This enables shooters to make use of Rem seven-hundred triggers, stocks, and bases, most of which might mimic their centerfire rifle setups. Shooters can even use most of the exact scopes and mounts as the optic set up is Rem seven hundred compatible.  The stock is exactly what most distinguishes the T3x UPR from other models inside the T3x line.
