Ordered the PSA PA10 20" rifle kit. I know the trigger components are AR15 spec. Are the hand guards AR15 spec? I can get the full length rifle Knights rail for almost nothing, but was curious if they are the same size?
Thanks in advance!

The barrel nut diameter (1 7/16) and thread are not compatible with the AR15. They are compatible with the DPMS LR308. Since you need a new barrel nut to mount most rails, you are limited to those which fit the LR-308.
