Sierra Foxtrot Posted August 28, 2016 Share Posted August 28, 2016 I would like to install quad rails onto my G&G Combat Machine M4 Carbine Light and I'm wanting something that can be confirmed as a drop in replacement requiring no modification on my part. I'm wanting rails that mimic the KAC RAS or RIS. JG has a M4 quad rail which is in stock at Airsoft GI for a great price, but again, I'm want something that can be confirmed to fit on the G&G Combat Machine M4 Carbines without any modification required. I'm wanting to know because I've been down this road before with other AEG's and I do not wish to go through the trouble performing any modifications, and I do not wish to purchase any other AEG's at this time.

Guest PT247 Posted August 28, 2016 Share Posted August 28, 2016 I think the front iron sight is fixed on the CM M4s? That may make it difficult to swap stuff around. Link to comment Share on other sites More sharing options...
Jam_Man Posted August 28, 2016 Share Posted August 28, 2016 Not sure if this is the model you have but they show how its done here. I think the front iron sight is fixed on the CM M4s? That may make it difficult to swap stuff around. The front site does need removing though as per above its moulded on some of thems so you may need a new outer barrel?

Supporters Sitting Duck Posted August 28, 2016 Supporters Share Posted August 28, 2016 On the CM Carbine's & Raider's the front sight is cast into barrel and not removable Well you can hack it off but a bit of a bodge..... you could hack off most of it all and hid it in a 10" keymod maybe BUT On top of that your gun is front wired so a RIS will give you reduced battery space might be ok at a push if your batteries are thin twin sticks - maybe lipo but nimah's but be a bit cramped in a RIS or rail system Yes I know there are some with more room than others - but just pointing out stuff There are the magpul clone handguards out there but may need modding to fit TBH - its a shorter carbine gun, well suited as a cqb-middle range size gun But for what it is worth - I would be inclined to just run with it as it is any money you might be thinking of sinking into this I think I'd just chuck it towards or part ex on another gun not saying you can't do this or that with it - more a question of where you start/stop on a CM Carbine or Raider Link to comment Share on other sites More sharing options...
HSCtheta7 Posted August 28, 2016 Share Posted August 28, 2016 http://www.patrolbase.co.uk/airsoft-outer-barrel-ris-rail-systems-hand-guards/asg-m4-m15-shotgun-vsr-m14-handguard-rail.htm#.V8Neg7xwbIY The thingy above is a piece of rail that attaches directly to the standard handguard, through the little holes in the bottom. Might be an alternative to the KAC drop-in part. If you still decide to go with the KAC one, either use LiPos (as Duck says) or get an external PEQ box.

Sierra Foxtrot Posted August 29, 2016 Author Share Posted August 29, 2016 Why would one need to remove the front shight block for quad rails? They should be a drop in fit. Link to comment Share on other sites More sharing options...
