A folding skeleton type buttstock designed for right- and left-handed shooters is also available. The folding stock is heavier than the non-folding green, desert tan or dark earth stock variants and is hinged behind the pistol grip; it folds to the left side and locks into position. When folded, the rifle becomes shorter. The steel parts of the folding stock are manganese phosphatised and the polyurethane parts are coloured olive drab or desert tan. The rear of the buttstock is adjustable for length of pull and height. The cheek-piece and rear support are also adjustable for height. These adjustment options allow shooters of various sizes and shapes to tailor the TRG folding stock to their personal preferences, which is an uncommon feature for folding stocks. The pistol grip body has a steel loop for a hook type military sling swivel. Sako TRG folding stock rifles are supplied with a Picatinny rail for mounting aiming optics.
