Hey guys,
So I've already built a very reliable AR-15. Well, I built the lower and bought a complete upper (all from PSA). Now I am building an AR-15 pistol lower (it'll be in 5.56 to start), and I'll be buying a complete upper from PSA in a few months time when I can afford it. I am building this AR pistol with the intention of putting a 10 inch barrel and a carbine length gas system on it.
My questions are as follows:
On an unrelated note, my cousin has an AR that seems to be a tad under gassed. The gun will cycle just fine, but it won't always lock the bolt the rear. My question with this is: would he need a slightly heavier or lighter buffer? I think he has a "standard" buffer and buffer spring. Do they make "weaker" buffer springs? If we cut of a coil of his buffer spring would that get the bolt to lock back every time? I am not sure how to solve this problem...
Please help!!!!
Any insight would be greatly appreciated! Thanks guys!

My questions are as follows:
- Are carbine and pistol buffer tubes the same length?
- Are carbine and pistol buffers the same weight and length?
- Can you interchange buffer springs and buffers between more average pistols and rifles without having feeding changes?
- I know that PSA's uppers are usually over-gassed, should that change the weight of buffer I should use?
