KRISS USA
Factory three-position telescoping folding stock for post-2017 Gen 2.1 Vectors, with dual QD sling mounts.
The KRISS Vector Gen 2.1 Ambidextrous Folding Stock is the factory answer for post-2017 Gen II Vectors. When KRISS revised the Vector upper in April 2017, it dropped the proprietary integrated hinge mount in favor of buffer-tube threading, which orphaned the older folding stock assembly. This is the stock built for that revised receiver.
Length of pull telescopes through three positions at 8.5, 9.5, and 10.5 inches, which is a wider spread than the Gen 3 stocks offer and enough range to work in a plate carrier or in shirtsleeves. The push-button hinge folds to either side, so you can clear whichever side your optic and support hand occupy. Sling attachment is the strongest part of the design: dual QD swivel sockets plus a rear loop, where the Gen 3 stocks give you neither.
Buy it only after confirming which Gen II you own. A pre-2017 Gen II has a visible integrated hinge mount at the rear of the upper and takes the KVA-FSBL00 assembly; a Gen 2.1 has buffer-tube threading and takes this. KRISS does not make an adapter to run the older hinged stock on a Gen 2.1.
Add the KRISS Vector Gen 2.1 Ambidextrous Folding Stock to your build and see how it enhances your platform.
