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.

It's a buffer tube with six hole, what more do you want? Granted for the price it is a very nice product.

Mil-spec buffer tube

Ordered this buffer tube to upgrade to the buttstock with an OD Green furniture kit. Great price and a simple part to change out. Look forward to ordering more from AT3Tactical.
