The extension is supplied with a spring. 

Total length measures 13 1/2 inches.  For 12 gauge only.

  • 8 or 10 shot Magazine Extension
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.

  1. Very nice product 5 Star Review

    Posted by on 10th Apr 2016

    Very nice product. Quality craftsmanship.
    Looks very professional once installed and functioned perfectly.
    My only knock would be instructions could have been a little better. Even just a picture of how the finished product looks fully assembled.
    I also highly recommend getting the extension barrel clamp. Especially if you intend to attach a sling to it.
    Excellent customer service too!


  2. Good Service 5 Star Review

    Posted by on 6th Mar 2016

    I haven't used the product yet, but looks to be quality and fits my Winchester SX3 without any modification. FYI, 10 shot tube seems to thread on very sturdy without the need for a clamp. I purchased the clamp and will use it, but you could probably get by without it.

    Service was great. I ordered the 6 shot tube thinking it was a +6. Called Grace Shooting parts and they were very willing to help me. They changed my order to a 10 shot before it shipped and didn't even adjust the price to the more expensive 10 shot tube. I also received my tube in just a couple days. Very helpful. I would purchase from them again.
