.300 Blackout Pistol Buffer/Spring Question

Neighbor called me up and let me know his new .300 Blackout 10" pistol build wasn't working. Not cycling correctly. He let me know that the gun fires, ejects, strips a new round and pushes it 90% into the chamber then stops. He has to bump the forward assist to get it fully seated. I'm assuming it is a buffer and or spring issue. He has a carbine length buffer tube and stock spring and buffer that came out of a misc box of AR parts. What buffer/ spring set up should he be using? I have zero experience with AR pistols so I can't weigh in on them much.
