Have a look at that, its my bb gun that i recently made with a bb reicever that i macined just the insides thought. It has got a moving piston inside the reicever so it pushes the bbs up to the barrel every time i take a shot but some times it shoots doubles but thats only some times.
Im using my phone so sorry for some spelling mistakes.

Incorrect, the T fitting i am using is 1/4" NPT. The BBs fit perfectly, without any modification.

you should go up to 3/8 or 1/2'' to alow air to flow around the bb behind the one stuck in the dent.

I will have a look at the T piece, as it may be that only one BB can fit in the 'chamber' with none behind it. It is an amazingly tight fit, almost like it was made for it.
