Wii Tech アルミ ホップアップ チャンバー 東京マルイ M870 用

Material：Aluminium
Weight：7 g

This aluminium Hop−up chamber fits the original version M870(T.Marui). It does NOT fit the new version (2015) M870 loading nozzle because it does not have a small centre hole. For the new version (2015) M870(T.Marui), you need this Hop−up chamber together with our Power−up Loading Nozzle (i.e. #4045T, #4045).
This item is manufactured under CNC process and:
1) suits T.Marui M870;
2) improves smoothness of loading BB;
3) increases hop−up performance;
4) strengthens construction and durability;
Remark: for the best air−tightness in the hop−up chamber and smoothness installation, please put some lubricating grease all around 3 hop−up buckings and barrels inside the hop−up chamber.
