Maple Leaf AST Macaron Airsoft AEG Hopup Rubber Bucking (Type: 70 Degree)

"VERY GOOD. This bucking increased my FPS on all my guns by 30-35 FPS. Very surprised it did that because not a lot of buckings can do that. I got the .60 degree yellow bucking for my AEGs shooting 300fps and lower. This is the little FPS boost you need

"best and cheapest upgrade for any gun out of the box, practically an rhop, this and a 6.03 inner and youll be set. only thing worth noting is if your going to get it, id recomend the 75 degree model, i had misfeeds with anything less on some guns. super weird, but this is one of the single best upgrades you can do and you can compete with the "big boys" as far as range and accuracy goes.

"Works great in my emg retro arms rotary hop up with a 6.03mm barrel easy 250 feet shots
