Tippmann which is now GI Sportz are focused 100% on paintball. They have heavy investment in paintball making equipment.
How G.I. Sportz paintballs are made - YouTube The paintball industry is shrinking. If you have not noticed more and more paintball dealers are now offering a airsoft gun line, you don't see airsoft dealers selling paintball guns.
Airsoft is growing and GI Sportz is using the Tippmann past success to position a airsoft M4 which it is going to be out soon, but I have not seen any shooting or tech videos on it. Maybe it is a sign that paintball dealers will be pushing Tippmann M4's if paintball sales are down.
