CM028U help

[Thornie]

So I’m currently trying to figure out a way to get a rear rail on my 028, most forums I’ve come across have been ancient and have said I’d need to drill the upper cover to mount a rail. I’m trying to avoid this at all costs as I don’t want any clearance issues with the battery. I have found this but it’s for the cm045 (AKS-74U variant) and I haven’t a clue if it’s fit from what I can tell it looks like it should but was just wondering if anyone has any knowledge on this?

You have not included a picture; however, if it is a railed cover for a CM045 it will not fit on a CM028U.  The 045 dust cover is hinged at the front.

theres these unless this is the one youve already found, it looks like it should have a hinge but really it should fit fine just adds an extra layer to the gas block at the front

if you go on sixmm and search for that railed dust cover you will see a picture of it on a regular sized ak

Oop my bad. https://www.patrolbase.co.uk/cyma-20mm-railed-top-cover-for-cm-045-aks-74u-aeg

the main thing I need to know is if the actual cover fits on. In theory I can trim off the hinge as it looks like it’s attached to the rail not the cover itself.

So the actual covers (without rail) should be the same dimensions? I wasn’t sure if the 74 was a bigger or smaller gun than the 47.

If you trim the hinge off, there is not enough material on the dust cover to fit into the curved slot on the back of the CM028 trunnion.

However, the one that BIGwat has linked to 'should' work; my son has one fitted to a CYMA 04x series AK105.

 no the 47 and 74 take the same parts with high compatiablity with different brands unless its ics, both are interchangable between its just a preference thing on what you like the look of 

the only thing youll have to do is remove the rear iron sight as that sits on the gas block
