As above regards the Lighting, they're shite. Rubbish build, crap triggers, useless moderator, the screws need constant tightening because they twang and rattle like feck, stupid odd sized scope rail, the barrels go slack in the jaws after a while 'cos the bloody things are made from not much better than pig iron and it's only held in with a stupid little pin, and last but by no means least it says BSA (BRITISH Small Arms!!!!) on them and the shitty things are made in Spain
All the others you mentioned are quality kit and it's down to personal preferance
