But... the head is black. Maybe an FDE beam cover would hide that... but the endcap for the remote pressure pad (

I guess that with the Toy Soldier SU233 stickers it should be a decent repro.
I'll think about it... but I'm tempted to get the Element SF M961, it's much more lumens for my bucks^^
If anybody has a King Arms M3, let us know if it works well!
