Telescoping Magazine Tube Adjustment Spacer

Internal spacer for Briley Telescoping Magazine Tubes. One spacer is included with all Briley Telescoping Magazine extensions - this is an additional spacer to fine tune the extended length of the magazine extension for overall length or capacity requirements. Magazines are shipped in a 12-round configuration for most guns. The spacer can be used whole or trimmed in 1/4" increments for length adjustment.

Typically, factory configuration Benelli M2s and Beretta 1301s need 2 - 3 sections from an extra spacer to fit the IPSC 1320mm length requirement, however changes in stock dimensions will affect the overall length. More information can be found in our Disassembly and Cleaning Instruction Video.
