Worldwide shipping calculated at checkout!

Easily increase your stock Smith & Wesson M&P 15-22 10 round magazine from 10 rounds to 17 rounds. This enables you to maximise the rounds in the magazine whilst still being low profile enough to go prone.

The minimal added length is enough to get in comfortably in and out of a magwell, whilst the extra weight encourages it to drop free when ejected.

Made out of our special high durability and low friction polymer these competition components are made to give you an edge.

It is recommended to use an external load assist device with this kit as the original load assist button is no longer used.

Note: Compatible with 10 round 15-22 magazine only, 25 round extensions can be round here.
