A few years ago, I picked up (3) sets of the Parker Enterprises T-Post Target Stand Brackets, and I'd like to recommend them for anyone who is wondering how to securely, yet temporarily, mount steel targets.
I've put them through some very hard use, and there's not a scratch on them.
Pro's:
- Well made. No sharp or rough edges
- Extremely durable. 3/8" AR-500 steel Need I say more?
- Stable. Once you've got your target(s) set up, these stands don't move.
Con's:
- Cost. At $35/ea plus shipping, they're not the cheapest solution.
- Finicky to set up. There's a learning curve. Watch the videos.
