Barrel Plug

Small Caliber

This is high-durability, wide temperature Silicone that tapers from 1/8 in (3.18mm) up just barely through .223 (5.5mm)

However, as a plug, it is only useful in the bore of a .17 Caliber: The chamber will have to be the next size up for rimfire, even larger for centerfire.

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

At 3/4 inch long, it is long enough to fit rifles, yet short enough for even 2 inch handgun barrels.

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