What’s Included
- Rossi Rio Grande RG4570 Large-Loop .45-70 Govt. lever-action rifle
This RG4570 is the large-loop variant, offering easier manipulation when wearing gloves and adding a distinctive appearance. The action is the same smooth, solid-lock design Rossi is known for, now paired with an oversized lever that enhances control.
The 20-inch alloy-steel barrel features a 1:20 right-hand twist that stabilizes a wide range of .45-70 loads. A ramped, hooded front post and an adjustable semi-buckhorn rear sight give a clear sight picture out of the box, while the drilled-and-tapped receiver lets you add a scope or rail without gunsmithing.
Brazilian hardwood stocks with a satin finish provide a comfortable 14-inch length of pull. The pistol-grip profile, ventilated recoil pad, and sling-swivel studs contribute to practical field handling and recoil management with heavy .45-70 cartridges.
Safety is handled by a cross-bolt safety, a half-cock hammer notch, and the Taurus Security System keyed lock integrated into the hammer. Together, these features deliver multiple layers of security without compromising the traditional lever-gun feel.
