As most of you may know, I am very fond of the AR-15/M16 series. I have a few different models in my collection and have done a few mostly cosmetic modifications.
I wrote about fitting real M4 foregrips as the grips MGC used were too thin. MGC simply used the molds they had for their XM177 and M16A1/M16A2 Carbine models (M725 Carbine), but the 14,5 inch M4A1 carbine uses thicker hand guards (you may notice that the M933 M4A1 Commando with the 11,5 inch barrel still has the thinner ones).


I also added a real AR-15 stock (no-name product, Taiwan made) to my MGC M733 as the original XM177 MGC stock rattles very badly (even worse than the one on the M4 series) and is too shiny.
Original MGC stock:

Aftermarket stock (tight fitting, dull finish) added:

My latest modification was done to the MGC M4A1 "RIS version". This is a model that was made in limited numbers before MGC closed down. It comes with a nice metal RIS rail system made by CAW - mosquito molds. This model is very heavy as the metal RIS adds more weight. It feels realistic, despite being HW plastic.
Out of the box (rather shiny stock, blued magazine):

After some work I did as I could not sleep once again:

I spray-painted the stock with dull black paint and added an old MGC magazine with black plastic follower and grey "mil spec" finish. Those magazines are very rare today and came originally with the ABS M16s. In realioty the dull stock looks much better than the photo suggests.
Here you can see the late blued magazine (zinc follower), the early grey "mil spec" magazine (black plastic follower) and a real mil spec M16 magazine (OKay 9/2003) with green follower. Note that the MGC magazines are not the same size and not as curved as the real one.

I really regret that MGC used to blue their late magazines, but I guess this was because the "mil finish" magazines tended to rust easily.
Please excuse the poor photos. As I said it is night here. Normally I prefer taking pictures outside in the daylight.
