Barrel Plug

Sub-Caliber

This is high-durability, wide temperature Silicone that tapers from 1/8 in (3.18mm) to 1/32 in (.79mm)

Use? Well, any hole or port other than one of the two main barrel openings that would cause leakage of liquid into the barrel. This is a common item for systems with gas ports smaller than .125 inches is diameter - for example M1 Garand, UZI, and any that don't need the next size up or larger. Useful for any acid hot or cold, and hot bluing.

Temperature range is from 0 degrees F to 600 degrees F (316 C)

At 5/8 inch long, it is big enough to handle.

Each of these plugs will survive multiple uses with good care.
