Yes the too high pressure HPA one ?. I think the price varies quite a bit - someone on prefired has recently put one up for sale for £900
Yup, I’ve bought and sold about 12 in the last 18 months.
About six months ago was peak price, a fair few have come on the market recently when people realised how much they were going for.
Naturally, more on the market, less rare, the price has comes down a bit, so I stopped selling.
I’ve never seen one publicly sell for £900, not to say it won’t of course, I sold a new, unfired until I tested it, one last year for £750 with three brand new mags and Hephaestus recoil kit, along with all the original parts and box, the one on freeads is very similar and not selling at £475.
The cheapest I’ve bought one for is £200, needed a bit of fettling but essentially complete.
