The Precision Targets AR500 Duck Sr Target in 3/8" thick steel steps up the durability of this larger duck silhouette, giving shooters more caliber headroom than the 1/4" version. Cut from 3/8" AR500 steel, it handles repeated impacts from most centerfire rifle calibers without cratering, making it a solid choice for rifle training at a generous 10"x10" size. The larger footprint keeps it an easier, more forgiving aim point than the compact Ducky Jr, while the added thickness extends the range of calibers it can safely handle. It still delivers the sharp, resonant ring AR500 steel is known for, giving shooters instant audible and visual feedback on hits. A solid mid-tier option for shooters who want a big, rifle-rated duck target on the range. Precision Targets AR500 Duck Sr 10x10" 3/8" Thick Steel Target 10x10x3-8RDS
