ScouseReaper Posted September 6, 2018 Share Posted September 6, 2018 Hi people, Hope you're all ok, I have just had my cm16 intermeadiate delivered and I'm trying to take the keymod off I followed a vid online of a similar weapon but I haven't had the result I'm after (see pics) The guns now in two parts and I thin black peice of metal fell out from somewhere while I was trying to put it back together. Can someone please let me know what the piece and where I need to put it? Also how the hell do I get this keymod off so I can put a suppressor on? Regards A stressed newbie 😣 Link to comment Share on other sites More sharing options...
Supporters Gepard Posted September 6, 2018 Supporters Share Posted September 6, 2018 It's the dust cover that sits inside the receiever. When you pull back the charging handle it moves the cover, exposing the gearbox. In my experience it can be a bit of a pain to put it back in.

Iceni Posted September 6, 2018 Share Posted September 6, 2018 It's a cover for the gearbox. Totally non essential. It should be sat on a slide above the gearbox so it can be viewed through the ejection port. Personally I remove them and flip the spring on the cover. This means the cover is always closed and you have to get a finger nail on it to open it. But it also means water and dirt has a harder time getting into the hop area.

Check there’s not a grub screw underneath. In fact, that looks like a grub screw on the side in that very dark photo. Also, Threaded barrel is probably COUNTER clockwise thread. So turn it clockwise to take off. Link to comment Share on other sites More sharing options...

ScouseReaper Posted September 6, 2018 Author Share Posted September 6, 2018 Grub screw, just wouldn't budge at all, I've given up for the night, the dickhead that tested it has tightened the screw to the battery compartment that hard I can't even test the damn gun.

Mostly Retired Moderators L3wisD Posted September 6, 2018 Mostly Retired Moderators Share Posted September 6, 2018 ENHANCE! If you can't get enough purchase on an Allen key on this, stick a rubber band over the hole first, then stuff your Allen key in the hole. Should help it grip enough to get it undone. Also, it's worth considering that there are stories of these things being held in with a threadlocker (loctite etc), but I'm not sure if G&G fall foul of this.

Iceni Posted September 7, 2018 Share Posted September 7, 2018 Depending on the screw I interchange between proper keys and a 1/4 inch drive ratchet with a screwdriver bit adapter. The ratchet has the advantage of been every length you need, and still acting like a long key. A regular keyset in a hard to reach screw means you have to use the short end and often that can cause problems. If it is nutlocked in place then the application of a little heat with a micro blow torch will soften red threadlock. Doesn't need to be an expensive blowtorch, one of the jet style lighters should provide enough heat. Cheap keys are not hardened correctly, they tend to deform very quickly and round out. A decent set of basic keys doesn't need to be expensive either. If you have a Machine mart locally they have a decent selection of keys with lifetime warranty. So if you do break one you just walk back into the shop and they give you a new one. Might seem like a false economy but I use my set on my car as well and snap a few a year. Just been able to walk in and swap them is the key here, you don't mind paying more for that. Halfords do the same with most of their pro range of tools but not with the allen keys. Toolstation/screwfix don't do this in the same way you have to send them away but more often the tool range has no warranty at all.. £20 is still peanuts when it comes to tools. And knowing you can hoof on them and not be bothered about breakage is great.https://www.machinemart.co.uk/p/9-piece-colour-coded-extra-long-ball-end-metri/https://www.machinemart.co.uk/p/clarke-pro376-34-piece-14-drive-metric-socket-/ Link to comment Share on other sites More sharing options...
RR01 Posted September 7, 2018 Share Posted September 7, 2018 I was always under the impression that the CM16 had a moulded in flash hider that could not be removed. Has that changed? Link to comment Share on other sites More sharing options...
Supporters Druid799 Posted September 7, 2018 Supporters Share Posted September 7, 2018 As long as it’s metal stick some heat on the grub screw , that way if it has been lock-tight’ed on you’ll soften the lock-tight and it ‘should’ unscrew .
