Systema Hop Up Bucking for Airsoft AEG Rifles

"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
