Garrett, I was joking about the ee cummings, but yes I like the #5. I'm also with you on iron sighs. The most sophisticated rifle I own is a pair of Winchester 94s. Here's why I agree with you about the Enfield:
1) It's pretty. It's balanced, and it just looks right. Any engineer can tell you anything that does that, and works, is a work of art.
2) The jungle carbine variant may not hit out to 300 yards, but so what? I noticed the word "jungle" in the name, so that's not part of my expectations about a carbine.
3) It's historic. Very historic.
The .303 Enfield #5 shares a lineage with all Enfields, and make no doubt about it, they saved the allies in WWI. Without the Enfield and the hard, disciplined troops of the regular British forces in the first weeks of WWI, there would possibly have been no Allied victory in that war. It was the smooth action, quick magazine, and good accuracy that let a small but professional group of British soldiers slow down the right wing of the German forces enough to stave off defeat of the French armies in the early days. No other rifle of the time could have let them do what they did, and it's one of the most historic rifles of all time. The Garand alone did not win WWII for the Allies. The Brown Bess, the Mauser K98, the Ak47, the Springfield Musket - no argument exists that any alone was a "war winning" weapon. But an intelligent, documented, and sensible argument can be made the BEF's use of the Enfield in the fall of 1914 prevented defeat in WWI.
There's an adage I read once by a very knowledgeable firearms historian who said, in regard to WWI - "The Germans brought a hunting rifle. The Americans brought a target rifle. The British brought a battle rifle." The more you study the arms of WWI and WWI, the more you realize how true and pithy that statement is.
And if what you like is the later jungle carbine, so be it. I love the Enfield for the history above. After his death, a teary Churchill said of F.D. Roosevelt, "He saved the world." I think an intelligent argument can be made of the Enfield stating the same. And there is no other personal weapon I think you can say that about.
