You may have spotted a big black rubber shooting block in some of our recent articles. It is made by this company, Range Systems. We have found it a great replacement for sandbags and traditional cloth and metal rests because you can leave it outside. This SHOT video appointment was an education in the other stuff that the company makes, and it is far more advanced than a simple shooting block. Range Systems makes whole bulletproof rooms for law enforcement training, as well as gunsmith and home range traps, all based on the same thick rubber technology as our humble little range block. Now Range Systems is even making steel target systems, check out the video.
