"I recently installed this hop-up bucking on my SSG build, and the performance has been outstanding. Using .25g BBs, I achieved impressive groupings with excellent range, consistently hitting center mass from considerable distances.

However, when I transferred the bucking to my Polarstar F2-equipped Cyma SR25, I encountered some issues. With the Maxx M4P Pro hop-up, the performance became inconsistent. If the hop-up wasn't adjusted precisely, shots would initially fly straight up, then after about four shots, they would start to under-hop. Occasionally, two shots would be perfect, but this inconsistency was frustrating. I was using .32g Tippmann Eco Green BBs at 80 PSI, producing 1.5 joules of energy.

In summary, this hop-up bucking excels in AEGs, particularly with heavier BBs. The aggressive contact patch shows great potential for optimal performance with heavier weights. I highly recommend using it for AEG builds, ensuring you pair it with the appropriate BB weight for the best results.

"I have gone through about 20 different buckings, not to mention 20 different barrels over the past year while tuning my HPA G28 ("DMR" Platform).

I was hopeful due to the adverts created and the hype on different forums, however, I was running into consistency issues with my system and this particular bucking.

I attempted to install it in different configurations to attempt to remedy the issues I was encountering, however, I did not come to a complete resolution.

Using this in the Begadi Hopup and all 3 different MAXX hop-ups (ME-PRO, New P*, and AEG models) I encountered a phenomenon where a few shots would be fine, then one would over hop, then directly after under hop a few more times.

I installed a Maple Leaf Super Silicone, and my system ran perfectly proceedingly.

I did not try this yet in a different system, but I will be sure to update when I do so.

PROS
- Quality rubber
- Nice packaging
- Comes with a nub

Cons
- Hop inconsistency issues (Need to try in different systems)
