i dis/reassembled my a5 for the first time and noticed it wouldent cock, i had the power tube backwards, so i put the gun back togeather and it cocked again!
when i shot my gun with no co2 in it, it mad an echoey sound not like the normal POP sound abd the cock handle was stiff and hard to cock back
also when i put co2 in, mind you the bottle was almost empty, i took a couple of shots and the gun sort of made this effortless shot sound and no white cloud came out of the gun and wouldent re cock itself, normally ,when youre low on air you can at least get a normal sound and it usually re cocks itself, but i dont knowm whats wrong


plz help me!
