Designing a new HPA kit for drop in units that will eliminate bad alignment and messy maintenance.
The whole system is designed to make drop in HPA systems a no brainer to install. Ptw style disassembly for easy engine maintenance and super simple installation etc. You van also shim the engine back to really tune the hop seal.
Soooooooo first impressions from some hoa guys out there. I'm currently in the testing phase for g&g, g&p and vfc versions for the n7, reaper, inferno and hydra. Fits spartan as well as regular electronics on the above mentioned engines.
The whole upper section is made of ultra durable tpu for insane durability and the lower is a basic htpla combo. All more than strong enough for the application.
