I'm trying to sort out my weapon light just now, and not arriving at any good answers.
I have some that wear wood, and look more like its the 1950s. The thing is they are functionally inferior. I appreciate a simple AK for what it is. I'm also not a fan of tacking stuff on a gun just because. However, carefully thought out additions can really be a functional improvement. Turns out people have come up with a few useful enhancements in the last 60+ years. Pistols in the last hundred years on the other hand (or were you talking about the plate carrier, or the sweet bedding ) Actually I like my 1911s for what they are, but own a number of wonder 9s as well. I've gotten to a point recently where I am much less concerned about hardware than I am the ability to use what I have well. Again well thought out additions and modifications can help serve that end goal though.
