小型發射器300系列替換橡膠塞

Fits the RX-090 perfectly and doesn’t budge once it’s in place. I’ve had cheap plugs work loose in the field, but this one feels solid and worth the price for the peace of mind alone.

The fit on my existing 300 series unit is snug and secure, no wobble at all once I pressed it in. Took maybe two minutes to swap out and it feels like the original part, so I'm glad I grabbed this instead of hunting for a used one.

Exactly what I needed to replace the worn-out plug on my RX-090 receiver, and the fit is snug without any fiddling. The rubber feels durable enough to last, and it snapped right into place in under a minute.
