Re: 1917 Enfield - Modify or leave as is?
There are, also, many "military bolt action rifle" matches held at local gun clubs/ranges throughout the country. Although, the model 1914/1917s were never known as 'tack drivers'. It takes some practice and a hand full of stripper clips to get the 10 shots off, accurately, in the rapid fire stages of the CMP Qualification shoots. A Winchester or Remington made 1917, in good or better condition and unaltered, has much more value than one might think.
"Shoots real good!": definition; it didn't blow-up in my face.
