Despite all the replies you still seem to be getting confused between UKARA and the VCRA. Scrapping UKARA would not allow anyone under 18 (or over 18 without a valid defence) to buy a RIF - it would just remove a simple system that allows a retailer to check that they will not be breaking the law when selling a RIF.
The regulations covering two-tones is in the VCRA and you would need to get that changed iif you wanted orange tips instead of full two-tones. for that you would need to get the support of your MP and probably get a petition going.
Why not spend a bit of time gaining some knowledge about all this - maybe rewad the information on this forum or on the UKAPU site:-

You may even find that the system does not need changing as genuine airsoft skirmishers can have RIFs without too much trouble.
