Probably the best folding brace! by Moe, Verified Owner, May 22, 2025
First it feels well made very sturdy, made of aluminum not plastic. I love that it can fold either side. I have it mounted to my Ruger PC Charger, it complements it well. It is an excellent value.

This stabilizer is awesome, I recommend the double sided folding stock mainly because when extended it has a double locking system that doesn’t let it close on you at the range. The single fold lack the extra lock. It also allows you to easily replac...

This is noice! by Noice, Verified Owner, April 29, 2026
There’s not much to say about this. It’s a great brace and if you inadvertently put it into your shoulder, it’s still comfortable. I guess the only thing that I wish it had was a slot that I could more easily put a strap through to secure it to my fo...

Nice folding stock by Brett, Verified Owner, March 18, 2026
I bought this for my Rossi in 300blk and it's perfect. You do need a pistol grip with an adapter, but man, it's nice. Also, if you plan to use the brace, use the rubber shims that come with it. They completely get rid of the wobble.

World Excellent by McNuggety, Verified Owner, September 5, 2025
Put this on my Ruger Charger and am loving it, super comfortable and very sturdy. Some slight play when folded but nothing bad, stiff as a board when locked out

Product Info for Strike Industries Dual Folding Adapter Stabilizing Brace

The Strike FSA Dual Folding Adapter - Stabilizer Edition is a versatile and innovative patented system that offers unparalleled convenience and flexibility. With its intuitive folding mechanism, you can fold the adapter to either the left or right side of your weapon platform. Without the need to reconfigure or reinstall any parts, the provided locking mechanism has a positive lock and ensures its ability to stay in place.image

Deployment is quick and effortless with just a simple upward pull on the bar near the hinge. Its 3-degree tilt angle is designed to help prevent interference with your weapon's ejection port when folded to the right as well. This adapter fits directly onto a 1913 Picatinny interface with built-in locking lucks for secure attachment.

The included Stabilizer end is a great ergonomic option for completing your pistol build. Strike's Dual FSA's name comes from its interchangeability to swap out the Stabilizer end to a Stock end, should you desire to have a Short Barrel Rifle, (or SBR) configuration.

A simple pull up on the bar near the hinge and back for quick deployment when folded. A 3-degree down tilt angle is added to help prevent interference with the weapons ejection port when folded to the right side. The Strike Dual Folding Adapter mounts directly to a 1913 Picatinny interface with two (x2) built-in locking lugs for a secure attachment. For the stock rear piece, included is a rear rubber anti-slip buttpad to create the best possible shoulder weld for rifle or registered Short-Barrel Rifle (SBR) setups.

A single QD point is located on the rear of the stabilizer and ambidextrous QD sling mounting points for the stock. The Strike Dual Folding Adapter is constructed with a steel hinge and 6061-T6 Aluminum base, adapter & strut. Get a unique modular system with interchangeable (sold separately) parts like optional cheek riser (to be only used legally with stock setup), strut lengths and other accessories.

Use with almost any 1913 Picatinny rear end like the Strike AR Picatinny Stock Adapter or many factory OEM weapons with a Picatinny rail section in place of the traditional AR buffer tube threads. The Strike Dual Folding Adapter is a one of a kind adapter that gives you more options than anything on the market for those who want a truly modular folder that is under 10 ounces.
