Maple Leaf is a firm of the Taiwanese company RA-TECH known for its quality hop-up seals that deliver very good performance in terms of range and precision.
This kit consists of a high quality Hop up chamber sold with an I-Key tensioner and mounting bracket. Ideal for upgrading your GBB type 1911 airsoft fist replica and improving its performance.
Sold without an adjustment wheel, the block is compatible with your replica's original one but will probably require adjustment.
