S&W 15-22 +7 Magazine Extension / Bumper (10rd Magazines)

• +7rd extension gives you 17rds total
• Highly durable and lightweight polymer
• Base and follower kit
• +6 extensions for 25 round magazines available here

Easily increase your Smith & Wesson M&P 15-22 10-round magazine from 10 rounds to 17 rounds with our +7 extension base. This enables you to maximise the rounds in the magazine while still being low-profile enough to go prone.

The minimal added length is enough to get in and out of a magwell comfortably, while the extra weight encourages it to drop free when released. High durability and low friction polymer construction.

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 found here.

Note: Magazine not included
