PTS MEC AEG version - Hop Up Rubber Bucking (2-pack). A two-pack of buckings (one 60 degree and one 70 degree) for AEGs - see compatibility below (may work with more models)
The precision molded MEC Hop Up Rubber has a slightly narrower inner diameter at the entrance and extra coverage for the top of the barrel open cut area for vastly improved air sealing. Internally, it provides two equal pressure point of contacts with the bb resulting more effective range and more stable accuracy.
The MEC Hop Up Rubbers are compatible with all standard AEG hopup chambers.
Two (2) hop up rubbers are included. The black one (60 degree) is suitable for use in cool/cold weather. The purple one (70 degree) is suitable for use with heavier weight bb’s.
