaradrawer]

I can't find it in any online store in or near my country :C

[@Funkertruppen]

they just have some restock problems cause of covid and air transport stops

[@p00nuk]

Hi there, Great Video, it was good to see how the I key fits. This is installed on my WE G17 and have noticed that even after adjusting the hop, it’s as if there isn’t enough adjustment to allow a straight trajectory. The BB’s still curve downwards at the end of travel. If you know what I mean. Anyone else had these issues and how to rectify? Thanks.

[@gorompulant]

p00nuk gravity?

[@p00nuk]

ZestyLemonGamer , it’s as if the hop makes no difference to the standard. You would think I’d get a slight over hop but it’s not the case

[@Anon18259]

I have the exact same issue. Have you found a solution at all?

[@Frambhueee]

I don't think it worth the money, it gives me more issues than solutions

[@Gattobuono]

This is a common problem on this type of hop up. The easiest fix, which works very well on the standard WE hop up, is to glue a small rectangle cut from an old aeg bucking (or similar material) over the two little prongs on the lever where it makes contact with the bucking. This will give you plenty of nice consistent hop, and it also negates the use of that fiddly little I hop thingamajig! Saving: €40!! :-)

[@realback686]

Does it fit for elite force g18?

[@ankletoez]

Yes I just did it

[@MysticExile111]

Was any lubrication necessary on the outside / inside of the Maple Leaf hop-up unit, or did you just drop it in and leave it without any lubrication afterward?

[@tengkusafwan8498]

i reckon no lubrication is needed for hopup chamber part, well at least that's what i did with mine.

[@fns58]

Never lubricate a hop up mate

[@teamironfoot7063]

Didnt put any lubrication on it.. it seems to work well without it 👍🏻

[@jingyang715]

does it work with WE g23？？？

[@Funkertruppen]

yes is tokyo marui,we,kj and some brands compatible too
