Dual purpose A.I. / E.T. Guns with 21" length available for 1/4cc or 1/2cc straws.
With A.I. / E.T. guns you will see the terms 'deep' or 'shallow' chamber. This designation refers to where the straw stops within the barrel of the gun. 'Deep' is for use with an uncut straw. 'Shallow' is for a straw where the seal must be cut off to open it, shorening the straw.
