Zero issuesSwapped this onto my duty rifle build replacing a commercial tube that came on a parts kit I bought years ago. Night and day difference honestly. My B5 SOPMOD clicks into every position with a rock solid lockup and absolutely no wobble or rattle. Threads were clean, the anodizing looks good, and it torqued down to spec without any drama. I've been building ARs for about 15 years and this is exactly what a buffer tube should be! Nothing fancy, just properly made to the right spec.

Quality buffer tubeThis is a solid mil-spec carbine buffer tube for AR-15 rifles. The 6-position adjustment gives you plenty of options for length of pull customization. The tighter fit over commercial tubes is definitely noticeable and the lockup is solid.
