ICS in their infinite wisdom decided to make the L85 with a different barrel to everything else.
since then they have changed the design and now use the same as the the others.
the 2 plastic clips are all that you need to convert it to be able to use a precision barrel.
if you find someone who has these two plastic clips you can upgrade to anything. i got mine from my usual ICS supplier in the UK for £6
the length is slightly smaller to the M16 so if you go for that one and just cut the end off.
hope this helps
