Hey, so with my UKARA still not registered. Been onto my local site for 2 weeks now and they still haven't done it. And I'm told it only takes 2 mins... ? anyway obviously my rifle still hasn't been ordered. But... I was originally wanting the mk18 version but the over used loctite on the barrel nut and the need for a URX tool has been putting me off, think I may be swayed back to a standard m4a1 as its so easy to access the inner barrel and hop up etc.. so got a question. I presume the gas tube running from the gas block/front sight back to the receiver is inert? Am i correct? If so is it possible to run the rifle without the front sight and gas tube leaving the hand guard / rail free floating. I'm not over keen on the front sight which is one reason I was going for the mk18. If it's fine to run like this it will make the m4a1 a more preferable choice for me again. As well as the fact its £70-80 cheaper. ( that leaves money for an extra mag

)
Thanks in advance.
