Totally random question that I'm sure the people of this lovely thread can answer... How much has gun design changed in the last 26 years? Or even just the last 16 years? Are new guns released today noticeably different to guns made at the start of the century, or is it one of those technologies that was essentially "solved" a while ago? Just curious as someone who only really has personal experience with antique guns (19th-early 20th century) what the 'modern gun scene' is like.
-Most Firearms today use mechanisms and actions designed and invented before 1950
-The AR-15 (more specifically the rifle that would thought slight modification become the AR-15 we know today) was made in 1959, the AR-10 even earlier
-The Glock, the first successful polymer framed pistol, was accepted into Austrian military service in 1982, and came to America in 1986
-95% of Bolt action rifles are essentially upgraded and or modified Mauser actions
-Most firearms made today are derivatives, variants or slight refinements of earlier designs, You can trace a direct lineage from Stoner's AR-18 to like half of all modern military rifles, The AR-18 in turn has DNA from Simonov rifles
-The only real advances in Firearms technology today are 1. Stronger materials, especially for use with high pressure ammunition coupled with reinforced actions 2. Ergonomics 3. QOL features largely for military customers but used as selling points for Civilians (Replaceable cam paths aka MCX, QD handguards, maritime capability, ease of maintenance etc etc) 3. Integration with """ Enablers""" (Lights, lasers, advanced optic systems, NV/Thermal)
If anything I would say there's at least an order of magnitude more innovation in the firearms accessory market than the actual firearms market.
Unless someone invents a radical new action or has a epiphany that makes every other firearm designer look like a drooling retard in one aspect or another, we're basically going to be using the guns we have today, with occasional refreshes and improvements, and have had for a long time for the foreseeable future until we can figure out a way to get batteries with power densities high enough to make laser guns or do the same with rail guns after fixing the rail durability problem, or just abolish infantry combat all together and make war a gamefied event where nerds controlling robots slaughter their physical avatars like it's a CounterStrike Match.
There have been dozens of future weapons programs for infantry small arms and most of them have failed because the prospective replacements are 1. Way too expensive/complicated for not enough improvements 2. Just not very good
