i mean the military get by just fine with good old iron sights and so on so why cant you?
I don't feel the need for 80mm objective lenses and 200 minute front base mounts on my rifle, but then, I don't compete in 1-mile matches, either. I don't own a 20 lb rifle, either.
I don't use the special aperture front sights found on many competition target rifles. This style was actually popular on military competition rifles. But back when I shot with the UT riflery team, I happily employed an Anshutz rifle with just such a front sight, which neatly held the small black bull perfectly in the aperture.
A lot of people feel that the intermediate (between the action and the muzzle) open rear sight found on the majority of rifles today is adequate. They feel no need --as I do-- to install upon their rifle a receiver-mounted aperture sight, which increases their sight radius, and (for me) accuracy. Of those who do, many people whould dislike my choice of aperture size (usually ghost-ring). I myself have little if any use for a full-buckhorn sight, while I know good shooters who will have nothing else.
My father, an active shooter of strong opinions, finds the shallow V rear and big glowing white dot on the Big Dot pistol sights to be a difficult proposition to accept. I find them appealing (having shot them one time), and have been present when a man with them outshot us both on the long-range portion of a pistol match. Is Dad wrong? He is if he claims that they don't work, period. He's on solid footing if he declares that they're not his cuppa tea, though.
I myself happen to find large scope rigs on the handy lever actions to be an abomination; they take a handy, sturdy rifle and turn it into an awkward, rather fragile thing. But not only are many fielded every year, but many are extremely successful with them. I know of more than one case where a hunter took a buck at over 200 paces with his Marlin, outfitted in just such a fashion.
The happy thing is that there are many different venues, and many different tastes. With all the different applications for the different rifles out there, why not try considering the possibilities, and if they don't meet your interests, moving on without judging? It's okay not to like it all. But just because it's not for you doesn't mean it's wrong, per se.
