Not at all. I made the point that Retro AR Fever usually means an A1... including the new rage of non-FA receivers and such, you insist that the A2 is better. The A2 IS better, but if you want a retro A1, etc, for whatever reason, it's not going to be an A2. I also made the general point that most AR's likely never see ranges beyond 300M (that being the typical limit to the A1 sights without adjustment or Kentucky windage,) so an A1 is still a reasonable choice if you want to build retro, or even a modern AR. You have to know what you want, however. It's all about choices... welcome to the world of AR's.
There are two types of M16A1 clone builders aka AR15 A1's , Guys who used them and survived and Nostalgic want a B's .
Many AR shooters bang steel fairly regularly 200-800 Yd or meters . Other AR shooters use them hunting , mostly 7.62X51mm 6.5 CM ,so AR 10 platform or more correctly DPMS /LR .
I've built a fair # of AR's in various calibers over a few decades ,I also shoot them on a fairly regular basis ,weather permitting .
I build bastard units ,meaning I've got Mloc uppers with A2 furniture ALL of MY AR'S wear A2 stocks . I despise those Franken skeleton hockey golf putter contraptions being peddled as Butt Stocks . Just MY particular Quirk , I want a Rifle with a BUTTSTOCK ,not some airy adjustable walking cane .
As each marked improvement presses on in the AR saga ,I believe more and more builders will produce M4 clone models .
I'm willing to bet Money ,there are # 8:1 carbines verses Rifles and Lord only knows how many AR pistols produced .
One thing is absolutely certain ; Manufacturers will produce WHATEVER SELLS . Then regardless of sense buyers will cobble franken models of whatever they want . Such has been the Firearms history since it's beginning and will remain so , as long as Owners STAND UP and make politicians SHUT UP . IMO
