Nathan FosterHi Cor. OK, lets see.
As Thomas says, the bores on these are mostly done now. Even if the bore looks good, if the rifle was used for culling etc, the throat may be cracked and it is important to understand that eventually, the barrels do rupture at the chamber. But this involves a very high round count- culling / cadet training etc. You'll need to check the muzzle and what you can see of the bore up close as Warwick did with his BSA CF2 in the other thread. Check the throat as best you can.
Putting a suppressor on an enfield? The barrel is quite thin on the Mk111, check to see how far the barrel was turned down for thread cutting. An M12 thread is too thin for your local temperatures. Heat trapping within the bore is also an issue (you are up at 40C lately?). Barrel corrosion is an issue during wetter seasons / evening dew etc. Corrosion of the suppressor is also a major issue if the last owner had access to cordite loads.
The plastic stocks have a better ergonomic feel but are far from stable. The fore stock would need bedding work etc to enhance accuracy potential. I prefer to inlet a pistol grip and fit a small comb into the original wood but many people do prefer the look and feel of the synthetic.
Study the scope mounts if it has them. Some are quite badly aligned and have odd ball bases. This needs to be checked on all old military bolt actions including the Mausers. Make sure no screw holes interfere with lug rebates on all ex military bolt guns (have to go by eyeometer in your case sorry)
The trigger will of course be quite heavy. Many of us including myself cut our teeth on this rifle but if the person has very limited experience or does not have the help of an experienced shooter, the person can pick up bad trigger habits and bad over all habits. Here again we see the need for a system of full control as per my last book.
Head space as Thomas said is an issue. Check fired brass to make sure it is not stretched to the point of breaking. The best DIY check would be to cut a case lengthways but this is typically beyond the scope of a basic buyer check. You can at least try to look at used cases and look for a bump and shiny mark.
Make sure it is tested at 100 yards, not 25 yards etc. Some of the old rifles go OK at 25 yards but then scatter shots out at 100 yards of more with yaw.
Generally speaking, BSA made a nice rifle. But these are getting on now. Very dicey business as far as the bore goes.
