do both of them support propane?

Both are metal and made for propane (or HFC22).

2 things 1 the ics m4 is a great gun i have had mine for 1.5 years my main aeg use it all the time and have yet to have a problem with it i like it alot more than the tm gun i have and never use. seccond keep in mine that black is not cammo. black is the absence of colour and never occoures in nature. yes black guns look good but if its cammo u want consiter painting it

Get a TM SR-16 and a KSC G19 with a Metal Slide

Is there any place i can buy a TM M4A1 and ask them to upgrade it to a full metal version before they ship it out?

that would be hella expensive

thas why ill just stick to the ICS M4, or the G&G M4, or the CA M4

G&G... take down was unparalleled by any other stock gun i've handled.

or G&P, but I don't know if the takedown is the same.

G&P's M4 takedown is a matter of TWO body pins IIRC. I havent play with Prowler's M4 in a lil bit but thats what I remember.

now correct me if i am wrong but are G&G way to hot for indoor play. alot of players on the team i play with have ICS and there good guns from what i am told. but i play with TM and only TM and there good guns. as for a pistol most of my team mates told me to stay the hell away from KJ M9s but they're glock are amazing. but i like WE out of all the pistol i have got to shot and hold there metal, cheap and kick ass.

i have a KJ-HEAD(jap version) M9 elite and i love it...not full metal but the slide is..hop up is fixed but still good...

well im a fan of full metal berettas, but i only want to be paying under 350.

each?

Ok, here's my dilemma: I have about 3-4 guns aegs i can't choose between. First off im looking for a Fulll Metal, Powerful, Reliable, and Good Build Quality. I've come to the desicion of these aegs:

G&G GR16 Carbine:

Length 790.0 mm
Capacity 450 rds
Power 350 fps

Shooting Mode Semi, Full Auto

G&P M4A1 (Extendable Stock):
PLEASE NOTE: This rifle is preupgraded to shoot ~410fps. We recommend an 8.4v 2400mah battery.
This G&P M4 series rifles come with full metal body, much higer quality engravings. Extendable stock allows you to adjsut the length of rifle to fits your body! Comes with a 130 round high capacity magazine. Metal flash hider can be screwed off for installation of a 14mm counter-clockwise threaded silencer, just like the Marui M4A1. Dust cover can be flipped open to reveal hop-up adjuster.

Hop-Up ADJUSTABLE Weight 4,900 g Length 760.0 mm Capacity 130 rds Power ~410FPS Motor EG700 Battery Size 8.4v600mah Shooting Mode Semi, Full Auto

I will not be upgrading the guns any further so i want a gun that can be used well in the field and indoors without alot of mechanical problems.

Thanks

I dont think i want to purchase a TM and upgrade the body and internals so thats out of the question.
