Separating the Upper and Lower Receivers

The receiver is the main body cake at the heart of the M4 rifle. The receiver can be separated into two: the upper and lower receiver. The upper receiver is the zipper point for the front track/handguard, the external barrel, the inner butt, and the hop-up. The lower receiver carries the gearbox, the rear shoulder stock, motor, and handgrip.

To dissever the receiver, tap out the receiver pivot at the front of the receiver, correct under and behind the track/handguard. The photo below shows the receiver pivot tapped out slightly.

Once the receiver pin has been completely tapped out, you can pull the upper receiver forward, while pulling the lower receiver backward. On some M4 airsoft guns, information technology is very tight. You tin can put the forward assist push to adept use in this case.

The frontwards aid button is the round button on the right side of the upper receiver. It does nix on an airsoft gun (at least on nigh airsoft guns; some realistic training airsoft rifle make use of it). Agree the handgrip with your right hand. Hold the rail/handguard with your left mitt. Use your right thumb on the forward help button. The receiver should separate with some pressure.

Unscrew the two small screws to remove the plate.

Next, you accept to remove the bolt catch latch mechanism. Pull the gearbox out of the receiver slightly until yous have revealed the latch (come across photo below). Unscrew the screw that is keeping the latch mechanism in place.

Switch the firing mode selector to semi-auto; otherwise, it would be difficult to get the gearbox out of the lower receiver. In one case you've done all that, y'all can now wiggle the gearbox out of the lower receiver. Be conscientious the wiring does not catch on the lower receiver.

Unscrew all of the screws on the gearbox (run into photo beneath). If you tin can't remove the spring first, hold the gearbox shell down as you unscrew the concluding screw.
