These modern versions rely on the classic straight pull bolt action design to chamber each cartridge fed from a 10 round rotary box Double Helix magazine. The T-Bolts three-lever trigger offers a light, crisp break, and every barrel is free floating. Those of you who are serious about rimfire accuracy will appreciate the T-Bolt Target/Varmint model. It features a walnut stock with raised Monte Carlo comb and a heavy varmint barrel designed to provide pinpoint accuracy that rivals many custom rimfires costing much more.
