Briley now offers a new magazine extension that allows the gun to be used with either 8 or 10 shots. It is essentially an 8 shot extension with a short coupling that extends it to 10 shots. One simply removes the end cap off of the 8 shot tube, fits the short extension to it and then screws the end cap to the short extension. The unit is supplied with a barrel clamp which we recommend you clamp to the extension at the joint area when using the 10 shot extension. When using the 8 shot extensions remove the clamp completely or move it further back.

Tube and clamp are both made from 6061 aluminum and black anodized. The barrel clamp will also allow the attachment of a sling swivel.

Although we keep a small inventory of polished units, it may take as long as 3-4 weeks for delivery of any polished mag extension.

Custom shortening of a magazine tube to a specific length is an additional $35.

Please note: magazine extension tubes are a regulated commodity by the U.S. Department of Commerce, and are not exportable to all countries. Briley Mfg will notify you should this regulation affect your order.

Please note: due to the varying lengths of factory magazines on each gun, you may be able to insert more rounds than specified. Please make sure you are abiding by your state’s applicable laws.
