Key areas covered include checking woodwork for looseness, understanding bolt removal variations between Mk 1 and Mk 1* models, inspecting critical components like the extractor and bolt head, and assessing barrel bedding and pressure. It emphasizes practical checks over cosmetic flaws for military surplus firearms.

Quick Summary

When buying a Lee-Enfield No.4, inspect woodwork for play, check bolt release mechanisms (Mk 1 button vs. Mk 1* rail gap), and examine the extractor and bolt head for wear. Proper barrel bedding should have 2-7 lbs of muzzle pressure, and ensure the barrel returns to center. Be mindful of headspace differences between British military (74 thou) and SAAMI (71 thou) standards.

Frequently Asked Questions

What are the key differences between Lee-Enfield No.4 Mk 1 and Mk 1* bolt release mechanisms?

The Mk 1 utilizes a push-button release for the bolt, whereas the Mk 1* commonly found in North American production employs a gap in the bolt rail. Inspecting this rail gap for wear is crucial on Mk 1* models.

How should I check the barrel bedding on a Lee-Enfield No.4 rifle?

Gently lift the barrel at the muzzle within the nose cap. Ideally, it should require 2-7 lbs of downward pressure. Ensure the barrel returns to a centered position after being pushed to confirm proper bedding.

What headspace standards should I be aware of when buying a Lee-Enfield No.4?

The British military standard for headspace is 74 thou. Be aware that modern SAAMI standards (71 thou) can be overly strict for these surplus rifles, potentially leading to misdiagnosis of issues.

What common mistakes should I avoid when inspecting a Lee-Enfield No.4?

Avoid focusing solely on cosmetic flaws like stock cracks. Prioritize functional checks such as woodwork play, bolt head overtravel (worn threads), and proper barrel bedding. Also, don't assume SAAMI headspace gauges are the definitive test for these older rifles.
