Dust Cover Won't Close

G&G models in the GR and Top Tech/GT line can come equipped with a blowback module, which makes the dust cover kick open upon actuation. The charging handle is linked in, so actuating it will kick open the dust cover. CM series guns do not come equipped with a blowback module, and the charging handle is not linked in/just for show.

If the dust cover is sticking, it can be caused by one of three things:

-Wear on the locking tab on the dust cover. If the unit is worn down, it will no longer engage correctly in the receiver. This is the least common occurring issue.

-Injection flash/shape irregularity on the locking tab on the dust cover. The opposite of the previous point. I've seen a few tabs that don't engage correctly, and are light/temperamental in staying closed. This is usually fixed easily enough by cleaning it up so it engages correctly with the receiver.

-Bent/misshapen blowback plate. I've seen a few guns where the owner has been a bit rough when separating the blowback plate from the gearbox, and bent the plate. This will usually result in the plate not traveling freely, affecting blowback stroke, but if the section that interfaces with the dust cover tab is out of place, also can cause the plate to perpetually "open" the spring loaded locking tab. This is the most common issue I've seen.

Regardless of cause, the function of your rifle will not be affected by the dust cover remaining in the open position.

Wow thanks for all of this. Is there anyway to tell which it is?

Without inspecting the rifle in question, no.

Any chance youll be, or anyone who can take a look at this, will be at the 24th bf4 scenario game?
