6 Position Buffer Tube at a Great Price

I bought and installed this 6 position buffer tube on my last 3 AR15 builds. Buffer tube is excellent quality and AT3 offers this at a fantastic price. I recommend pairing this up with a Magpul CTR butt stock.

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