Kross Airsoft Design Glock / AAP-01 Angled HPA Adapter

Six variant configurations make this one of the most flexible HPA adapters KAD produce. Angled magwell architecture cants your magazine, dropping the gun's silhouette and reducing snag risk on rig and gear. Pick your mag fitment (M4 or MP5) based on what's already in your kit, and your build comfort level (Adaptor Only, Fully Assembled, or Send Us Your Mag) based on how hands-on you want to be.

M4 fitment is the more common choice for shooters with an existing AEG/HPA primary running M4 mags. MP5 fitment makes sense if your other guns run MP5 mags or if you specifically want the MP5 mag handling angle. Both work equally well — the choice is about which magazines are easier for you to source and reload.

Compatible with TM Glock and Action Army AAP-01 platforms as the host pistol. Same adapter geometry fits both, saving the duplication of platform-specific solutions.

Why six packages exist

Different shooters want different levels of involvement. A skilled tech can pick Adaptor Only and have it fitted in twenty minutes. A first-time HPA convert prefers the fully-assembled option — plug it in and shoot. The send-us-your-mag option suits shooters who already own a great donor mag they don't want to retire. Multiply by mag fitment (M4 or MP5) and you've got six logical configurations that each suit a particular use case. Pick yours.
