Thread: AR-15 AIL/Servo Stock Installation Help

Hi all,

I don't have much experience with altering AR-15's so bear with me if these seem like stupid questions. I have a lower which had a Rock River Arms CAR adjustable stock on it and want to swap this out for the AIL/Servo A-Cat stock (fixed not the new adjustable one). Upon trying to do this tonight it appears I need to also purchase a different (A2?) buffer tube? My questions are:

1. Can I use the parts in the CAR stock (buffer and spring) and just buy an A2 buffer tube?
2. Do I need a buttstock spacer that is required for an A2 stock or is that not needed for the AIL stock?
3. I'm guessing the lock plate and castle nut will no longer be needed?
4. Where is the cheapest place to buy an A2 buffer tube?

Thanks
CT
