1944 GRI No.1 MKIII

[Alan de Enfield]

The bolts are not directly interchangeable, they certainly are not 'plug & play' & whilst it may 'fit and function', it needs 'FITTING' (as in work needed grinding etc) properly otherwise it could take all the recoil on one locking lug, which could lead to lug failure.

It is not impossible to 'fit' an old bolt into an old rifle but it does take some skill and knowledge.

In addition as MKVII said, there are all sorts of little bits & pieces that need tuning to get it to specification.
