Keeping Traditions Alive Since 1953

Most guys running an AR for a while eventually run into the limits of a standard 6-position tube, especially once you start layering on plates, packs, or just changing shooting positions throughout the day. Sons of Liberty Gun Works built this Intermediate 10-Position Maritime Buffer Tube to solve that problem by stretching things out to A5 length and adding four extra stops beyond what a typical carbine tube offers. That means finer adjustments and a much better shot at finding a stock position that actually fits how you shoot, whether that is prone behind a pack, standing with a plate carrier on, or just adjusting for a shorter or taller shooter swapping the same rifle.
This is not a standard mil-spec tube with a couple extra holes drilled in it. The intermediate/A5 length changes how the buffer and spring interact with the bolt carrier group, which is part of why the A5 buffer system has become such a popular upgrade path for guys chasing softer recoil impulse and better lock time. Because of that longer geometry, this tube needs to be paired with an A5-style buffer and a rifle-length or intermediate-length spring. It will not run correctly with a standard carbine buffer and carbine spring, so keep that in mind if you are piecing together a full buffer system rather than starting from scratch.
The maritime designation is not just a name. SOLGW added dedicated drain holes to the tube so that water clears out fast instead of pooling inside after a dunk, a downpour, or a long day of wet-weather training. That matters more than people expect, since trapped moisture in a buffer tube can eventually lead to corrosion or sluggish buffer movement if it is not given a way out.
Machined from 7075-T6 aluminum and finished with a hard-coat anodized coating, the tube is cut with Class 3A threads for a tight, consistent fit to your lower receiver. Sons of Liberty Gun Works has built a strong reputation in the AR-15 world for parts that hold up under duty and competition use, and this tube fits right into that lineup as a straightforward upgrade for anyone building or refreshing a lower with the A5 buffer system in mind.
No, this listing is for the tube only. You will need to source an A5-compatible castle nut, end plate, A5-style buffer, and a rifle-length or intermediate-length spring separately to complete the build.
No. This is an intermediate/A5-length tube, and it needs an A5-style buffer paired with a rifle-length or intermediate-length spring to cycle correctly. Standard carbine buffers and springs are not compatible with this geometry.
It refers to the drain holes machined into the tube that let water clear out quickly instead of sitting inside after exposure to rain, submersion, or heavy cleaning. It is a small feature but a useful one if your rifle sees wet conditions regularly.
More positions means finer control over your length of pull, which helps if you are switching between different types of gear, body armor, or shooting positions. It is especially useful for households or teams where more than one person shares the same rifle.
