AAP-01: XP-02 Airsoft Bullpup Kit

Continuing on my design work for the AAP-01 airsoft toy, I would like to present to you my work over the last year and a half:

The AAP-01 Bullpup Kit - XP-02 (Xperimental Pistol).
This kit introduces more quality of life improvements and better functionality. Thanks to Ughh and other customer feedback, the kit is much more improved over the XP-01.

Recommended upgrades by Ughh:https://cults3d.com/en/3d-model/tool/xp-02-extra-files

Legacy: The AAP-01 Bullpup Kit - XP-01.

Goal: To make a small form-factor sized bullpup for mil-sim vehicle use and CQB. It's also a cost-effective GBB pdw.

This is a step away from the free models I usually make because this project required much more effort and much more patience. I hope you all enjoy it!
Many of my prototypes and renditions are in the photos.

This also removes the lower pistol receiver in place of a modular receiver for more configurations for more of my designs in the future!

This is the first working rendition I am willing to post. I will be updating this more in the future to tighten up tolerances.
