Specifications

  • Weight: 1.25 lb
  • Mount type: 1913 Picatinny
  • Country of origin: USA

Product Description

Build a folding stock configured for your firearm and shooting preferences. The Modular Folding Stock mounts directly to a rear MIL-SPEC 1913 Picatinny rail and offers multiple extension lengths, offsets, buttplates, and accessory options.

Key Features

  • Sure-Lok™ folding hinge with push-button release and quick deployment
  • Reversible hinge for left- or right-side folding
  • Locks securely in both the folded and deployed positions
  • Six extension options: straight or offset in three lengths
  • Four buttplate options
  • Full-length M-LOK slots for sling mounts and accessories
  • Optional Xeno Modular Cheek Rest
  • Made in the USA

Choose Your Extension

Straight extensions position the stock directly behind the hinge.

Offset extensions provide 1.25 inches of offset and can be installed in four positions. This allows you to:

  • Clear charging handles, ejection ports, and other controls
  • Adjust cheek height for different optics
  • Position the buttplate higher or lower for comfort

Overall Length

Extension lengths refer only to the aluminum extension arm. The hinge and selected buttplate will add to the stock’s overall length. Refer to the measurements below to determine overall length.

6.50" Extension

  • A3T Buttplate: 8.00"
  • Magpul #1 or #2 Buttplate: 8.75"
  • XTENDO Buttplate: 9.75"

7.50" Extension

  • A3T Buttplate: 9.00"
  • Magpul #1 or #2 Buttplate: 9.75"
  • XTENDO Buttplate: 10.75"

8.50" Extension

  • A3T Buttplate: 10.00"
  • Magpul #1 or #2 Buttplate: 10.75"
  • XTENDO Buttplate: 11.75"

The fixed non-folding mount reduces each overall length by 0.50".

Sure-Lok™ Folding Hinge

The patent-pending Sure-Lok™ hinge is manufactured from 17-4 stainless steel using the metal injection molding process and finished with QPQ treatment for strength, wear resistance, and corrosion protection.

Press the button for controlled folding or pull firmly on the stock for quick deployment into the locked position. The hinge can be configured to fold left or right and mounts securely to a 1913 Picatinny rail.

M-LOK Accessory Mounting

Every extension arm includes full-length M-LOK slots. These can be used to position a QD sling mount or other compatible M-LOK accessories anywhere along the extension.

Optional Xeno Cheek Rest

The M-LOK-mounted Xeno Modular Cheek Rest is configurable to three heights.

  • 5/8 inch
  • 7/8 inch
  • 1-1/8 inches

Its reversible design also allows the cheek rest to be positioned one inch to either side of the mounting point.

The extension arms and buttplates are machined from aluminum and finished with a low-gloss black anodizing. Made in the USA.

Bets folding stock on the market

not only does this brace have excellent fit, finish, and choice of profile and length, but it actually has buttpad options with a normal stock profile (I chose the magpul, I hate thin stock pads) and a comfortable cheek riser (I find most competing brands offer risers with very hard edges). Can't recommend A3 enough!

Excellent Product

With the setup I have on my SBR the regular straight back stock did not give me the eye box I needed. I had several stocks from previous builds that I tried. I needed to get the tail hook of the stock lower without lowering the cheek weld part of the stock. I searched for a offset stock. After viewing several options I liked the A3 Industries offerings. Their modular system lets you customize your stock to fit your exact needs. I was a little skeptical about their picatinny hinge locking system. I was used to clamp type of system with lots of contact and tight locking with multiple bolts. I was blow away after I installed the stock and tightened it down. The product is very well built and very modular offering many options to fit the need of the end user and firearm. As an engineer with many patents I was impressed with the design. As a former army operator I am always looking for any accessories that can stand up to the rough handling that is the mainstay of a reliable military system. Whether you are a professional end user or a holiday sportsman you will be very satisfied with the products from A3 Industries.

Very awesome stock and, "it totally doesn't work with a kriss vector". The 1913 pictanny adapter works well and the xeno cheek riser doesn't do much. But other than that it's bad ass.

Exactly what I was looking for. !

I spent quite a bit of time looking for a foldable stock that would check all the boxes. This deploys easily, folds very compact so it fits my case and is very lite. Not to mention it looks great!

Modular folding stock

Great product, only complaint is there’s a small amount of play in the hinge.

This butt stock is worth the tax stamp.

Fitment is spot on and I guessed at length of pull when selecting. It made my build look legit.

Purchased for Kriss Vector

I do love this brace but the shipping was incredibly awful. Paid for 3 day and somehow USPS lost the package for over a week. Not A3’s fault. 4 star because the brace had a small knick in it where you can feel a sharp burr and finish missing. Would’ve contacted but after the crazy shipping stuff I’m over it.

Nice stock for the price

Really please with the product and quality. Loved the customization options of the stock. I'm still trying to figure out how to change the folding side. Have yet to test it at the range.

Great stock !!!!!!

Amazing stock !! Locks up tight doesn’t wiggle at all. I got the leverage adapter and it’s a little hard to lift up but I’m sure it will get easier. It was worth every penny and a great feeling stock plus look at it !!!!

Offset stock

Got the offset, first it just looks great.
It is very functional with the cheek riser feels great. I love this stock and will buy it again when I get another rifle that would use it. This is installed on a BRN-180. The folding mechanism is solid and works great. Happy

Excellent product

I purchased one and liked the way it fit, so I purchased another one the same week.

Awesome stock

I love this stock. Perfect fit for an AKV. Folds with a push button instead of having to pull up on it. I have several other folders from different manufacturers, and that’s my one complaint with those. This one you just push the button and it folds. Cheek riser can be moved along the stock to get the perfect cheek weld. Stock is very well made, and feels sturdy.

Good

Overall I like the product. Has issues folding in the beginning. It is getting better but still pretty tuff to fold either direction. Because of the location I wanted my qd sling attachment, the cheek pad doesn't work. Overall a good product.

AR7 with some modern flare

So I bought a henry survival rifle a while back and decided I wanted to modernize it. Being kind of a niche firearm in the first place I knew finding parts would be difficult. The fit and finish of this is spectacular. I still, personally think the price point is a little steep but, you get what you pay for 100% would recommend this product

Fit and Finish

Bought the offset extension butt pad and sig hinge for my MPX SBR build. The amount of off set is perfect for eye alignment with the attached Holosun red dot. The fit and finish of the hinge and extension are perfect. Highly recommend.

A3 Tactical Improving My Scorpion

This SKELESTOCKS is a really good piece of hardware. Running with the 1913 pica it runs with a very smooth ease of use on my scorpion. Going to the higher cheek riser (on order). Loving it. But waiting on the 1913 MTS for this CZ. Hoping that it is not a long wait.
