Aeros carbine kit comes with the buffer tube, spring, castle nut, end plate, and H buffer. Saves sourcing parts individually. The H buffer at 3.8 oz works on most 5.56 setups. End plate only has the QD socket on one side which is the standard layout but worth knowing if you carry on the other side.
Aero Precisions carbine buffer kit includes the tube, spring, castle nut, end plate and an H buffer. Saves having to source individually. The buffer tube has tight tolerances which made my stock stiff to adjust at first but it loosened up after a week of use. Now slides clean.
