Looks and feels good but I don’t like the 1913 hinge mechanism

by Eugene Moses Kalashnikov, Verified Owner from OH, United States Written on January 25, 2026
I got this because I have one of their older versions (from when they were “A3 Tactical”) on my Stribog and I liked the way it locked in the folded position. Sadly, this new version does not lock in the folded position, it just swings open which makes it pointless to attach a sling to it.

Also, the way the 1913 hinge attaches is a poor design in my opinion. Instead of a clamping design with a lug/crossbolt, you fill a 1913 slot with a tiny steel piece, slide the mount over the 1913 rail and tighten two tiny set screws (2mm hex) which pulls the mount away from the rail. My problem with this is the entire engagement relies on two tiny set screws for both vertical and horizontal forces. If you have to mortar your gun to clear a malfunction, you’re essentially hammering on the set screws and their tiny bit of thread engagement.

I still like the aesthetics, it works and is modular but I wouldn’t recommend it for serious use
Pros:
  • Modular
  • Aestetically pleasing
Cons:
  • No lockup when folded
  • Poorly designed 1913 interface
Best Used for:
  • Range
Would recommend: No

Well made folding stock

by maiti, Verified Owner from LA, United States Written on August 27, 2024
I really like the ability to tailor make my own A3 stock using the various components available. I would highly recommend visiting the A3 tactical website to get more detail idea of the components and their dimensions. The stock is solid with no wooble at all. I would recommend getting the cheek riser, which is much more comfortable than bare metal rail. The only negative I experienced is the height of the folding hinge. The hinge extends below the stock and in my case interfers with my grip, as it will hit my trigger hand. This maybe just for this particular rifle setup but it was a serious enough problem for me. I reached out to A3 about this and they were prompt in their reply. They suggested that I try reversing the hinge upside down. I think that will work for some rifle but not for bolt actions or side chargers as it will fold on right side and hit the charger/bolt.
Pros:
  • solid built
Cons:
  • None
Would recommend: Yes

A3 SIDE FOLDER

by Gunfighterman, Verified Owner from PA, United States Written on April 25, 2024
This A3 side folder is very stable, strong and compact when folded. I purchase it for my Scorpion Evo3 S2 micro SBR mainly to fit in a gray man sling pack for EDC.

Optics Planet had about the best selection and great prices around. Shipping was extremely quick too.
Pros:
  • stability, compact, strength
Cons:
  • None
