Only buffer tube i ever need! - Primary Weapons Systems PWS Enhanced Buffer Tube, Mil-Spec Gen 2 Ratchet Lock Endplate

I don't even buy other buffer tubes anymore. U don't have to torque or anything. So easy to get your buffer tube aligned. U just hand tight it. The ratchet clicks and u have to use a lot of force to back it out. So its on there. (Definitely love it because I hate when you torque a regular buffer tube and castle nut and the buffer tube gets all crooked. This won't do that because it only has to be hand tight.

The tube on the inside is super smooth. Will reduce all that spring noise you hear when pulling back the charging handle.
