Systema Hop Up Bucking for Airsoft AEG Rifles

21 Customer Reviews

"I only use this bucking in all my AEG's as an immediate upgrade. I've been doing so for over four years now, and have never had an issue with these buckings. Whether used as a normal bucking, a flat-hop, or an RHOP, this bucking has sealed the best. I've tried many buckings - this, to me, performed better than Prommy buckings. The BB contact nub inside the bucking is a bit larger than most other brand names. To weigh the Systema hop up rubber against stock G&G green buckings when properly tuned, I immediately gained an extra 30 feet (measured). I will only continue to use this bucking whenever possible, in AEG's, or bolt-actions (PDI hop chamber).

"Best bucking ive ever bought, i got this and an element hopup in my BBoys RAS2 and at 30 feet, its dead accurate, its only my CQB gun so im not worried about distance to much but i would highly recomend this to anyone

"Well systema buckings are pretty good due to the type of rubber used. It is one of the softest on the market. I use it in my 400/20rps builds because softer rubber gives more moldabilty and gives greater backspin on the bb. You will need to replace this before a harder one, however I check my guns after every game so it's not a big problem. OVERALL GOOD BUCKING

"To anybody looking to buy this bucking, buy it now! This thing didn't tear during installation despite twisting (I have no idea why people are complaining about tearing). When combined with the PCS spacer and 6.03 tightbore, this thing dramatically increased my accuracy. For $8, this is one of the best and cheapest upgrades you can do. And to the guy below me: They sent me the bucking pictured and it works great.

"Just a couple of days ago, i received this and a Madbull Python 509mm. I wanted to put both in my CYMA M14 because the accuracy was horrible. Upon attempting this, i realized that the notches are too far back for an M14 hopup unit... so, the barrel didn't work in the gun. BUT. I sliced off the rear end of this bucking to make it fit on my stock barrel. and guess what?? HOLY HECK. THIS THING WORKS WONDERS. it up-ed my accuracy by (i'll bet) 175%. i can hit stuff dead on with my scope at 5 times zoom right in the center. awesome cheap upgrade, and definitely one of the simpler ones to do.

"for 8 dolars it noticably increased the accuracy in my p90, need i say more.

"Yes, this bucking tears easily. NO it is not garbage. Get 2 or 3, or get a madbull shark if you want a little less performance. But if you care about accuracy AT ALL, the bucking should be the first thing you replace (save TM guns) so much so that it affects accuracy more to get an $8 systema bucking than a $160 PDI barrel or $270 PDI cylinder set. There is NO reason not to get 3, because if you are sticking with airsoft, even if you don't rip the first one, you will use them in all your guns.

"I use this with my 6.03 systema tbb in my jgsig552. It truley has amazing accuracy. With this combination it can compete with top of the line products out there. If your choosing a new bucking for your gun this is the one to get.

"Super great upgrade!!!! No sweat to install. Took less than 10 minutes with disassembly. This bucking, coupled with my SCS Spacer and G&G stock tightbore barrel give me ~3 inch grouping at ~75 feet. Best bucking for your money, no doubt.

Pros:
Easy self-installation (mine arrived within 12 hrs of a game)
Low price
Bumps up accuracy a lot

Cons:
Absolutely nothing!!!!

In conclusion, the best bucking for your money, sold by the best airsoft retailers. What more could you ask for?

"This systema hop up bucking is great! It worked perfectly in my CYMA cm.036 and my new jbu tightbore and matrix metal hop up unit. A hop up bucking is pretty simple, and it works great.

Pros:
Systema
Great Quality
Better air compression and accuracy with the new setup

Cons:
None

"This bucking is beasty for the Echo 1 SCAR that has hop-up problems.
It fixes the problem completely.
by James H. on 03/15/2009
"great bucking. i just installed it on my agm hk 416 and noticed a considerable increase in accuracy and range. i had to cut a little of the end to make it fit.
by Mathew D. on 12/30/2008
"Great bucking!!! I think it is as good as a firefly bucking hands down. Definitely recommend it.
by THE TL D. on 10/29/2008
"The god of Buckings. If combine it with a firefly nub and you have the pwnage.
by Howard H. on 05/02/2008
"Very good hop up bucking at a great price, the only ones that are better are the Prometheus Buckings and Firefly bucking. But these are both at least double the price so why bother, very high quality, but when installing use some silicone oil because the rubber tends to be rather dry and hard to insert into the chamber.
