What scopes and rings will fit the Lux and Special?
It depends. Scopes shorter than 12" will fit neatly behind the rear sight base with little problem. You must remove the rear sight to do this. Scopes in the 15 inch range will often fit nicely with the objective bell in front of the rear sight base. In that case you can leave the rear sight in place.
The biggest problems are with bulgy scopes (big 40-50mm objectives and adjustable objectives in particular) and scopes in the 13-14" range. The best example of this is the Bushnell Sportsman 4-12x40AO available at your local Wal-Mart or Kmart. These scopes require a lot of height to clear the rear sight base. I overcame it with Tasco tip-off to Weaver-style adapters and Millett medium rings. This combination puts the scope almost 0.9" above the receiver and clears the rear sight base. This may be uncomfortable for some but is an advantage if you are shooting silhouette or Sporterifle from an offhand position.
The BKL and CZ rings are fairly high and have been used to mount a variety of scopes. I have use the BKL 257s to mount a Simmons 1048 6.5-20x44AO with the objective bell in front of the rear sight base. The Beeman 5030H rings should mount just about anything under 50 mm with their 0.75" height. The Millett High CZ/BRNO rings are in between and should also mount a wide variety of scopes.
I am developing an 11mm to Weaver adapter that will provide about 0.5" above the receiver and will take any of the wide variety of Weaver style rings. With this as a starting point you should be able to find appropriate rings to mount any scope.

Miras en la seccion FAQs y ahi tienes todo el tema de los visores para la 452 bastante bien explicado.
En resumen es que si tu visor mide mas de 14, 6 pulgadas de largo y campana de 50mm no tendras problemas para montarlo sin que te toque el alza si usas unas monturas altas.
Mi visor mide esas 14,5 pulgadas de largo con campana de 40mm y le he puesto unas monturas altas y me sobran 8 mm hasta tocar el alza, estoy buscando unas monturas medianas (3/4 de pulgada) regulables en elevacion para dejarla perfecta, porque a 50 mts tengo que darla 14 moas de elevacion, pero a 100 mts necesito toda la elevacion que da el visor para ponerla a cero con municion Eley verde:8.
Pues yo te estaria muy agradecido si pones el enlace de donde has tocado el tema, ya que yo tambien tengo ese problema y estaba barajando la posibilidad de quitarle el alza.
Asi de que monturas le habeis puesto para vuestras carabinas.
