Our extended base pads are legal for USPSA Limited and Open competitions. Attached to the factory magazines they extend the magazine to 141.25mm length (5.56"). Whether you want to be competitive or not, these pads will extend the capacity of your magazines. Some of these base pads are best matched with Grams Format Follower and Spring Kit which additionally increases the capacity. 

Order on this page if you ONLY want the magazine extension! Design for each gun model is different and typically only fits that gun model. If you have any questions, please call us (720) 325 7890.

Recent Reviews Rating: Reviewed By: JIm B. Review Date: 5/19/2017 Comments: This product is second to none. It is a very high quality aluminum base pad. The fit and finish is awesome along with the customer service. I would not hesitate to purchase products from the Henning Group again. Not to mention that they got it out quick...
