This is mostly a firehawk with a few bits swapped out. 

The lower is a combat machine lower (as firehawks are) which was originally listed on here as a dead boneyard lower. It didn't sell so I fixed it. The trigger was not pushing the trigger contact forward (the trigger was worn or broken) so I replaced the trigger for a cnc aluminium one and added a laylax selector plate. The selector needed a little material removing from the front to allow the selector to move fully to safe. It's wired to deans. 

The buffer tube is not g&g but one I had lying around. The stock is a clone ctr stock with a real magpul exhanced stock pad which has been milled out to take a battery (it was a mission doing this!). 

The upper is a firehawk upper and firehawk barrel but the hop unit is a generic dial hop unit. It has a maple leaf macaron hop rubber (new and only used for this build). I only had up to 0.25g bbs to test with but it's sending these to the sky so I'm sure it'll do 0.3g no problem. 

It chronos as 310fps on 0.2g bbs and comes with a nuprol mid cap. 

The only issue I noticed when testing is if you squeeze the trigger very slowly in semi it is possible to full auto until you pull the trigger a little further. I suspect this is where the trigger contacts are making a connection but the contact assembly isn't far forward enough to get disconnected by the cutoff lever. 

I'm looking for £90 collected or £100 posted. That's about half the price of a new firehawk. Also a professionally milled out ctr stock is around £50 from memory. 

If you have any questions please ask. You need ukara or valid defence to buy this please.
