The KWA 2GX Hop Up Bucking is the new standard equipment hop up bucking for KWA AEGs. This bucking provides two areas of contact for the BB for a more balanced backward spin. The effect this bucking has on the BB is similar to a baseball pitcher's four seam fastball, straight backwards spin for a stable flight.

This is an amazing bucking before it wears out, which it does quickly. It lasted me about 6 months of action (I usually play competitively twice a month). This is the best bucking on the market, only problem is its expensive and wears out in around 6 months. What happens is because the 2gx has 2 nubs in the bucking that press down on the bb, eventually the 2 nubs split outward and therefore don't give u any hop up because the bb is shooting right in between them. If you're willing to pay $14 every 6 months then go for it.
Best bucking on the market before it wears out (6 months for me).
Will increase your range and accuracy drastically. Yes, drastically
Wears out quickly (Should be within 6 months. Give or take a month or two).
You need to get the KWA hop up unit for optimal performance from this bucking.

This bucking is probably the most underrated bucking in the airsoft world, and if you EVER got a defective one, you have every right to be angry. This thing is honestly a Systema killer. I first found this on my old KWA G36c 2GX. At first, when I looked at the inside, i thought it was ripped up. Then i read about it and learned why it's designed that way. It's ingenious actually. The internal nub is separated into 4 fin-like structures. When over the barrel, 2 of these fins drop down into it. As the hop-up is activated the fins separate wider, and provide 2 points of contact on the BB at the 11 and 1 o'clock positions. As the BB slips under them, they allow it to spin near perfectly backward, which then allows the BB to catch the air more efficiently and thus allowing it to travel much straighter. This also increases range a bit, and GREATLY upgrades the accuracy (can easily fly through a chain of 2-inch gaps without hitting the edges). That boost won me a lot of matches where range was key, and nabbed me a ton of kills in some events. Even people using Polar Stars were being dropped just because this bucking helped my MP5 reach out there. Also, this may increase your FPS by about 10-20. As a side note, you will need to oil this up a little to get it into non-KWA hop ups. It'll be a slightly tight fit. Also, if your gun can utilize them, use .28g BB's with it. Your jaw will hit the floor so hard it'll throw off the earth's rotation lol. Happy hunting!
Ahem...."U Mad Systema?"
Best dang bucking i have ever had the pleasure to use.
Will increase accuracy and range.
So worth the 14 bones.
MIGHT be a tight fit on non KWA hop up units.

I dont see what everyones raving about, maybe i just got a lemon. i put this into my gun with a 6.01tbb, and the groupings were the same as the 6.01 with a G&P bucking, but there was one difference. about every ten ish rounds (wasnt perfect ten) there would be a couple flyers, which curved WAY off to the right. and yes, i broke in the bucking. i oiled it, and put about 900 rounds through it, cause i kept thinking it just needed broken in. i think what happened is there;s an uneven pressure between the two points in the unit. that could be the nub (doubt it) or that ones shorter than the other. i had high hopes, but it didnt really pay off. and btw, the G&P bucking never had a flyer, so its definately the bucking.
high quality rubber
at its best, had the same groupings as a G&P bucking (only $6)
