The Hop-Up Chamber from APS Airsoft was developed for the Barrett Fieldcraft sniper rifle. However, due to the design, it can also be installed in Tokyo Marui VSR-10 or similar rifles. The Hop-Up Chamber is made entirely of metal and comes with Hop-Up Bucking and Chamber Block. Ideal replacement part if the original Hop-Up Chamber has been damaged.

The Hop-Up Chamber is delivered assembled as shown in the photos.
