Selling a fully operational, lightly used V2 HPA conversion kit by Frog Engineering, dedicated for VFC AR15/HK416 series replicas.

What's included:

Conversion kit with mounting screws
Trigger guard with mounting screws (FDE color)
Modified HK416A5 pistol grip (can be swapped for another grip after modifying it to fit the HPA line)
HPA line with a pre-installed connector
7 fully working magazines dedicated for this conversion (FDE color)
Speedloader
Spare parts (various height bolt catch arms and a spare wheel for the speedloader mechanism)

Note: You can find instructional videos on installation and performance on Frog Engineering’s YouTube channel. Additionally, 3D printing files for spare parts are available on their Cults3D profile.

Condition & History:
The kit has just been removed from a VFC HK416A5. It has a very low round count, around 1,000–1,500 BBs. The conversion was originally installed on the replica by Frog himself.

For those interested, I can provide a video showing how the kit functions and shoots while it was still installed.

Reason for selling: I’m letting it go simply because I couldn't get used to running a tank and line setup.

Shipping:
Shipping is on buyer, items are in Poland.
