Historical and tactical overview

This circa 1952 bolt-action modification was purpose-built as a grenade-firing rifle. Reinforcements such as wire wrapping on the stock and the “GF” receiver marking identify its role in launching grenades with a blank cartridge. That conversion extended the effective range of infantry explosives while retaining the Lee-Enfield’s famed reliability.

Key features and condition

Grenade-firing modifications

The wire-wrapped stock and GF-marked receiver are not cosmetic—these are structural changes that allowed safe firing of grenade rounds. For collectors and operators evaluating a historical piece, those original marks increase provenance and operational authenticity.

Survivability and finish

The rifle spent part of its life preserved in oil, which darkened the wood. The seller notes the condition is better than photos convey and that the wood can be cleaned with solvent or seed oil if a lighter finish is preferred. Asking price is $1,399.99, reflecting rarity and modification history.

Ballistics: .303 British context

Although the listing identifies the rifle as shooting .303 British rather than providing a modern caliber label, the .303 remains a capable round for historical shooting, long-range marksmanship, and vintage ammunition enthusiasts. Ballistics offer good penetration and terminal performance at typical mid-range target distances consistent with bolt-action platforms.

Value considerations for buyers

When assessing this bolt-action piece, prioritize the grenade-firing markings, bore condition, and mechanical function of the bolt and sights. Given the conversion and era, this rifle is as much a piece of military history as it is a functional firearm—suitable for collectors, historical shooters, and demonstrators.
