Product Description

  • 10 Shot Extension Tube (10 shot total capacity)

This extension allows you to increase the ammunition capacity of the shotgun to 10 rounds. The extension is made of tough 6061 aluminum. This allows the tube to have a large wall thickness to improve rigidity without compromising overall weight. The tube screws down on the magazine and locks the fore end in place. The extension is supplied with a spring. 

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

  • 10 Shot Extension Tube with Picatinny Rail (10 shot total capacity)

This is the same sturdy Briley magazine extension made to accept a dual Picatinny rail. The fore end lock has been shortened to bring the Picatinny closer to the fore end. When using a light it will allow the switch to be as close to the receiver as necessary. The fore end is locked down, the spring is inserted in the original magazine and then the extension with the Picatinny is place over the spring and screwed onto the forend lock. Before tightening the tube to the fore end lock you orientate the Picatinny, either bottom left or bottom right. Tightening the tube to the fore end lock will also capture the Picatinny rail. Hang you favorite light or laser on it or both at the same time. Package includes the follower and 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. Excellent! 5 Star Review

    Posted by on 23rd May 2016

    I bought the 8shot (+3) extension tube, but can actually get 10 2-3/4 shots in it, when spring is cut at optimal length (no info in the package about that though, trail & error is advised) I cut about 4" to get it right!
    The quality is superb and it fits like a glove! I wish I had som more info before I purchased it, because it's about 2.5-3" short of the barrel now and I would've liked it to be flush, but that is not a real issue since you can add a +1or2 module later!
    Highly recommended if you'd like a tactical twist to your A400 Xtreme! You won't be disappointed, the hardest part was to remove the original magazine tube(mine was crimped to hold 2+1) from the action and fit a new uncrimped one, once that was done fitting took about 2 minutes!
    Grace shipped with lightning speed to Scandinavia!


  2. Beretta A400 Extreme 5 Star Review

    Posted by on 22nd Dec 2015

    I received the Briley mag extension and was very happy with the quality. Getting the spring unraveled was the longest process and that wasn't bad. It took 3 minutes for me to install it. The shipping was fast and the notifications were great.


  3. Awesome & Quality Product - Beretta Magazine Extension 5 Star Review

    Posted by on 1st Apr 2015

    Bought the magazine extension in matte black for my Beretta A400 Extreme Unico (Optifade camo). It not only looks bad to the bone, but matches the partly black finish on the gun's fore-end perfectly. It installs seamlessly after taking the plug out & replacing the factory coil w/ the one Briley includes, and functions even better! It cycles all 11 (10+1) shells like a dream - time after time.

    Very FAST SHIPPING by Grace Shooting Parts.

    Highly recommended!

    GOD BLESS!


  4. Awesome product but no barrel clamp 5 Star Review

    Posted by on 26th Oct 2014

    Awesome product and in my opinion the best built extension I've seen thus far. but for the price i expected to get a barrel clamp which was not included and you do need one it won't stay strait without one

    FYI i put this on a tristar shotgun with some light modifications


  5. Great Product 4 Star Review

    Posted by on 10th Feb 2014

    I purchased the +5 (10 total) round extension for my Xtrema 2 and am very pleased with the fit and function. The threads were all nicely cut and it fit perfectly. It runs very well. Also a kudos to Grace Shooting Parts for their speedy delivery of the product.
