SHS Airsoft Reinforced Tappet Plate For Version 3 Gearbox
Tappet plates can be a very important gearbox part, especially with high performance setups.  Your entire gearbox might be rendered useless just because your old tappet plate gave out on you.  You'll be smart if you upgrade to a high quality SHS tappet plate that will make sure your gearbox doesn't  die needlessly.   They're relatively inexpensive and well worth the small cost.
