Hi 7point82,

The Lee Enfield No4 Mk 1 (T) with the 3.5x scope was actually regarded as a sniping rifle. The rechambered 7.62mm NATO round offered very little improvement over the 0.303 round especially compared to the Mk8 ammunition.

A number of No4s were converted to 7.62 NATO (Enfield L39A1, L42A1 )and became the standard sniper rifle, which was still in use well into the mid eighties. There was very little difference in terms of performance between the Enfield No4 Mk1 (T) and the L39A1, L42A1.

The L39A1 and L42A1s were replaced with the L96A1 (L96) in the mid eighties giving a somewhat marginal improvement in accuracy. The L96A1 can shoot less than 2" (51mm) groups at the distances of 600 yards (550m) or greater than 0.5 MOA using boat-tail match ammunition.
