The 2.0 chamber by Maple Leaf delivers maximum accuracy for airsoft sniper rifles VSR. Thanks to precise CNC machining from aluminum alloy, it offers excellent durability and production accuracy.
Side-mounted arm, like in the original chamber, allows quick and precise hop-up adjustment, while the second adjustment option is through the TDC system directly above the chamber.
The TDC system (Top Dead Center) applies vertical pressure on the BB via the hop-up bucking nub. It optimally distributes pressure directly above the barrel window, unlike angled pressure arms. This allows players to achieve greater shooting accuracy and stronger hop-up effects, even with heavy BBs, for each shot.
Included CNC pressure arms for both side and TDC adjustment methods enhance BB flight stability and overall weapon performance. The CNC anti-double-feed stopper prevents double feeding, ensuring your rifle is always ready to fire.
The chamber is compatible with GBB/VSR hop-up buckings, allowing further customization. We recommend trying the Maple Leaf GBB Wonder and MR HOP buckings for maximum rifle range.
For TDC adjustment functionality, you need to manually drill a hole in the outer barrel directly above the chamber (must be perfectly vertical) or purchase an outer barrel with a pre-drilled TDC hole. Installation instructions are available in the video tutorial.
