Avengers B-33 Articulating Railed Dust Cover for AK Series Airsoft Rifles (Color: Desert Tan)

"Got it for E&L AKS-74N

I've got this along with the Avengers SPORT 4. Installing it is very simple and with the E&L and the SPORT 4, it installs flawlessly. The dust cover closes with no problem and also gives the gun a bit more battery space. The biggest problem with this though is that the set came with the screws but did not come with the washers so the screws will stick out even after tightening down the screws. However, even if you somehow had the spacers, the screws are a bit too long. The screws will touch the outer barrel and trunnion as you screw it down.

Pros:
Solid lock up with no wobble on the E&L with SPORT 4

Cons:
screws are too long and did not come with washers

"Doesn't fit CYMA AK's
That being said if you are comfortable with a dremel, you can modify it to fit well enough.
The rail itself is incredibly sturdy and articulates well
4/5 due to needing to modify it to fit undoubtedly the most popular AK manufacturer.

"Got this for a zenitco akm build using the WE AK PMC for the base. Using it with the Avengers Sport 4 kit. Some modification (dremeling down some material so it fit flush) was needed on both the Sport 4 and this dust cover. After some filing and fitting, it locked well into the WE gbbr base and still allows the bolt to fully travel. Keeps a pretty good zero after mag dumps and gives an AK space to put optics in a more traditional position. It honestly also just takes up a lot of the profile of the AK, and gives it a sort of modern facelift, especially when you're shouldering it and staring down the sights (also lets you keep original sights).

TL;DR
Requires zenitco style handguard
Works on gbbrs
Might need modification (idk it might fit aegs or other gbbrs better, I had to modify for WE)
Sturdy quality and clean look

4/5 since I had to modify the part, might work better for your situation
