Anti-tilt buffer tubes

[Dr. Lee]

Nearing the end of my 6.5 lower build, time for a buffer tube. Is there a real or perceived need for this item. It seems the piston guns benefit from them. What about a DI gun ? It seems to make sense to have the carrier being supported through it's complete travel. Then again ????

Will not help in an way. The carrier does not rub against the tube on a DI system.

Just get a quality MIL spec buffer tube. Read reviews to see if they complain about machine marks on the inside since that could hang up the buffer spring.
