whoa whoa... bro you went overboard with the decals on the Marasai !

The colour is actually pretty nice, better than the pinkish 1/100 or 1/144.

The proportions however is quite messed up. Shoulder armours are positioned too high, while the redesigned feet and spikes are hideous.

Oh well... save money.

Meanwhile... almost done with my HGUC Kampfer. Such an awesome kit for such a low price.

from the pictures it seems to be able to tilt forward and backwards slightly, but none of them showed any ability to rotate.

There are two bullpups that EFSF units use, and both of them fire 90mm calibre rounds.

The version used by GP01 and the GM Kai/Command variants has a shorter barrel with the clip located above the stock.
GM Customs and Quels carry the ones with a longer barrel and the ammo clip attaches on the bottom of the stock.
Both these bullpups have the same model number, yet they look very much different.

The only Zeonic gun I could think off which "looks" like a bullpup is the beam rifle carried by Rezin's commander unit Geara Doga, although being a beam rifle it's hard to say whether the firearm action is truly located behind the trigger like a conventional bullpup.

ReGZ's assault rifle looks like a bullpup although like the Geara Doga's, it is technically a beam rifle which doesn't work like a traditional solid round firing gun.

Speaking of gundam weapons, some of the guns used in the UC universe do resemble real life weapons, e.g.
Geara Zulu's rifle = Stormrifle / Sturmgewehr 44
Alex's unused beam rifle = FAMAS (although the Alex's rifle has the e-pac ammo clip located in front of the trigger hence non bullpup, unlike the FAMAS which is a bullpup)

now finally someone decides to give the Delta+ the correct rifle !!
