PTS MEC GBB Hop-Up Bucking (Pack of 2)

SKU ME111450300

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 TM MWS AR-15 Series, TM Hi-Capa 4.3/5.1, 1911, VFC/Elite Force/Umarex Glock Series and Sig Sauer P320 M17 and M18.
Two 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.
