Brownells mil-spec 6 position buffer tube has a comfortable cheek weld for extended range sessions. The QD socket holds a sling without play. Threads to a standard milspec castle nut. Anodize is the standard matte black. Budget tube that works.
Plain milspec buffer tube from Brownells, does the job for a budget build. Threads were clean and lined up with my castle nut without any binding. Six positions click positively. The integrated QD point is only on the left side which is fine if youre left hand carry but odd for right handed.
