Perhaps the mechanical design and loose fit is a lot better than the robustness of it.
I have to agree is robust enough but it is not robust when compared to other rifles of the times
when we look at the breach and locking design. It can be perhaps a tad faster (Subjective) but it
is not the best design on paper nor in real life. The mauser for example is a smoother and better bolt.
I'm not an Enfield fan myself, nor really a fan of any vintage bolt action because of the ergonomics. But, I think it's cool that it was still wrapped up like that and in really nice condition. Other than that I know nothing of them lol.
Now if I found an old AK like that
The main issue is that is a rear locking action that are weaker by design. On top the extractor is the very same receiver
that is dragging the ream along until it tilts. So that contributes to the drag effect.
But again these guns lasted so long and then had to be serviced. Still good guns but not what I would call robust.
Even a mosin is more robust because it locks at teh front with a lot more bearing and less torque.
But when we compare this to lets say an springfield or mauser it looks like a toy action.
Rear locking is self limiting by design and the only way to make it stronger is by making them
a lot more larger and heavier. That is why the barrel extension was the greatest addtiion to
firearms aside from smokeless powder, detachable magazines and a hand full of innovations.
All the torque is self contained at the breech and can be made stronger w/o putting torque
forces in the rest of the group.
Not only that but the whole action is a lo easier to service and index / headspace.
The only rifle of this era I've ever owned was my K96 Mauser. Shot great but I just couldn't get past the stock and let it go. If they had some of the drop in custom stocks that they have now I probably would have kept it.
Well, actually had a Jap Carcano, but that was only bought to resell. Didn't like that one either lol.
