Hello,
I have this kit i got from a member on the RPF and will need some help here to make it drop ready. I'me reading through all the old posts and archived topics first, but still have lots of questions.

Ther's still a few parts I need to get, like a metal barrel and some way to mount the GL, but there are some bits I can't figure ut what they're for (please excuse the crappy phone pics, camera needs batteries).


The piece in the middle is white plastic with 2 brass screws, the 2 other pieces appear to be steel.
I also only got 1 of these:

What's the easiest way to replicate this?
One last question for now, the resin shrouds have screw heads cast into the mag holder. Whats the consensus, should they be filled in or left visible?
Thanks,
Neil.
