RIS TwinFold Stock
Looking for a lightweight and durable folding stock that fits your RIS (1913) buffer interface and offers dual-side folding for compact transport and fast handling? Need a stock with a QD sling mounting point for quick attachment? Want compatibility with popular platforms such as MCX or STRIBOG? The CTM TAC TwinFold Stock is an innovative stock system for rifles using the RIS (M1913) mounting interface, fully compatible with adapters for AR15, AK, MP5, CZ EVO and other platforms including STRIBOG, SIG MCX and MPX. Thanks to the ambidextrous folding mechanism, the stock can be folded to the left or right side based on the user’s preference. The body is made from high-strength 6061 / 7075 aluminum, with four stainless-steel locking points ensuring maximum rigidity and durability. The stock features an integrated QD sling mount with an anti-rotation stop for secure attachment. Its skeleton design is also compatible with the M-LOK system, allowing the addition of accessories including alternate butt pads. If needed, the stock can be fully detached from its RIS base and the gun can be used without it.
