The M30 remington is a civilian version of the P14/M1917 Enfield. There are stylistic differences and some trigger changes. Still they are the same basic rifle...in civies! There were different 'grades' of model 30, including a carbine. The higher grade rifles bring a premium and all bring more if not altered(most were drilled for a scope mount.. The M30 Express is a really nice older rifle. The action is well made and quite strong, although it's gas handling properties are not the best(is a case or primer should leak). In reality this is rare and I would not be afraid of the weapon. I regularly use a 1917 Enfield(winchester built) converted to 300 WinMag to hunt with. It's not change zero in many years unless a change was mode to the load(major one at that). It took a doe saturday evening last and hopefully will take more as the season here progresses....
