"This is a great bucking! Installed it into my KWA Sr10 and it worked wonders. I bought this bucking to obviously flat hop my AEG to increase range and trust me you will see a BIG difference.
Pros- Easy to install
Easy to sand down (if flat hopping)
Cons- It wore down WAY to fast.
I know that soft buckings tend to ware down aloft faster but I installed mine around March and I noticed HUGE tare on it which meas it wont hold a good air seal. Pretty disappointed. So I will advise other players who purchased this item, to check their bucking.
"Installed one in a metal G&P AUG / M14 hopup unit over an AEG barrel, and another to build a custom hopup for a revolver using an Orga widebore intended for the VSR-10. I flat hopped in both cases, which meant I had to turn the bucking inside out and carefully shave down the hopup bump inside it.
As they say, this is a good bucking, consistent and very durable, yet elastic. If you’re buying this item, you will probably be interested in at least flat-hopping your hopup, which is the one sort-of hiccup here. Once your bucking is sanded, you can sleep at night confident U R L33T 0P3R@ToR!!!
