We machine our Samurai Firearms Mil-Spec Buffer Tube from quality 7075-T6 Aluminum and finished them w/ Type 3 Hardcoat Anodize. This rigid and durable buffer tube conforms to all mil-spec standards and features 6 stock positions. This carbine length and mil-spec diameter is made in the USA, making it the perfect fit for your AR-15 lower and ensuring compatibility with most mil-spec diameter quality AR-15 stocks. Included in the package is a high-quality, mil-spec castle nut and end plate.

We manufacture our buffer springs from 17-7 Stainless Steel to improve the function and reliability of your AR-15 pattern rifle. The extra strength in that steel gives it a decreased tendency to lose length and force over a given round count.
