The TRG M10 has a side-folding and fully adjustable buttstock, featuring an aluminium middle chassis frame, side-folding buttstock, and a fore-end with the M-LOK rail interface system that allows for direct accessory attachment onto "negative space" (hollow slot) mounting points, ambidextrous controls, a manual safety that is located inside the trigger guard which is in front of the trigger, and uniquely designed tactical indicators which helps identify different modular components for different calibres, where every calibre-depending component is specially marked so users can recognise the calibre of each part visually or by touch. For example, for the .308 Winchester barrel and bolt are marked with single annual grove, whereas for the .300 Winchester Magnum are marked with two groves and three for the .338 Lapua Magnum. Another unique feature of the rifle is that all of the tools that are necessary to change the calibre are built into each of the bolt handle; the small torx key is built into the centre of the bolt knob and the barrel wrench is integrated into the base of the bolt handle. An additional set of Torx keys are stored inside a small detachable polymer forend, which are necessary for full disassembly of the gun.
