We give examples of countable linear groups Γ < SL3(R), with no nontrivial normal abelian subgroups, that admit a faithful sharply 2-transitive action on a set. Without the linearity assumption, such groups were recently constructed by Rips, Segev, and Tent in [J. Eur. Math. Soc. 19 (2017), pp. 2895–2910]. Our examples are of permutational characteristic 2, in the sense that involutions do not fix a point in the 2-transitive action.
