Most off-the-shelf bullpups suffer from poor ergonomics, large size, and poor compatibility. "Hey man, can I borrow a mag?" "Nah bruh, I'm using an AUG, the real steel one uses the same magazines as the M4 but the airsoft version is really weird so I can never borrow or loan mags."

NO MORE.

Bullpup 2.0 takes the internals of an HPA M4 and puts it into a bullpup format with an adjustable stock. It goes further by using standardized parts everywhere else. Pick out a rail kit, pistol grip, and trigger guard (or use the included file for a very basic one).

This also uses a similar mechanism as the Airsoft BR75 to provide more realistic trigger feedback by incorporating a tactile bump in the actuation. This simulates the 'break' of a real steel trigger.

This is the Bullpup you've been looking for.
