Why upgrade to metal from the polymer bodies that the combat machines have? They're so much lighter, and can flex without breaking.
Cheap, and good, for metal bodies don't really go well togethor. You're going to have to spend quite a few $$ on a nice metal body.

Ok thanks for the advice, I have 2 G4's and was going to get a metal body for one mainly for looks but now that i think about it the polymer body in honestly one of my favorite things about the gun

One issue with the G4's is their polymer body. Most of the G4 series have a free float rail system which, on a metal body, is fine. However, if you put a free float on a polymer body, the barrel doesn't have much support and can sway very much because of the plastic being slightly flexible, therefore making your gun inaccurate.

Free float means it doesn't touch the barrel. It free floats. A good polymer body is going to be just as stable as a metal body. |

I know what a free float is, that just what I mean. No matter how strong a polymer is, it still has just enough give that could make or break a shot.

So, please enlighten me as to how a ris will effect a barrel when the two hardly come in contact? If anything the barrel may move slightly in the upper, because of the plastic flexing, but the contact area for the ris should actually help this when it's tightened down.

I'm with Pagan on this, the RIS especially if it is free-float wont affect accuracy at all (that is the point of free floating a barrel). Polymer bodies especially the kind on these G&Gs aren't going to flex enough to make or break a shot unless your putting some serious strain on the barrel and trying to take one specific shot at an extremely long range. In my mind this is beyond the expectation of the platform.
As Biz had said I would stay with polymer as it is a large weight advantage, especially for outdoor games. Metal guns get heavy fast. Maybe I'm just getting old but my TM AUG was full metal and at 8.5 lbs weighed me down quite a bit after a while.

Pagan, that's exactly what I'm saying. A standard M4 system's handguard is actually attached to the barrel via the handguard cap, therefore, the front hand is controlling the barrel slightly. With a free float, the barrel is only supported at the receiver, with the float system not touching the barrel at all. Normally this would make the gun much more accurate, since the operator's hand isn't "controlling" the barrel, and nothing is touching it. However, on the polymer bodies of certain Airsoft guns, the barrel is only supported at the receiver, which may have some give, as it is plastic. The barrel could move a bit more in a direction since it only has one point of contact with the gun. Several people that have purchased the GI-G4 have had this same problem of accuracy: www.airsoftgi.com/product_info.php?cPath=139_24_302&products_id=6097 |

It's obvious we agree to disagree on this one.
Personal opinions differ. I've personally gotten more wobble out of RIS that connect with a delta ring and a handguard cap than with free float systems, but that's just my experience.
I do agree with ehagendorff, that the amount of pressure needed to actually move the barrel enough to adversely effect accuracy isn't a common occurrence.

I see what you're saying Specter, and on paper you're completely right. The thing is in real world application the chances of that happening are extremely slim. The other thing I noticed was that you linked a DMR AR platform designed for long range, and the OP linked an AR platform setup for closer engagements or CQB. (little bit of apples to oranges here, let me explain.)
The particular DMR setup you linked would be more prone to the accuracy flaws you are talking about for two reasons. It is a much longer upper assembly (a little less than double actually at 20" compared to 10.5" the OP has.) increasing the amount of force applied to the receiver when pressure is placed on the barrel or muzzle. Think of a fulcrum such as a pry bar or car jack, longer length amplifies force at either end, requiring less overall pressure to affect accuracy than with a SBR. Also, that platform is setup for taking accurate long range shots which is going to amplify any adverse affects on the rifles accuracy. The longer shot you are trying to take the more stable everything needs to be when you break the round off.
These are the very reasons free floated stocks and assemblies were made. The need to accurately place a round down range at 700-1000m drove a need to change the way rifles were accurized. By free floating the barrel you can rest the stock on a rest (bi-pod, branch, log, bench) without placing upward pressure on the barrel affecting POI down range. Of course this is for firearm applications. This should not be an expectation of the platform owned by the OP. Again, apples to oranges comparison here in my mind, DMR vs. CQB. *shrug*
The biggest factor when it comes to airsoft accuracy is the ammo and wind. Bottom line, we are still shooting 6mm plastic spheres that weigh less than a gram no matter how heavy of ammo you run to a range of about 100-250ft. You have a MUCH higher chance of having wind drift affect POI downrange than a "flexible receiver". Free-float systems are going to have a negligible affect on real-world accuracy in airsoft, and they are applied more for authenticity than an accurizing method. Again, on paper, or in theory they improve accuracy.
The other thing that will affect accuracy more noticeably than a flexible receiver is moving parts. You want the muzzle as stable as possible when taking a long range shot. This is why bolt-rifles are used for extremely long range shots most of the time, less moving parts. The firing pin drops and that is all that moves in the firing assembly until you cycle the bolt manually. In an automatic weapon the bolt assembly cycles as soon as the round breaks moving the parts of the action as the round is leaving the barrel. A negligible difference now a days, but if we're talking about getting truly accurate shots, it is a factor.
This difference can be realized in airsoft if you're splitting hairs, a bolt rifle has less moving parts than an AEG and are inherently more accurate, especially when you consider the fact that the gears wind and compress the spring before the round is fired. Once the piston drops the round is sent down range and the action stops moving, but the entire time the rifle is lined up before the shot the parts are in motion. Real world however you have a higher chance of gas or spring inconsistency affecting POI than gears winding.
Again, on paper and in theory everything makes a difference, in the field..don't sweat the small stuff.
