Frequently Asked Questions
What is the difference between a mil-spec and commercial buffer tube?
A mil-spec buffer tube measures approximately 1.14 inches in outer diameter and has a slightly smaller, more precise profile than a commercial-spec tube, which measures approximately 1.17 inches and features a slight taper. Mil-spec stocks and commercial stocks are not interchangeable, so it's important to match your tube to your stock. This LBE Unlimited tube is mil-spec diameter, making it compatible with the vast majority of aftermarket collapsible AR-15 stocks on the market today.
Does this buffer tube come with a buffer, buffer spring, or castle nut?
This listing is for the buffer tube only. A buffer, buffer spring, and castle nut/end plate are typically sold separately. If you're completing a lower build, be sure to add those components to your order. LBE Unlimited and many other manufacturers offer these parts individually or in complete lower parts kits for added convenience.
Is this buffer tube compatible with pistol braces or rifle stocks?
This mil-spec buffer tube is designed for use with collapsible rifle stocks built to mil-spec diameter standards. While some pistol braces are also designed to fit mil-spec tubes, compatibility varies by brace manufacturer — always confirm your brace or stock is rated for a mil-spec diameter tube before purchasing. It is not intended for use with fixed rifle stocks, which require a different tube design.
