"Good bucking. I've installed two of these recently, one in an M4, and one in my G36c, and they work very well. I would recommend buying an H-nub to go with it. Very good product.

"Soft type of rubber great for gripping bb's. Put it in a gun shooting ~400 FPS and it's holding up just fine. Definite increase from stock bucking in grouping and range. I highly recommend this product to anyone.

"This is a decent bucking. I would say that it's worth the $8.

Cheap (cost-wise)
Feels sturdy
Decent air seal
Accuracy was improved a little
Comes with an aluminum barrel ring

Can be easy to tear (I never tore the exterior of it)
The "line" inside of it that aligns with the barrel tore off

"Evike no longer carries the original Systema hop-up buckings. They carry Systema Energy hop-up buckings, which are clear and made of thin silicon, designed for low FPS/high ROF setups. Keep that in mind if you decide to order this. It is NOT the bucking in the image!

The Energy bucking itself is ok as long as you aren't running a setup over 380 FPS. Past that though, I've experienced massive tearing issues. Buyer beware.

"I don't know if I just got a bad bucking or what, but as soon as I installed it I started shooting 2 BBs every 5 or 6 shots. The lip will not even hold a BB resting on the bucking alone. Installed my old bucking and my double BB shot problem was fixed.

"Garbage, utter rip-off. Won't fit right in the hop up, tears very easily, and overpriced. Like all other things Systema... Overpriced trash.
