Mil spec buffer tube, nothing special

Not perfect because there was a blemish on the threads (deep enough nick to show raw aluminum underneath). Acceptable because it'll be screwed into the lower and not visible.

Sorry to hear about the issue, PN. We can always help facilitate an exhcange if you could reach out to us.

Satisfied customer

I recently purchased a mil-spec Magpul Furniture kit from AT3 Tactical and after I received it I realized that my buffer to was not mil-spec. I then contacted them with my problem and they sent me one out as a reasonable price with free shipping.
Excellent customer service and I definitely will be ordering more in the future.

Thanks for sharing your feedback, John. We're glad you're satisfied with your purchase.
