The Sons of Liberty Gun Works Intermediate 10-Position Maritime Buffer Tube is a receiver extension built for the A5 / Intermediate recoil system. It is machined from 7075-T6 aluminum with a durable matte black finish, and the Maritime drain holes let water and debris escape so the rifle keeps cycling in adverse environments.

Features:

• Designed for the A5 / Intermediate recoil system
• Machined from 7075-T6 aluminum
• Matte black finish
• 10 positions to fine-tune a stock’s length of pull
• Maritime drain holes at the rear of the tube
• Class 3A threads for a precise, robust fit with the lower receiver
• 7.75″ long, 1.35″ high, 1.148″ wide, 4.3 oz
• Includes one 10-position buffer tube

The ten adjustment points give you a range of stock positions for fitting the length of pull to the shooter, and the Class 3A threads give a tight, solid connection to the lower receiver. The “Maritime” name refers to the drain holes, which clear water and debris quickly from the tube.
