Matrix C79 Type R.I.S. (Rail Interface System) for AK47 Series Airsoft AEG

"this is great! it fit my cyma cm028 with no modifications needed and has a nice tight fit. for 25 dollars i couldnt have asked for anything of higher quality. they are solid and are good. i cant wait to take em out on the field.
pros-
durable
fit well
looks sick and fit any 20mm rail attachments.
cons-
none as of now.

"This is an amazing R.I.S.
its only $20 and it looks like it would be cheap plastic, but it is actually all metal and comes with a black ak pistol grip. the grip is plastic but its very good and hard.(TWSS). the whole thing is sturdy and stays on. Overall, very good rails. But i think they sent me the $40 version

"Misleading description. Even though it’s labeled for being compatible with ak74’s, it did not fit for my CM.040C. The front sling post ring got in the way of the lower hand guard and the rear end of the guard does not have the right structure to fit into the receiver so it just hangs there. And if the lower hand guard can’t go on the rifle then the upper railed gas tube cover can’t fit onto the gun either. Although I’m sure it would fit fine on an ak47, it does not fit AK74’s like it said it would.

"got this for my cm047c (ak74m) and it didnt fit out of the box. The front sling post got in the way and the rear end of the bottom rail didnt fit up with the body right. The rails are made of plastic so it is possible to file them down to fit. Theyre solid rails for being made of plastic and i would give a 5/5 if they fit right
