Wasn't where to put this add?  If it's in the wrong place please point it out so it can be moved?

Got this upper receiver a while ago.  I have a few Marushin AR15 Shell Ejection type replicas that I have collected.  They didn't do an M4 type only the XM177 type so I got a spare upper and converted it to a flat top with an airsoft M4 top rail.  This was glued on using JB Weld after cutting the carry handle off.   I also cut the brass bump off a broken plastic M4 receiver and JB Welded that on to so it looks correct.  I fitted an airsoft M4 front end on and then painted it.  It fits all the handguards I've tried on it, from the original XM ones, the fatter M4 ones, Magpul ones and the Kac rail ones.  If you know ya Marushin models, the stock tube is slightly smaller so I have glued card tube inside an M4 stock and it fits great.

I have shown a few pictures of what it looks like on the standard XM177 lower so you get an idea, but essentially it's just the complete upper, Kac rail and stock available for sale.

Looking for £70 posted or £60 posted if you don't need the stock?

I never fired this while on my gun, neither the other too tbh, so I cannot guarantee that you will get this working,  it's more of a show piece really, but you never know, if ya skilled enough?
