Madbull Red Shark Hop Up Bucking | 60 Degree | 2PK Reviews

The Shark bucking and Fishbone X Balancer were originally developed for the MadBull 470 CO2 powered drop in mechbox to prevent double feeding of BBs and to prevent BBs from rolling out of the barrel.
By having 3 special "fins" inside the bucking, Shark Hopup Bucking can hold one and only one B.B. tightly in the chamber. In the mean time, to our surprise, we found that this bucking could enhance the velocity on some AEGs. Not all AEGs will have the same results and the result could be different from one AEG to another. Unfortunately, we don't know the exact reason because each AEG has its own characteristics. However, we do believe that the friction (from 3 fins) applied onto B.B. will increase and slightly build up the pressure behind the BB before it starts traveling down the barrel thus enhancing the velocity much like a blow gun, spit balls with a straw or similar concepts.Great product for use with Wolverine SMP, Wolverine Hydra, Protech MKII and Polarstar Jack.

This is my go-to bucking - I have tested and run countless buckings in numerous platforms and brands; aegs, Wolverine hpa, Polarstar hpa, Redline N7 and N7 milsim - both generations, the random off brand hpa engine in an M2 browning from PAF airsoft, Daytona, Tippmann. It consistently performs regardless of temperature. I almost always end up r-hopping, but it also performs admirably as a flat-hop. I toss the H-nub and go with a Modify flat. 10/10 recommend this bucking to anyone looking for an easy, effective performance upgrade.

Got this for my Redline Airsoft N7 MILSIM as it was suggested to me from my team. Nice tight seal and the nozzle fits and doesn’t cause any binding.

Put this on my rifle after getting the Redline N7 Milsim HPA engine. I was getting double feed issues, so I bought this to fix it. Works great so far!

I recently purchased this bucking for my polarstar jack that I play indoors with. The fps limit at my feild is 365fps and 1 joule for hpa with .2's. That fps was not high enough to push the bb through the bucking lips, which was causing jamming. The bucking preformed great at around 100 psi outdoors but indoors not so good. Would defiantly recommend it for outdoor use but not indoor.
