im selling my tippmann, but keeping the r/t, and i decided to give it to my brother for his birthday which is tomorrow. When i was screwing in the two little screws into the chamber, somehow the internal part of the chamber stripped

. Do the screws go all the way into the chamber, meaning it will leak without the screw? or are they just there to hold it in place? i need an answer asap bc like i said its for his birthday which is tomorrow.
