Hello, I have on order, the above air rifle. I have read and seen many reviews but what has not been mentioned ( if it has, I've not seen it ) the trap in the butt plate.
Is it as it should be i.e., big enough to take the oil bottle and pull-thru?
Might help if you posted a link to the rifle in question, especially as you've stated it's 4.5mm, an air rifle, & this forum is primarily focused on 6mm Airsoft equipment ?
