Was this made for an airsoft? by Tinman1965, Verified Owner, January 1, 2025

Perfect option for your pistol by Guy in Pequea, Verified Owner, April 3, 2026
Strike Industries FSA Single Folder Stock fits perfectly on my HK416 pistol. I purchased a 1913 rail adapter separately and the combination is absolutely rock solid. The spring that is part of the stock is a bit stiff and takes quite an effort to f...

Sturdy & Looks great by Lewis1911, Verified Owner, April 1, 2026
Chose this stock for an MPX SBR project and worked-out perfectly. I have purchased my share of "minimalist" style folders, and many are not that solis. This thing locks in tight, with no movement and has a great look to it.

Product Info for Strike Industries FSA Single Folder Rifle Stock

This is the new Strike Single Folder - Stock Edition.image

You may already be familiar with our Strike FSA Dual, a modular folding arm solution that can fold to the left and the right with interchangeable stock and stabilizer end pieces. While the new Stock Single Folder still utilizes the same arm and stock end piece as our Dual Folder it has a strengthened hinge made of steel, instead of aluminum, making it extremely robust. The fitment is also perfect with little to no play when extended and folded. This folder only folds to a single side but can do so at any time without reconfiguring or using a button.

When the hinge is installed to fold left, users will experience similar muscle memory if they've already used our Dual Folder - the action is the same to fold. Simply lift up on the arm and fold to the left. In its folded position, the arm can be forcefully thrown back into the extended position for quick deployment with no risk of damage to the hinge thanks to its new beefed up design. At the 3 and 9 o'clock positions there are two QD points located on the stock end piece for attaching your favorite sling. Since you're running the Stock edition of our Single folder, be sure to pick up our adjustable FSA Cheek Riser for this as well to make your shooting experience more comfortable.

The Strike Single Folding Adapter is compatible with any weapon platform that has a rear-facing 1913 Picatinny rail. To attach, tighten the hex screw in the hinge adapter onto a pic rail. Look no further for a compact, lightweight, and reliable single folder! (On its own, the Single folder is 11oz. With a Cheek Riser it weighs 12.41oz)

Whether it's for our SMC Bravo Chassis, a pistol caliber carbine like the CZ Scorpion, or a PDW style AR-15, the Strike Single Folder is perfect for them all. Get yours today!
