The nice design feature in the Marlin, compared to the Winchester, is that the receiver top is closed. This allows scope mounting. AND the bolt slides out so it's possible to run a cleaning rod from the breech end.
There's an ejector spring sitting in a groove behind the bolt. Don't neglect to remove it when cleaning, replace it when done cleaning. It press pins into a slot and is easy to overlook. It gets knocked out of the way with a cleaning rod and is easy to misplace.
I've had two 1894's in 44 mag. Sold the first one to buy a kayak -- that was a mistake. I'm keeping the second one.
Locally they're referred to as the "redneck assault rifle" . . . short, small, light, quick, 10 rds. And they don't scare the bejeezus out of the sheeple.
