ShootSteel.com Review
Over the past few months I reviewed targets from ShootSteel.com.
The targets shown are 3/8" thick, and 12"x20". They use a welded steel stand, with a 2x4 to mount the target on. The stands and mounting is top notch, and the targets are wonderful to shoot.
I highly suggest checking out ShootSteel.com
The firearms used on these targets included a Remington 870, Remington 700, Benelli M2 3 Gun Edition, HK 416D, CZ455, Sig Mosquito, IWI Tavor, a few ARs in 5.56 and 300 Blackout, 1911s, Glocks, and an M&P. (With a good chunk of those being in quiet mode)
