For sale Rifle GHK AK74 TWI Bullpup AK Kit (Kochevnik)

GHK AK74 TWI Bullpup AK Kit (Kochevnik) purchased back in 2017 and kit fitted more recently. It’s been fielded once and been a garden plinker ever since. Has probably had a max of 2k rounds through it and that’s putting in generously. Has developed an issue hence why it’s being listed as boneyard. After the last shot to trigger disengages and needs to be striped down and sears worked to release. Search the forums and it seems a common issue with these but it’s not something that’s in my wheelhouse to fix. Comes with original gas mag and 4x co2 mags all work. Comes with 1j nozzle and original folding paratrooper stock, pistol grip and top part of the foregrip only.
