Why ya gotta be like that?
Here is a man (Charles CZ75B [great platform, by the way]) that is exercising the old noodle to be a little bit more self-reliant and inventive, and you come in showing everyone a mass-produced and cheap alternative to DIY stands.
Then again, if it's lighter, it may be worth it.
If I had my own range, backyard, on my property, sure, I'd put up PVC type semi-permanent stands. But we use a shooting club, have to load everything in the car, set up, shoot, and pack up. We can do it all in about two hours, including driving time out and back. My gf can set up the targets move them, and grab two of them and toss 'em in the car herself.
So cost, time, weight, replaceability, mobility, storage space, believe me, these are impossible to beat. Buy four of them for about $58, and they last a year of 50 rounds per session, 15-30 shoots per year (more when ammo was cheaper).
I do applaud D-I-Y-S projects, but sometimes you need to grab and go.
