Direct replacement barrel for the Lee Enfield No.4 rifle. Criterion replacement barrels are machined to the original contour with a milled front sight and bayonet lug. The No.4 is chambered in .303 British with a 1-10 LH twist rate. Built from gun barrel quality 4150 CM with a parkerized or “in the white” finish, No.4 replacement barrels come standard with a .010 short chamber and will require finish reaming. All existing models are available in the original military contour.

I want to thank Criterion for producing a great product with outstanding customer service. I installed a CBI barrel recently on my Long Branch No. 4 and discovered I had a defective chamber reamer. The barrel would just not shoot with a throat so long, and the MPI had shifted dramatically. CBI sent me a replacement at no charge. Well, this second barrel shoots! After break-in, it shot X’s at 200 yards. I shot it in the 2024 Talladega Spring Classic, first three sighters out of a clean cold bore were in the X ring. Anything not in the X ring is on me. I placed 3rd with a gold medal score even though my standing stage sucked (badly out of practice with the “wood guns”.). The No. 4 shoots every bit as good, if not better, than it did with the BSA barrel that was on it when it was new. I’m looking forward to buying a few more of these barrels once they are available.
