A large European barrel maker is planning on making a run of No. 4 Barrels. These will be threaded and chambered. They will have 4 groove rifling and will also have the bayonet lugs machined as per the originals. Anybody interested can check out: Welcome to Lee-Enfield Rifles. The more barrels in the first run, the better the price. Anybody interested in replacement No 1 barrels should also let Brett know when you email him.
